I am trying to extract the palette from a 5-6-5 (16bit) bitmap image that I have produced using ImageConverter Plus from an original Photoshop file. I need to read out the palette and compare it to the palette I have elsewhere for another image.
Is there a piece of freeware (or not) software that can do this? I can read palette files in .pal and .act format with another piece of software, but I would like to generate one of these files from the bitmap in the first place!
Thanks,
George
To add further information:
I start with an 8-bit PNG in Photoshop which uses a pre-defined colour palette which I have already created. This has a maximum of 256 colours in it, and I save this out as a PNG file. I then convert this to a 5-6-5 bitmap in ImageConverter Plus which will scale the R G B values of each colour since in the 8-bit PNG they are defined in terms of 0-255, but obviously in the 5-6-5 bitmap they are defined in 0-31, 0-63, 0-31.
What I want to now do is inspect the values of the 5-6-5 bitmap and basically re-extract a colour palette from it. You can't do this in photoshop as when you open the file again the colours are automatically converted to the 0-255 range. So really, what image program can I use to look at the 0-31 etc... values in my new BMP.
I should explain that the final image is not for display on a PC screen and I appreciate the process is somewhat convulted but that is how it has to be!
