Hi Folks,
I am working on an Cocoa Application whose main purpose is to display
some stuff in OpenGL.
In conjunction with that I need to be able to read in floating point
images (most likely from an exr file) and resize them. Unfortunately,
with NSImage and NSBitmapImage it seems I can get only 32 bpp/8bit per
channel bitmap data (as the example in the cocoa drawing guide).
So I did some research and stumbled upon things like Image I/O, Core
Image and vImage. But I have tom admit have absolutely no clue what to
use when and how.
Can someone probably give me a hint into the right direction? I am
fairly new to OSX development, sometimes kind of confused about all
these frameworks and maybe just not seeing the obvious.
Thanx
Felix
