Hi!

I have the following situation:

I have a folder with ~100 tif files. They have the size 3000x3000 pixel and
256 colors (palette).

I need to give all of them the same palette to merge them (with another
program, not imagemagick).

The images are special data, so only a few colors show up in every file,
like blue, cyan, black - and shadings of this color. But sometimes there are
special symbols in the file in quite another color, like green oder yellow.

So, if I use
convert *.tif -map file1.tif *.tif
the palette is not the same at all in all the files.

If I transfor every file with a single command, like:
convert file1.tif -map file1.tif file1_new.tif
convert file2.tif -map file1.tif file2_new.tif
convert file3.tif -map file1.tif file3_new.tif
...
it works quite well, but if there is none of the special colors in file1.tif
(yellow, green) it will not show up in the right color, if one file uses
this color...

The best posibility would bei the +map option, since I could create ONE
palette from all my files, and then apply it to every file.

But I've failed to get +map to working, so far...

Maybe you could give me a hint (or maybe a solution) how to manage this
problem?

Many Thank!
John
