Hi all,
say I have an NSImage with size {1024, 1024 } created from a TIFF or
from PDF data. I created an imageView of the same size and composite
the image.I would like to create a new image by extracting the rect
{100,100, 640, 480} from the imageView I tried to do that with
NSData *result = [imageView dataWithPDFInsideRect:subFrame];
where subFrame = {100,100, 640, 480}, However, this give me not the
portion of the image I requested but the whole image with big white
margins. I encounered this behaviour on Cocoa (haven't checked GNUstep
so far). Is this a bug in Coco or have I misunderstood the meaning on
this method?
Thanks a lot!
Regards,
Andreas
