Hi,
we have a problem in our monolithic printer driver with GDI managed
surface…
for a particular application, when printed with a rectangle image,
with ICM profile, drvcopybits is getting called in which we punt back
with EngCopyBits.
EngCopyBits returns TRUE, but doesn’t draw the image correctly…
what would be the possibility for this to go wrong…??
when explicitly returned FALSE, instead of punting back with
EngCopyBits,
DrvStretchBltROP is called to handle the drawing… which draws the
image correctly…
Can somebody throw more light on why this happens…
Thanks,
Shiva P
“Doesn’t draw the image correctly” is not a very distinct description…
Any number of things could go wrong in your punt operation, but most likely
some parameter in your punt-call to EngCopyBits is incorrect… Without
knowing what’s wrong with the picture, it’s hard to say what parameter, or
how it’s wrong…
