## Background
BACKGROUND
Technologies such as Cascading Style Sheets have given web designers increased control over the layouts of web pages. With these new technologies, elements in a web page do not have to be aligned from either the left or the right margin of the page. Instead, elements can now be positioned in any location, such as a number of pixels from the top, bottom, left or right. This increase in flexibility has led to many new and visually appealing web page design techniques. However, the positioning flexibility has also caused an increase in design complexity.

DETAILED DESCRIPTION
The detailed description provided below in connection with the appended drawings is intended as a description of the present examples and is not intended to represent the only forms in which the present example may be constructed or utilized. The description sets forth the functions of the example and the sequence of steps for constructing and operating the example. However, the same or equivalent functions and sequences may be accomplished by different examples.
Although the present examples are described and illustrated herein as being implemented in a system for measuring elements in a web page, the system described is provided as an example and not a limitation. As those skilled in the art will appreciate, the present examples are suitable for application in a variety of different types of systems that are capable of measuring the dimension of an element and the distance between elements in a graphically rendered document.
FIG. 1 shows an example system 100 for analyzing a web page. Analytical tool 105 is an executable component for measuring distances between points in web page 125. Analytical tool 105 may be an independent component or a part of another executable component. For example, in one example implementation, analytical tool 105 is a utility of a web browser. As shown in FIG. 1, analytical tool 105 may include indication processor 113, element detector 116, distance calculator 119, and information display manager 121.
Indication processor 113 is configured to identify locations that are indicated on a web page. For example, a user may use a pointing device to indicate two locations on the web page for measurement. The locations may also be provided by other executable components associated with the analytical tool 105. Typically, indication processor 113 identifies the locations by pixel coordinates in the web page.
Element detector 116 is configured to determine the elements that are in proximity to the locations identified by indication processor 113. In one implementation, element detector 116 is configured to identify an element within a predetermined distance from an indicated location. For example, element detector 116 may identify the element that is within 3 pixels of a location in the web page indicated by a user. Element detector 116 is also configured to determine a point on the identified element associated with the indicator location. The determined point typically is the most appropriate location in the element for measurement purposes. For example, the determined point may be on an edge of the identified element closest to the indicated location.
Distance calculator 119 is configured to calculate the distance between two points determined by element detectors 116 in one or more identified elements. The determined points may be on different elements but may also be on the same element. For example, two determined points may be on different edges of the same element. Distance calculator 119 is configured to obtain the coordinates of two determined points and calculates the distance between the points from the coordinates. The distance calculator 119 may determine the distance in any unit, such as pixel width, inches, centimeters, or the like.
Information display manager 121 is configured to display information provided by analytical tool 105. The information typically includes the distance between locations indicated on the web page. The information may also include the coordinates of the points automatically determined by element detector 116. The information may also include graphical aids. For example, a ruler may be displayed on the web page between the automatically determined points.
Analytical tool 105 may provide selectable options that further enhance usability. For example, analytical tool 105 may enable the selection the measurement be performed on the vertical or horizontal axes so that vertical or horizontal measurements can be automatically made. Analytical tool 105 may also enable a user to select the color of the ruler and whether to display tick marks and end points of the ruler. Analytical tool 105 may further enable the user to activate a zoom display area that magnifies a particular section of the web page so that the user can more accurately indicate the locations on the web page for measurement within the zoom display area.
Analytical tool 105 described above enables a user to accurately select points on a web page for measurement. Particularly, analytical tool 105 automatically determines the points on one or more elements from locations indicated by the user on the web page. Thus, the end points of a measurement are automatically snapped to elements proximate to the indicated locations. This functionality allows the user to select two meaningful points for measurement by merely indicating locations that are proximate to those points. Since the points are automatically snapped to elements on the web page, the performed measurement is highly accurate, without requiring the user to actually indicate the exact positions of the points on the web page.
FIG. 2 shows a screenshot 200 of an example user-interface for a snap to element analytical tool. The example analytical tool in FIG. 2 is shown as a ruler utility of a web browser 201. As discussed above, the analytical tool may also be incorporated into other types of applications or may execute as an independent component.
As shown in FIG. 2, web browser 201 includes tool bar 203 containing selectors for activating functionalities of web browser 201. In this example, tool bar 203 includes selector 205 for activating the ruler utility, which can be used to measure distances in web page 209, such as the distance between features in an element or the distance between different elements. When selector 205 is activated, the ruler utility provides option interface 207 for selecting different options offered by the rule utility. In the example, a “Snap to Element” option is selected, which enables the points between which a distance is calculated to be automatically snapped to an element in proximity to indicated locations on web page 209. Option interface 207 also includes a “Snap to XY Axis” option that automatically allows vertical and horizontal distances to be measured, a “Hide Tick Marks” option that hides the marks on the ruler, and a “Hide Endpoints” option that hides the determined points on the web page.
Screenshot 200 shows the ruler utility being used to measure element 214, which is a search box display feature of web page 209. As shown in FIG. 2, element 214 includes edges 216 and 217. A user may indicate the sides of element 214 for measuring. For example, the user may use a mouse to select locations proximate to edges 216 and 217. The ruler utility automatically determines points 212 and 213, which are located on the ends of edges 216 and 217. The ruler utility calculates the distance value between determined points 212-213 and displays value 223 on the web page, which is in pixel units in this example. As shown in screenshot 200, the ruler utility also displays a graphical ruler 221 on the web page between points 212-213. The rule utility further displays the coordinates of points 212-213 for user reference.
FIG. 3 shows another screenshot 300 of example web browser 201 with a snap to element analytical tool. As shown in FIG. 3, the ruler utility provides a zoom display area 302 to aid the user to indicate locations in web page 209 for measurement. Zoom display area 302 may be activated by a user or automatically by the ruler utility. In this example, the indicated locations are determined to be points on elements 304-305. The distance between elements 304-305 is calculated and the distance information 308 is displayed on the web page 209.
FIG. 4 shows an example process 400 for measuring distance between points on a web page that are automatically determined based on locations indicated by a user. Process 400 may be implemented by an analytical tool with snap to element functionalities. The analytical tool may be incorporated into a web browser or other applications, or may function as an independent component. At block 402, a selection to perform a measurement on a web page is received. At block 404, a location on the web page is identified. The location is typically provided by a user as an indication on the web page using a pointing device. At block 406, a first point in an element associated with the location is determined. For example, an element within a predetermined distance (e.g. 1-10 pixels) from the indicated location may be automatically identified.
At block 408, another indicated location may be identified. At block 410, a second point in an element associated with the other indicated location is determined. The second point may be on the same or different element from the element on which the first point is located. At block 412, the distance between the first point and second point is calculated. At block 414, the calculated distance is displayed on the web page. A graphical representation of a ruler may also be displayed. The ruler may connect the first and second points on the web page.
