StretchDiBits fails with SetWorldTransform

[ajay]

Hi,

I am doing SetWorldTransform in a printer DC to rotate the data by 90
degree and scale it by half. But I see that StretchDiBits is unable to
put any data on DC even though it returns the correct number of scan
lines. My DC width, height is 4500,6000. If i dont do the rotation but
keep the scaling then it works. Also if i divide the image in smaller
parts then StretchDuBits works again. Do anyone have any idea why i
have to divide the image while rotating?

Thanks a lot.
Ajay

I am doing SetGraphicsMode(GM_ADVANCED) prior to StretchDiBits.
