Specifies the selection aspect ratio.

If SelectionAspectRatio is -1, the aspect ratio is active only when user press the ALT key, and it is automatically calculated.

If SelectionAspectRatio is 0, the size of the selection is fixed and determined by SelectionAbsWidth and SelectionAbsHeight properties.

If SelectionAspectRatio is >0, ImageEn maintains the specified aspect.

IEViewer1.SelectionAspectRatio=-1;

Example 2: we want a fixed selection of 100 x 100 pixels

CopyC#

IEViewer1.SelectionAbsWidth=100;

IEViewer1.SelectionAspectRatio=0;

Example 3: we want a fixed aspect ratio of 2 (height=2*width)

CopyC#

IEViewer1.SelectionAspectRatio=2;
