Extracting from NSImage (NSImageView)

[Andreas Hoeschler]

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
