Details of the operators are discussed in the next chapter. Selecting an item from the menu will create a new instance of the chosen operator which then is placed on the worksheet. Menu items of optional operators are marked with a star. The Options menu lets the user control the grid used by the worksheet. The grid can be used to keep the operators neatly aligned.
Preferences Displays a dialog where important preferences can be set.
Snap When snapping is enabled, the operators snap to the grid when moved. This sub-menu allows to set the size of the grid for operator snapping. The specified size is relative to the size of an operator. The Help menu offers online access to the different chapters of the documentation. Future versions of ImgLab will make use of an integrated HTML help browser.
