In some embodiments, the external port  34  is a multi-pin (e.g., 30-pin) connector that is the same as, or similar to and/or compatible with the 30-pin connector used on iPod® devices. 
     The contact/motion module may facilitate the detection and/or interpretation of contact with a touch sensitive input device, such as a touch screen, click wheel or touch pad. The contact/motion module includes various software components for performing various operations related to detection of contact, such as determining if contact has occurred (e.g., detecting a finger-down event), determining if there is movement of the contact and tracking the movement across the touch-sensitive surface (e.g., detecting one or more finger-dragging events), and determining if the contact has ceased (e.g., detecting a finger-up event or a break in contact). Determining movement of the point of contact, which is represented by a series of contact data, may include determining speed (magnitude), velocity (magnitude and direction), and/or an acceleration (a change in magnitude and/or direction) of the point of contact. These operations may be applied to single contacts (e.g., one finger contacts) or to multiple simultaneous contacts (e.g., “multitouch”/multiple finger contacts). 
     The graphics module includes various known software components for rendering and displaying graphics on the display  12  or other connected displays or projectors, including components for changing the intensity of graphics that are displayed. As used herein, the term “graphics” includes any object that can be displayed to a user. In some embodiments, the graphics module stores data representing graphics to be used. Each graphic may be assigned a corresponding code. The graphics module receives, from applications etc., one or more codes specifying graphics to be displayed along with, if necessary, coordinate data and other graphic property data, and then generates screen image data to output to the display controller  44 . 
     Examples of applications that may be stored in storage/memory  14  may include work productivity applications as well as other applications. Examples of such applications may include word processing applications, image editing applications, drawing applications, presentation applications, JAVA-enabled applications, encryption, digital rights management, voice recognition, and voice replication.

By way of example only, the depicted icons  82  may represent a presentation application  88 , such as Keynote® from Apple Inc., an application  90  for accessing the App Store® service from Apple Inc., an application  92  for accessing the iTunes® service from Apple Inc., as well as an e-reader/e-book application  94 . 
     In some embodiments, the selection of a particular icon  82  may lead to a hierarchical navigation process, such that selection of an icon  82  leads to a screen or opens another graphical window that includes one or more additional icons  82  or other GUI elements. By way of example only, the operating system GUI  52  displayed in  FIG. 4  may be from a version of the Mac OS® operating system, available from Apple Inc. 
     The multi-function device  70  also may include various external ports  34  that allow connection of the multi-function device  70  to external devices, such as computers, projectors, modems, telephones, external storage devices, and so forth. For example, one external port may be a port that allows the transmission and reception of data or commands between the multi-function device  70  and another electronic device, such as a computer. One or more of external ports  34  may be a proprietary port from Apple Inc. or may be an open standard I/O port. 
     With the foregoing discussion in mind, various techniques and algorithms for implementing aspects of the present disclosure on electronic devices  10  and associated hardware and/or memory devices are discussed below. For example, in certain implementations, an electronic device  10  may be employed to store and/or run a work productivity application or suite of applications. One example of such applications includes the Pages® word processing application, the Numbers® spreadsheet application, and the Keynote® presentation application, which are all provided within the iWork® application suite available from Apple Inc. of Cupertino, Calif. In certain embodiments, such applications, or aspects of such applications, may be encoded using a suitable object-oriented programming language, such as Objective-C, C++, C#, and so forth. 
     By way of example, a presentation application, such as Keynote® may be employed to generate and present slideshows, typically consisting of a sequential display of prepared slides. For example, turning to  FIG. 4 , an illustrative screen  120  of a presentation application is depicted in accordance with one embodiment of the disclosure. Such a presentation application may be stored as one or more executable routines in storage/memory  14  ( FIG. 1 ) and, when executed, may cause the display of screens, such as screen  120 , on a display  12 , such as a display configured for use as a touch screen. 
     Prior to discussing the use or features of a presentation application in accordance with the present disclosure, it should be appreciated that, as used herein, a “slide” should be understood to refer to a discrete unit on which one or more objects may be placed and arranged. Such slides should also be understood to be discrete units or elements of an ordered or sequential presentation, i.e., the slides are the pieces or units that are assembled and ordered to generate the presentation. Such a slide, may be understood to function as a container or receptacle for a set of objects (as discussed below) that together convey information about a particular concept or topic of the presentation. A slide may contain or include different types of objects (e.g., text, numbers, images, videos, charts, graphs, and/or audio, and so forth) that explain or describe a concept or topic to which the slide is directed and which may be handled or manipulated as a unit due to their being associated with or contained on the slide unit. 
     The order or sequence of the slides in a presentation or slideshow is typically relevant in that the information on the slides (which may include both alphanumeric (text and numbers) and graphical components) is meant to be presented or discussed in order or sequence and may build upon itself, such that the information on later slides is understandable in the context of information provided on preceding slides and would not be understood or meaningful in the absence of such context. That is, there is a narrative or explanatory flow associated with the ordering or sequence of the slides. As a result, if presented out of order, the information on the slides may be unintelligible or may otherwise fail to properly convey the information contained in the presentation. This should be understood to be in contrast to more simplistic or earlier usages of the term “slide” and “slideshow” where what was typically shown was not a series of multimedia slides containing sequentially ordered content, but projected photos or images which could typically be displayed in any order without loss of information or content. 
     As used herein, the term “object” refers to any individually editable component on a slide of a presentation. That is, something that can be added to a slide and/or be altered or edited on the slide, such as to change its location, orientation, size, opacity, color, or to change its content, may be described as an object. For example, a graphic, such as an image, photo, line drawing, clip-art, chart, table, which may be provided on a slide, may constitute an object. Likewise, a character or string of characters may constitute an object. Likewise, an embedded video or audio clip may also constitute an object that is a component of a slide. Therefore, in certain embodiments, characters and/or character strings (alphabetic, numeric, and/or symbolic), image files (.jpg, .bmp, .gif, .tif, .png, .cgm, .svg, .pdf, .wmf, and so forth), video files (.avi, .mov, .mp4, .mpg, .qt, .rm, .swf, .wmv, and so forth) and other multimedia files or other files in general may constitute “objects” as used herein. In certain graphics processing contexts, the term “object” may be used interchangeably with terms such as “bitmap” or “texture”. 
     Further, because a slide may contain multiple objects, the objects on a slide may have an associated z-ordering (i.e., depth) characterizing how the objects are displayed on the slide. That is, to the extent that objects on the slide may overlap or interact with one another, they may be ordered, layered or stacked in the z-dimension with respect to a viewer (i.e., to convey depth) such that each object is ordered as being above or beneath the other objects as they appear on the slide. As a result, in the event of an overlap of objects, a higher object can be depicted as overlying or obscuring a lower object. In this way, a slide may not only have a width and length associated with it, but also a depth (i.e., a z-axis). 
     Thus, as used herein, the term “slide” should be understood to represent a discrete unit of a slideshow presentation on which objects may be placed or manipulated. Likewise, an “object” as used herein should be understood to be any individually editable component that may be placed on such a slide. Further, as used herein, the term “transition” describes the act of moving from one slide to the next slide in a presentation. Such transitions may be accompanied by animations or effects applied to one or both of the incoming and outgoing slide. Likewise, the term “build” as used herein should be understood as describing effects or animations applied to one or more objects provided on a slide or, in some instances to an object or objects that are present on both an outgoing and incoming slide. For example, an animation build applied to an object on a slide may cause the object to be moved and rotated on the slide when the slide is displayed. Likewise, an opacity build applied to an object on a slide may cause the object to fade in and/or fade out on the slide when the slide is displayed. 
     With the foregoing in mind, and turning to  FIG. 4 , it will be appreciated that, in certain embodiments a presentation application may provide multiple modes of operation, such as an edit mode, an animation mode, a presentation or play mode, and so forth. When in the edit mode, the presentation application may provide an interface for a user to add, edit, remove, or otherwise modify the slides of a slide show, such as by adding text, numeric, graphic, or video objects to a slide. Likewise, when in the animation mode, the presentation application may provide an interface for a user to apply and/or modify animation or effects applied to slide transitions between slides or to builds (e.g., animations, effects, and so forth) applied to objects on a slide. To display a created slide or a sequence of slides in a format suitable for audience viewing, a presentation mode of the presentation application may be employed which displays the slides, slide transitions, and object builds in a specified sequence. In some embodiments, the presentation application may provide a full-screen presentation of the slides in the presentation mode, including any animations, transitions, builds or other properties defined for each slide and/or object within the slides. 
     The screen  120  of  FIG. 4  represents a screen that may be displayed when one embodiment of a presentation application is in an edit mode, such as for slide creation or modification. In the depicted example, the screen  120  includes three panes: a slide organizer or navigator pane  124 , a slide canvas  128 , and a toolbar  132  for creating and editing various aspects of a slide  140  of a presentation. By using these panes, a user may select a slide  140  of a presentation, add objects  142  to and/or edit objects  142  on the slide  140  (such as the depicted graphic objects and character objects), and animate or add effects related to the slide or the objects  142  on the slide  140 . 
     The navigator pane  124  may display a representation  150  of each slide  140  of a presentation that is being generated or edited. The slide representations  150  may take on a variety of forms, such as an outline of the text in the slide  140  or a thumbnail image of the slide  140 . Navigator pane  124  may allow the user to organize the slides  140  prepared using the application. For example, the user may determine or manipulate the order in which the slides  140  are presented by dragging a slide representation  150  from one relative position to another. In certain embodiments, the slides representations  150  in the navigator pane  124  may be indented or otherwise visually set apart for further organizational clarity. In addition, in certain embodiments, the navigator pane  124  may include an option  152  which, when selected, adds a new slide to the presentation. After being added, the slide representation  150  for such a new slide may be selected in the navigator pane  124  to display the slide  140  on the canvas  128  where objects  142  may be added to the new slide  140  and/or the properties of the new slide  140  may be manipulated. 
     In certain implementations, selection of a slide representation  150  in the navigator pane  124  results in the presentation application displaying the corresponding slide information on the slide canvas  128 . For example, for a selected slide representation (here depicted as slide  3 , identified by highlight region  154 ) the corresponding slide  140  may be displayed on the slide canvas  128 . The displayed slide  140  may include one or more suitable objects  142  such as, for example, text, images, graphics, video, or any other suitable object. In some embodiments, a user may add or edit features or properties of a slide  140  when displayed on the slide canvas  128 , such as slide transitions, slide background, and so forth. In addition, in some embodiments a user may add objects  142  to or remove objects  142  from the slide  140  or may manipulate an object  142  on the slide  140 , such as to change the location or appearance of the object  142  or to add or edit animations or builds to the object  142 . The user may select a different slide  140  to be displayed for editing on slide canvas  124  by selecting a different slide representation  150  from the navigator pane  124 , such as by touching the displayed slide representation  150  in a touch screen embodiment of the device  10 . 
     In the depicted implementation a user may customize objects  142  associated with the slide  140  or the properties of the slide  140  using various tools provided by the presentation application. For example, in certain embodiments, when in the edit mode, selection of a slide  140 , object  142 , and/or toolbar option  158  may cause the display of an interface presenting one or more selectable options for the selected slide  140  or object  142 , which a user may then select, deselect, or otherwise manipulate to modify the slide  140  or object  142  as desired. For example, selection of certain toolbar options  158 , such as an inspector or information icon  160 , may cause properties of the selected object  142  or slide  140  to be displayed for review and/or modification. Likewise, selection of an animation mode icon  162  from among the toolbar options  158  may cause the presentation application to enter an animation mode from which builds or animations applied to objects and/or transitions assigned to slides may be reviewed, edited, and/or manipulated. Similarly, selection of a play mode icon  164  from among the toolbar options  158  may cause the presentation application to enter a presentation mode in which the slides  140  of the slide presentation are sequentially displayed on the display  12  or an attached display device. 
     Additionally, the electronic device  10  may include image editing capabilities, such as the ability to resize, rotate, move, crop, or otherwise edit an image object of a slide. In some embodiments, for example, the electronic device  10  may include an image editing mode having an image mask to provide image cropping and other editing functions.  FIGS. 5-16  below depict the image mask and image editing functions of an exemplary embodiment of the electronic device  10 . As described in detail below, in some editing functions, the image mask may be manipulated separately from the image object. In other editing functions, the image mask and image object may manipulated together while the size of the image mask relative to the image object is maintained. The image masking feature may be operable on different embodiments of the electronic device  10 , e.g., the laptop  40  or the multi-function electronic device  70 . For example, in some embodiments the image editing functions described below may be activated by a touchscreen, e.g., display  12 , to provide faster and easier selection and editing of an image, or multiple images. For example, a user may interact with touch sensitive elements  76  of the multi-function device  70  to perform some or all of the image editing capabilities described below. It should be appreciated that such interactions with the touchscreen, e.g., display  12 , may be referred to as “gestures.” Thus, as used below, the terms “select,” “hold,” and “move” with reference to the various image editing functions may include any suitable action involving an embodiment of the electronic device  10 , such that “select” may include touching a touchscreen with an appendage or stylus, or clicking a cursor location on a display with a mouse button or pressing a key or keys on a keyboard. Similarly, “hold” may include maintaining contact between a touchscreen and an appendage or stylus, or maintaining depression of a mouse button or a key on a keyboard. In like manner, “move” may include moving an appendage or stylus over a touchscreen, or moving a cursor on a display by moving a mouse or depressing keys on a keyboard. 
     Turning now to  FIG. 5 ,  FIG. 5  depicts a screen  170  of the electronic device  10  that may be displayed after a user has selected one of a slide  172  for editing. As noted above, the screen  170  also depicts the slide organizer or navigator pane  124 , the slide canvas  128 , and the toolbar  132 . The selected slide  172  may include an image object  174  that is displayed on the slide canvas  128 . Although  FIGS. 5-16  are described with reference to a single image object  174 , it should be appreciated that the techniques described below and illustrated in  FIGS. 5-16  may be applied to multiple image objects of a selected slide displayed on the slide canvas  128 . 
     To enter an image editing mode, a user may perform an appropriate interaction with the electronic device  10 . For example, the user may select an icon displayed on the screen  170  of the electronic device  10 , such as by selecting (e.g., touching) the inspector or information icon  160 . Alternatively, a user may “double tap” or “double click” any portion of the image object  172  to enter the image editing mode. 
     Upon initiation of an image editing mode, an image mask is created and displayed on the slide canvas  128 .  FIG. 6  depicts a screen  176  of the electronic device  10  showing an image mask  178  overlying the image object  174 . In one embodiment, the initial size (e.g., height and width dimensions) of the aperture of the image mask  178  is the same size (e.g., height and width dimensions) as the image object  174 , such that the frame of the image mask  178  aligns with the border  180  of the image object  174 . Additionally, after creation of the image mask  178 , a slider  182  may be displayed on the slide canvas  128 . The slider  182  may be used to manipulate the size of the image object  174 , and may be manipulated by moving a slide button  184  along a slide axis  186 . As discussed further below, in one embodiment the slider  182  may correspond to the ratio of a dimension of the image object  174  to a dimension of the aperture of the image mask  178 . In one embodiment, the slider  182  (and the position of the slider button  184  on the slide axis  186 ) may correspond to the greater of the ratio of the image object height to the mask aperture height or the ratio of the image object width to the mask aperture width. For example, such a ratio may have a value of 1 when the slide button  184  is located in the position shown in  FIG. 6 . A “DONE” icon  188  may be displayed proximate to the slider  182  to receive an indication that the image masking process is complete. 
       FIG. 7  depicts a screen  181  of the electronic device  10  showing the image mask  178  resized to mask a portion of the image object  174 . The image mask  178  includes a mask aperture  190  and a mask frame  192 . In some embodiments, the mask frame  192  may be colored, shaded, translucent, opaque, or otherwise distinguished from the mask aperture  190 . The mask frame  192  corresponds to those portions of the image object  174  that will be cropped when the image masking process is completed. The aperture  190  corresponds to the portion of the image object  174  that will remain after cropping. 
     The image object  174  may be resized by moving the slider button  184 . As depicted in  FIG. 7 , the image object  154  may have a height H 1  and a width W 1  and the aperture  190  may have a height HA and a width WA. Thus, in the intermediate position shown in  FIG. 7 , the slider  182  corresponds to a ratio of the dimension of the image object to the dimension of the mask aperture that is greater than one, e.g., the greater of the ratio of H 1 /HA or W 1 /WA. 
     As also shown in  FIG. 7 , the border  193  between the mask aperture  190  and the mask frame  192  may include knobs  194  located at multiple points around the border. In one embodiment, the knobs  194  may be located at the midpoint of each edge of the border and at the intersection of each edge of the border. The knobs  194  may be selected (e.g., touched) and dragged on the screen  170  to resize the image mask  178 . For example, as shown in  FIG. 7 , the knob  196  may be selected (e.g., touched) and dragged along line  198  to resize the image mask  178 . If any of the knobs  196  are selected and dragged to resize the image mask  178 , the slider  182  may change interactively to reflect the resize of the image mask  178 . 
     As mentioned above, the slider  182  controls the size of the image object  174 . Thus, to change the size of the image object  174 , a user may select (e.g., touch) the slider button  184  and move the slider button  184  along the axis  186 . For example, as shown in  FIG. 7 , to reduce the size of the image object  174 , a user may move the slider button  184  in the direction depicted by arrow  199 . As the slider button  184  moves along the axis  186 , the image object  174  may be continuously updated to reflect the new position of the slider  182 . 
       FIG. 8  depicts a screen  200  of the electronic device  10  showing the image object  174  resized in response to movement of the slider  182 . As shown in  FIG. 8 , the image object  174  has a reduced height H 2  and reduced width W 2  that correspond to the new position of the slider  182 . The mask aperture  190  is the same size position and size. Thus, movement of the slider  182  resizes the image object  174  separately from resizing of the mask aperture  190 . Accordingly, the mask frame  192  is also reduced in size to indicate those reduced portions of the image object  174  that will be cropped. As mentioned above, as the slider  182  may indicate the ratio of a dimension of the image object  174  to a dimension of the mask aperture  190 , the slider  82  may now correspond to the greater of H 2 /HA or W 2 /WA. To increase the size of the image object  174 , the slider button  184  may be moved along the slider axis  186  in the direction indicated by arrow  202 . In this manner, the slider  182  may be used to manipulate the image object  174 , and the knobs  194  may be used to manipulate the mask aperture  190 . 
     Additionally, the image object  174  (and image mask  178 ) may be resized such that the proportional size relationship between the image mask  178  and the image object  174  is maintained.  FIGS. 9 and 10  depict screens of the electronic device  10  illustrating resizing of the image object  174  from a first height (H 1 ) and width (W 1 ) to a second height (H 2 ) and width (W 2 ). As shown in a screen  203  of the electronic device  10  depicted in  FIG. 9 , in one embodiment the image object  174  may be resized (e.g., reduced in size) by simultaneously selecting (e.g., touching) a first region  204  of the slide canvas  128  and a second region  205  of the slide canvas  128  and “pinching” the selection regions  204  and  205 , such as along line  206 . In other embodiments, the image object  174  may be resized by selecting (e.g., touching) a corner of the image object  174  and dragging the corner on the slide canvas  128 . During the resize of the image object  174 , the image mask  178  may be resized to maintain the current ratio between the image mask  178  and the image object  174 . For example, visible or invisible guides (such as snap points), may assist in maintaining the current ratio. 
     As shown in screen  207  of the electronic device  10  depicted in  FIG. 10 , after resizing of the image object  174 , both the image object  174  and the image mask  178  have resized proportional to each other. Thus, the image object  174  and the image mask  178  (including the mask aperture  190  and the mask frame  192 ) have reduced in size. As seen in  FIG. 10 , the position of the slider  182  remains in the same position as in  FIG. 9 , as the size of the image object  174  relative to the mask aperture  190  is unchanged. In one embodiment, the image object  174  may be resized (e.g., increased in size) by simultaneously selecting (e.g., touching) a first region  208  of the slide canvas  128  and a second region  209  of the slide canvas  128  and “pinching” the selection regions  208  and  209 , such as along line  210 . In other embodiments, as mentioned above, the image object  174  may be resized by selecting (e.g., touching) a corner of the image object  174  and dragging the corner on the slide canvas  128 . 
     Additionally, the image editing mode may enable movement of the image object  174  on the slide canvas  128 , and/or movement of the image mask  178  on the slide canvas  128 . Depending on the selection interaction, either the image object  174  or the image mask  178  may be moved on the slide canvas  128 . As described further below,  FIGS. 11 and 12  depict movement of the image object  174  around the slide canvas  128 . 
     In one embodiment, the image object  174  may be moved on the slide canvas  128  by selecting (e.g., touching) the image object  174  and moving the image object  174  on the slide canvas  128 .  FIG. 11  depicts a screen  211  of electronic device  10  showing the image object  174  in a first position on the slide canvas  128 , and  FIG. 12  depicts a screen  213  of the electronic device  10  showing the image object  174  in a second position on the slide canvas  128 . As shown in  FIG. 11 , a first region  212  in the image object  174  may be selected and moved, such as in the direction indicated by line  214 , to move the image object  174  in the direction of line  214 . Any region  212  of the image object  174 , either in the mask aperture  190  or in the mask frame  192 , may be selected to enable movement of the image object  174 . In such an embodiment, movement of the image object  174  does not move the image aperture  190  such that the image mask  178  maintains its position on the slide canvas  128 . The mask frame  192  of the image mask  178  expands to overlay the moved portions of the image object  156  and indicated which portions of the move image object  156  will be cropped. In this manner, the object  156  may be moved separately from the image mask  178 . 
       FIG. 12  depicts a screen  215  of the electronic device  10  showing the image object  174  moved to the second position on the slide canvas  128 . As noted above, the image aperture  190  of the image mask  178  is in the same position on the slide canvas  128 . Thus, the image move function enables movement of the image object  174  on the slide canvas  128  separately from the image mask  178 . 
     Additionally, the image editing mode may enable rotation of the image object  174  and the image mask  178 . In one embodiment, the image object  174  may be rotated on the slide canvas  128  by selecting a first region in the image object  174  (or the image mask  178 ) and rotating a second selected region around the first region.  FIGS. 13 and 14  depict rotation of the image object  174  on the slide canvas  128  between a first position and a second position. 
       FIG. 13  depicts a screen  220  showing the image object  156  in a first position on the slide canvas  128 . To rotate the image object  174 , a first region  222  on the image object  174  may be selected (e.g., touched) onto the slide canvas  128  and onto the image object  174 , and a second region  224  on the image object  174  may be simultaneously selected (e.g., touched). The first region  222  and second region  224  may be any region in the image object  174 , including the image mask  178 . Once both regions are selected, to rotate the image object  174  counterclockwise, the second region  224  may be moved around the first region  222  in a counterclockwise direction, as indicated by arrow  226 . Similarly, once both regions are selected, to rotate the image object  174  clockwise, the second region  224  may be moved in a clockwise direction around the first region  222  in a counter clockwise direction, as indicated by line  228 . After selection of both regions  222  and  224 , the first region  222  may be released the image object  174  may be rotated by moving the second region  224 . The image object  174  rotates around a z-axis extending through the center  230  of the image object  174 . 
       FIG. 14  depicts a screen  232  showing the image object  174  in a second position after rotation in the counterclockwise direction indicated by line  228 . As shown in  FIG. 14 , the image object  174  rotates around the center  230  of the image object  174 . The mask aperture  190  maintains its position on the slide canvas  128  during and after the rotation. The mask frame  192  rotates accordingly to overlay those portions of the image object  174  outside of the image aperture  190 . The image object  174  may be rotated in any direction and in any region of the slide canvas  128  in the manner described above. 
     After a user has edited the image object  174 , such as be moving, sizing and rotating the image object  174  and the image mask  178  as described above, the user may complete the editing process. The image edit mode may include multiple interactions to exit the image edit mode. For example, the user may select (e.g., touch) the “DONE” icon  188 , depicted above in  FIGS. 6-14 . In another example, the user may “double tap” (e.g., touch twice in quick succession) any region on the slide canvas  128  outside of the image object  174 .  FIG. 15  depicts a screen  236  showing the edited image object  238  after a user has completed the image edit process. The image object  174  has been cropped by the image mask  178  depicted above in  FIG. 7 . As shown in  FIG. 15 , those portions of the image object  174  underlying the mask frame  192  have been removed from the image object  174  and are no longer displayed on the slide canvas  128 . Accordingly, those portions of the original image object  174  visible through aperture  190  are the edited image object  238 . 
     In some embodiments, the image editing feature of the multi-function electronic device  70  may be capable of importing and/or creating an image mask of any size and shape.  FIG. 16  depicts a screen  240  of the electronic device  10  during an image editing process showing an image object  242  having an image mask  244 . The image mask  244  shown in  FIG. 16  is an irregular shaped polygon having an irregular shaped frame  246  and aperture  248 . The image mask  246  includes knobs  250  arranged at the border  252  of the frame  246  and the aperture  248 . The slider  182  corresponding to the size of the image mask  246  relative to the image object  242  may be displayed on the slide canvas  128 . As described above, the slider  182  may change the relative size of the image mask  244  by moving the slide button  184  along the slide axis  186 , and the “DONE” icon  188  may be selected (e.g., touched) to indicate completion of the editing process. In some embodiments, the slider  182  may be used to change the shape of the image mask  178 . Alternatively, to resize the image mask  244 , any of the knobs  250  may be selected and moved over the slide canvas. As also described above, the image mask  244  may be moved by selecting and holding the mask frame  246  and moving the image mask on the slide canvas  128 . 
       FIG. 17  depicts a process  260  summarizing the image editing functions described above. As noted above, the process  260  may be implemented as routines executable by a processor and stored as a computer program product on tangible computer-readable media, such as storage memory components  14 . Initially, the device  10  may enter an image editing mode (block  262 ) for an image object, based on a selection from a user. Upon initiation of the image editing mode, an image mask may be created and overlaid on the image object (block  264 ). As described above, the image mask may initially include a mask aperture having the same dimensions as the image object. The electronic device  10  may resize the image mask based on actions received from a user (block  266 ), such as movement of the knobs of the mask frame and/or movement of the slider. 
     As described above, various editing functions may occur on the electronic device  10 . The image object may be moved (block  268 ) in response to actions received from a user, such as by the user selecting and holding image object through the mask aperture and moving the image object on the slide canvas. Further, the image object may be rotated (block  270 ) based on a actions received from a user, such as by the user selecting and holding a first region on the image object and rotating a second selected region around the first region. After receiving completion of the image editing process, such as by a user selecting the “DONE” icon on the slide canvas, the image object may be cropped based on the image mask (block  272 ). 
     The specific embodiments described above have been shown by way of example, and it should be understood that these embodiments may be susceptible to various modifications and alternative forms. It should be further understood that the claims are not intended to be limited to the particular forms disclosed, but rather to cover all modifications, equivalents, and alternatives falling within the spirit and scope of this disclosure.
