Hi folks,
could someone clarify for me how I can get the data range of a given image? For instance, I have an image that ranges in colour values from 0-65535. How can I test for this data value range programmatically? I'm needing to get which data range the images are in, i.e. are they 0-255, 0-65535, 0.0-1.0.
Cheers,
WP.

255 = 8 bits
65535 = 16 bits
float = 32 bits "and it can go out of range (0.f - 1.f)"
BaseBitmap yourBitmap = ...;
Int32 bits = yourBitmap.GetBt();

Hi Mohammed,
that's what I thought. I'd been using COLORMODE to get the mode flag, but an experiment I ran was giving me an image with 0-65535 an 8 bit data range. It must be something else. I'll need to keep digging.
Thanks,
WP.

Hi,
I think, GetBt() is more what you'll want.
There's also a Python example script, how to use it in the Python SDK examples: Copy32BitImage.py
It should be easily transferable to C++.
