Hi,
I have an awful lot of files to convert.
Input is bmp and output should be 800x480, 8bit colour (custom palett -act file-), 71dpi(is this relevant??)
my problem is the custom palett. is there any way I can use this on "convert"??

Re: Convert using Photoshops .act file
Not to my knowledge other than creating an image of those colors and using -remap. See http://www.imagemagick.org/Usage/quantize/#remap. You can add +dither to turn off the dithering.

Re: Convert using Photoshops .act file
Thanks for your answer!
I didnt understand the following:
- remap needs an image using this color table?
- remap needs an image containing all colours that I wish to be used?
I have a bmp file created using this act file. (It does not use the full color space, i guess)
This is how the pallet looks like in photoshop
https://www.dropbox.com/s/587tslzwz1f9tyt/pal_test.bmp
Now the problem is:
when I convert my picture, the size is smaller than expected
-> This works fine. The resulting size is ~1.15Mb
-> The resulting file is only 49kb, instead of 384kb
[/b]
"identify" can read the correct pallette information from the "example_file_with_pallet.bmp" which I have
How can I force 1 byte per pixel and this statical pallett?

Re: Convert using Photoshops .act file
I am not a bmp expert. But try
convert original_picture.bmp -resize 800x480 +dither -remap pal_test.bmp -colors 256 result.bmp
or perhaps the same number of colors in your color map
or perhaps
convert original_picture.bmp -resize 800x480 colors 256 +dither -remap pal_test.bmp -result.bmp
see http://www.imagemagick.org/Usage/formats/#bmp
You may need to use an older format for BMP
convert original_picture.bmp -resize 800x480 +dither -remap pal_test.bmp -depth 8 -type palette BMP3:result.bmp
or BMP2:result.bmp
convert original_picture.bmp -resize 800x480 +dither -remap pal_test.bmp -colors 256 result.bmp
or perhaps the same number of colors in your color map
or perhaps
convert original_picture.bmp -resize 800x480 colors 256 +dither -remap pal_test.bmp -result.bmp
