Annotation leaves pixels behind when dragging
« on: 2011 January 01 14:07:52 »

Hi,

didn't read about the annotation module yet. Nice addition! When I dragged the annotation to place it, it left pixels behind. This only happens when the image is reduced in size so it's smaller than the view port. See the attached.
Best,

Hi, yes, I'm aware of it. It seems that calculation of invalidate rectangle is not completely correct for zoomed-out images. I'm planning version 1.1 with opacity slider and some small improvements, so I'll address this problem as well.

regards, Zbynek
