Stamp Annotation L_AnnMove() painting issue - Stamp Annotation Display Question L_AnnMove() Painting

I have a situation where I add a stamp annotation to an image. In this case a bitmap of a rectangle with a thin line outlining the bitmap.
When I add the annotation to the image it looks correct. However when I move the annotation with L_AnnMove() the thin line on the edge of the bitmap is not displayed.
As I move the annotation around the page, the lines go from visible to invisible.

Any ideas?

Hello Andrew,

Apologies for the delay in getting back to you. I believe the issue is simply a matter of sampling/interpolation. If the annotation isn't placed exactly on an integer position or the view is scaled, a single pixel line might not get rendered. How are you displaying the annotations? Are you ensuring you are placing the annotations at integer coordinates only?

Thanks,

Ah, the stamp can be moved and I never considered forcing the position to integer values. Both the image and the stamp annotation can also be resized. Will give position a tweak and see what happens. Thanks!
