I am having this strange problem, I hope you can help me !
While working on a project, I discovered a problem using BitBlt, when I'm drawing a scaled part of a bitmap onto a presentation spac.
I have a bitmap of (exsample) 1300*1200 poxels, from this I cut the lower left 200 * 200 pixels and draw them in a window.
If I draw the bitmap in 200*200 (or less) I have no problem.
If I scale the bitmap to (exsample) 300*300, it looks like I get the TOP left 200*200 of my source bitmap ?
This is the result no matter what I scale to as long as it is larger than my source rectangle !
When I move my source rectangle upwards, it looks as if it moves downwards, as if the Y axis has been swapped !
I have found the same problem in PMJPEG 2.03.
I'm fairly shure I havn't seen this problem before, but I have lately ibstalled SciTech Snap, and now I'm wondering if this is a known problem ?
I'm using Snap SE build 430 (downloaded from IBM yesterday).
Hope you can help.
