HARD STUFF with IPicture

[IonelBurtan]

I have a SDK aplication very much like ADCSee.

I am using IPicture to load images and I an having these problems:

1.Independent of the file format the colors of the pictures are blured and the picture is wrecked. (However this does not happen if the picture ids displayed in ACDSee or another picture viewer which perhaps uses other techniques)
This happens only when running in 65535 colors.

2. how do you scroll a picture realized with IPicture->render? I have tried it in the classical way (with WM_SIZE- SetScrollSize, WM_HSCROLL and WM_VSCROLL) but it seem that render only renders the portion of DC that is visible. When I scroll a blank portion of image or a blured mix of color is showed.


Thenk you very much for any help s-)

Thank you, vrey interesting indeed but it does not solve ther problem I have. However I found out that IExplore uses the same Interface and has the same problems (you can try yourself).
It seems that it is an internal problem of the IPicture interface

Thanks,
