The image displayed as its complement is related to:
cdCanvasWriteMode(handles.cd_canvas, IUP_CD.CD_NOT_XOR)
Probably there is a case where it missed the reset to normal, which
actually I just did not find in your code.
This:
IupSetAttributes(IupFill(),"SIZE=5, EXPAND=NO"),
Can be reduced to:
IupSetAttributes(IupFill(),"SIZE=5"),
Because setting the size of a IupFill already has that effect. It is a
special control with a different behavior for size.
I wouldn't recommend setting the size of the canvas inside it own action
callback. This could cause an infinite loop. You could load the image, only
once, some where else, then set the size and only redraw the image on the
action callback. im_view actually does exactly that, except for the size.
Also changing the size of the dialog every time you load a new image can
have a very unpleasant effect on screen. Sometimes it is simpler to load
the image and redraw in the space you have available. But this is up to you.
