Hello,

I created a CGContext based on a raw surface I allocated by self:

 FContext := CGBitmapContextCreate(FBits,
  NewWidth, NewHeight, 8, Stride, FColorSpace,
kCGImageAlphaNoneSkipFirst or kCGBitmapByteOrder32Little);

Then I would use this FContext to perform some drawing operations.
Now, I would like to draw part of this area into another CGContext,
with stretching and also without. How can this be done?

I couldn't find a function to simply copy an area from a CGContext
into another one.

I have access to the pointer where the bits are located.

thanks,
