When cropping, the ImageEnView.SelectionAspectRaio will maintain the aspect ratio of the crop box. Is there a mechanism to display the center of the crop box while cropping an image and thus improve usability by identifying the center of the area to be cropped?
Ideally, horizontal and vertical lines could join the sides of the crop box at their centers. The point where the two lines crossed would identify the center of the crop box and at the same time the 4 quadrants of the crop box would be identified.
The is no built in provision to show the center of the selection. You may be able to achieve this by drawing the lines in the DrawBackbuffer event, but it will not be simple.
In the next release, if SelectionOptions includes iesoShowCenter, then a small cross will indicate the center of the selection (only while selection is in progress).
