Emerson,

I've been thinking alittle bit more on this issue...
I think I know what happens.

As you know, for GdiPlus-X, we use the Image Canvas a lot in our samples.
This control basically saves the desired images to streams, retrieves the binaries and stores these contents at the PictureVal property of the image control.

Me and Bo noticed that the image rendered by Picture and PictureVal are different too.
The image in PictureVal appears "blurred", even when we don't want, it seems to use always an ANTI-ALIAS interpolation mode.

In your case, as your original image is just one pixel wide, and you expect the image object to repeat the drawing multiple times, till it fills the control, VFP seems to use always the last pixel rendered and copies for the next column. This is why it seems to be changing the image, creating a new ugly and undesired gradient.

The only worrkaround that I can think at this moment is that you create your image much wider than only one pixel wide. Using the sample image that you provided, 30 pixels wide created a satisfactory result.


We need to report this urgently to MS, let's try to deal with this in PVT, and after that we call the community to test and maybe help us validating this problem at MS support.
