I'm trying to access the width and height dimensions of an NSImage initialized with a JPEG from disk. However, [NSImage size].width and [NSImage size].height is returning strange values. For instance, for a 100 x 200 JPEG the reported width is 1079574528 and height is 0.

Here's some sample code:

NSImage* image = [[NSImage alloc] initWithContentsOfFile: @"my_picture.jpg"];
NSLog(@"Width: %i Height: %i",[image size].width, [image size].height);

And output:

Width: 1079574528 Height: 0

Is [NSImage size] broken or am I just using it incorrectly?

Cheers

I'm not very familiar with all the printf arguments, but what's %i? [image size].width returns a float, so I'd usually use %f. Try that and see if it works; it always has for me.

I think %i is the same as %d, but I'm not sure.
