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!
There is no palette there, there are 65536 colors possible, but no palette.
So, if you convert it to 24-bit image, colors would be the same.
So if you can extract palette from 24-bit image, you are done 🙂
