Writing grayscale PNGs with a color palette

Recommended Posts

Thanks asbo, :thumbup1: I don't know why I couldn't fond that information...

The problem lies in the fact that these predefined palettes for IMAQ are all 256 element array palettes. A signed 16-bit image (I16) has 65,536 possible values so these will not work with the IMAQ predefined palettes.

Kind of of obvious really, if there aren't enough values in the colour map it won't work. But it's a bit disappointing that this all happens silently without any helpful error messages...

I'll try converting to U8 as the images for presentation rather than analysis.
