With Tif images we use the Rotate method which works fine but the background is always black and not white as we require. We tried both methods but with no success.
When I load a TIFF image into ImageEnMView here I do not get a black background. I do not get a black background after rotation. I can not duplicate what you are seeing. Your attached photo is not visible in the forum.
If a scanned image is loaded where part of the image itself is black then black does appear in the thumbnail. The black part of the image is not the background... it is part of the scanned image as shown: 79.83 KB Here the area surrounding the paper is black and the background is white. The only way you can fix this is by filling the black with white.
Thanks for your reply. We determined that the second param needed to be true so AntialiasMode was used. Once changed we where able to change the background color to white.
You testing program look very interesting is this available.
