pixel size od NSBitmapImageRep

Question

What is the best way to get the size (width and height) of an NSBitmapImageRep?

This is what I'm doing now:

NSBitmapImageRep *bitmap;

NSInteger samplesPerPixel = [bitmap samplesPerPixel];
NSInteger bytesPerPlane = [bitmap bytesPerPlane];
NSInteger bytesPerRow = [bitmap bytesPerRow];
NSInteger numberOfPlanes = [bitmap numberOfPlanes];

NSUInteger numPixels = numberOfPlanes * bytesPerPlane / samplesPerPixel;
NSUInteger width = bytesPerRow / samplesPerPixel;
NSUInteger height = numPixels / width;

Seems like an awful lot of typing for something that should be as easy as [bitmap getWidth]...

I've seen some posts on the internet that query the size like this (this is not in the documentation):

NSSize imageSize = [bitmap size];

But the values don't seem to represent the pixel dimensions of the image (for example, I get a float value of 122.869835 instead of 256, which is the real pixel width of the image).

Answer 1

• [rep pixelsWide]
• [rep pixelsHigh]
