Ok am I barking up the wrong tree here?
I know there has to be a way of taking an image of size say 128X128
and drawing it in to a rectangle of say size 256X512
without loosing the aspect ratio of the original image.
However The following code DOES NOT DO THIS
NSImage * screenImage = [[NSImage alloc]initWithCGImage:cgImage
size:NSMakeSize(CGImageGetWidth(cgImage), CGImageGetHeight(cgImage))];
NSImage * destination = [[NSImage alloc]initWithSize:movieFrame.size];
[destination lockFocus];
[[NSColor blackColor]set];
NSRectFill([destination alignmentRect]); //I want a black poster frame
around the image
[screenImage drawInRect:[destination alignmentRect] fromRect:[screenImage
alignmentRect] operation:NSCompositeSourceAtop fraction:1.0];
[destination unlockFocus];
Was I completely mistaken in thinking that the way I'm doing this was suppose
to preserve the aspect ratio?
Is it even possible to do what I'm trying to do? (I know the answer is yes
since I've seen it done.)
Am I going to have to do this at the CGImage level?
Some kind of information would be nice google is a bust, cannot find the
information on the developer site.
All the examples I have seen assume the source and destination images are the
same size
However as I explained before, the user is able to select specific areas in the
capture view to focus on. And since the selections never have the same aspect
ratio as the destination, when I try to draw the image it's distorted.
