Is there a Modified (or something similar) property of either TImageEnDBView or TImageEnView? What I would like to do in the FormClose insert something like:

if edtPhoto.Modifed then begin
Ask User if they want to save changes
if Yes then
Post Changes
else
Cancel Changes
end

TIA
Luke

If LegacyBitmap is true then you can access the ImageEnView.Bitmap.Modified property.

The ImageEnView.Bitmap.Modified property is not automatically set when the bitmap changes so you have to do that manually in code:
ImageEnView.Proc.ConvertToGray;
ImageEnView.Bitmap.Modified := True;

Also... 
ImageEnView.Bitmap.Modified := ImageEnView.Proc.CanUndo;

If LegacyBitmap is false then there is no ImageEnView.Bitmap so there is no ImageEnView.Bitmap.Modified property. In this case just create your own global boolean variable AModified: boolean, and use that to track if the image has been modified.
