Re: DDRAW levels of resolution and picture quality

What are the specific steps you are taking where you see this issue?

For example:
* create DirectDraw object
* create Surface
* create Overlay
* call UpdateOverlay
Etc.

Win CE 5.0:

Does ddraw.dll support any other resolutions than 1/1, 1/2 and 1/4
without
streching the image?

When you set the size of the video window to height 5/6 of full screen
and
width 5/6 of full screen. ddraw.dll shrinks the video input to 1/2 and
the
streches the image to 5/6 by 5/6 of full screen. Thereby you get the
same
picture quality as you would if the video window size would be 1/2 x
1/2
of
full screen. The video image is just streched. I want ddraw.dll to only
shrink the video input to 2/3 of full screen so the picture quality
doesn't
become so poor. In pixels full screen is 800 x 600 px. The size of the
video
window which we want to use it 560 x 370 px.

Is it possible to improve the quality of the picture somehow?
