In the CropTool demo, procedure TForm1.LockControlClick refers to CropToolInteraction.LockWidth and CropToolInteraction.LockHeight. These are properties that no longer exist.
The demo compiles ok if I comment out the code in this procedure.
Will you be updating the demo to show Rotated Crop? That looks a really good feature.
LockWidth and LockHeight are current properties. Are you sure you are linking ImageEn 6.3.2?
You can rotate the crop in the current demo, by dragging outside the crop rect. But there is an issue in 6.3.2 that the cursors may not change indicating that rotation is available.
In v6.3.2B, there is updated source code and demos that are newer than the compiled packages. Officially LockWidth and LockHeight are not supported till the next release (or you can link to the updated source code in your installation).
