Legacy ImageMagick Discussions Archive

Hello,

I'm a designer needing to find an alternative to the DeBabelizer for creating 8-bit indexed bmp images for digital TV. It would be easier if not for the fact there are some specific requirements around use of colour palettes.

Although I've read a lot of the ImageMagick documentation, I have limited technical expertise and still unsure if ImageMagick can, definitively, generate 8-bit bmp graphics, which:

– allow for transparency (fairly sure this is fine),
– can exclude 16 colours as part of the palette (this part I am less sure of even having read about -remap and quantization).

Any help would be greatly appreciate. Apologies if this is a very basic question. I have searched through the forum.

Thanks,
Andy 

IM can create images that use only colours from a specified "palette". See http://www.imagemagick.org/script/comma ... .php#remap .
Given any input in.png, out.bmp will contain only colours that were in pal.png. pal.png could be an image 1x240 pixels or whatever you want, with just the colours you want.
