good points.
But... um, then how do i fix my imgsize? this nsimage is sometimes coming
from a PDFPage with:
NSData* imgData = [pg dataRepresentation];
NSImage* img = [[NSImage alloc] initWithData:imgData ];
is there a better way to get the data out of the PDFPage?
Other times, it's coming from either a TIFF file, or raw bitmap data from a
scanner.
