Re: Create NSImage from array of integers



 Hi Jason, 

This is a job for Quartz i believe. 

If you know the exact pixel layout and such I'd think you could create a bitmap context and then get the image from that; 

        void* bitmapData = load your array of ints; 
        CGContextRef context = CGBitmapContextCreate(bitmapData, size.width, size.height, bitsPerComponent,  bytesPerRow, CGColorSpaceCreateWithName(kCGColorSpaceGenericGray), kCGImageAlphaNone); 
        image = CGBitmapContextCreateImage(context); 

I think this will work. You might have to tweak some of the args to the context create to get it to draw properly. 

Good Luck,
