Directly instantiate an NSBitmapImageRep with the image-data and call
the method. As to my experience, Cocoa will always use 8-bit RGBA to
display images in an NSImageView.

Hi Folks,
I am trying to get the real number of bits per pixel for a displayed
image.
A NSImageView object enables me to drag n' drop a bmp image from the
Finder
and display it in my app.
Then I got an NSBitmapImageRep from the NSImageView and did that:
int iBitsPerPix = [bittmapImageRep bitsPerPixel];
The result is always 32 even for grayscale 8 bits per pixel images or
24 bits
per pixel color images.
How can I get the image real number of bits per pixel of those images?
Thanks in advance,
Seb
