convert your colormap into an image, one block (any size) of pixels for each color, then use -remap to apply it to your image.

see http://www.imagemagick.org/script/comma ... .php#remap and http://www.imagemagick.org/Usage/quantize/#web_safe (but use your image rather than the netscape one and use -remap rather than -map, actually both are the same)


Here is how I generated the CSS 140 color palette

This produces one row of colors (very wide image). If you are clever you can do a double loop and make a square image of multiple rows (16x16 rows for 256 colors)

[anthony]

This produces one row of colors (very wide image). If you are clever you can do a double loop and make a square image of multiple rows (16x16 rows for 256 colors)

Alternativeally you can create each image and feed it into montage to generate an array of colors.

The intermediate image is then replaced by a pipeline!

Code: Select all

for color in $colors; do
   echo >&2 "$i $color"
   convert -size 10x10 xc:"$color" miff:-
   i=$(($i + 1))
done | montage - -tile 14x10 -geometry +0+0 csspalette.png

Note that the "echo" was modified to output to standard error and not standard output which is being used to output a stream of small 10x10 images (MIFF all concatenated together)

Fred what is the 140 CSS image for?

Steej: As you already have the colors in a format that is very close to a IM Enumerated image format. It would not take a lot of editing (with a good text editor) to turn it into that image file format. See... http://www.imagemagick.org/Usage/files/#txt

The CCS image was for a client who wanted to color reduce some images via -remap into those colors. The row format was my first cut. I actually put into grid format of 7 rows of 20 colors.

With regard to the txt: format, Anthony, can you use that format with -remap? I had not even considered that.

Fred

[anthony]

Remap reads ANY image! It just extracts the colors for the the dithering stage.

Technically it is just the dither side of the -colors quantization command.

[steej]

wow, i didn't expect these wonderful answers. thank you

ok, fred's script works well, but I need the same colormap (exactly the same!)
this is the new colormap

there are less colour (last 5 are blacks) and the order isn't preserved.

I know, this is a stupid request, but I've a program that open only bitmap file with this colormap.

@anthony: i will try to create directly the txt image, thank you.

you must have skipped five entries in your list to get the last few as black. did you use rgb(...) values (or color names or hex values). Either should be fine. Just don't use the (...) raw values.

It might be easier to read the values in from a file (using cat) rather than making them into one long string. It is easy to miss something when making a long string. With a file, you can see exactly how many lines you have.

[steej]

the echo command of your script shows 255 color and the palette image created seems correct ...
I will check it more carefully ...

[fmw42]

perhaps you reached some character limit in the string of colors on your system?

[steej]

I have discovered that the compatibility problem with my program wasn't colormap but the bmp compression

I've resolved by

Code: Select all

mogrify -compression None filename.bmp

thank you for all

[Drarakel]

Maybe it was also due to ImageMagick's special format of the RLE compression. (See my report here.)
Could you provide your first version of the BMP file (the compressed one) - or the command that created it?

[steej]

this is the image
http://rapidshare.com/files/403353976/fontain.bmp.html

download from internet and modified by imagemagick

Code: Select all

mogrify -units PixelsPerInch -resize 27x27! -density 72 -colors 256 fontain.bmp

I discovered the problem making the same procedure with GIMP and disabling the RLE compression.

[Drarakel]

OK. Thanks!

Hmm.. But the 'fontain.bmp' file only has 105 colors - and in the palette are only 115 colors, apart from black.
So, I'm not sure how you got the palette from your first post...
And then this palette:

ok, fred's script works well, but I need the same colormap (exactly the same!)
this is the new colormap
...

I hope I don't bug you.

Do you have the same problem using your BMP files when writing it with Gimp - with enabled RLE compression?

[steej]

Do you have the same problem using your BMP files when writing it with Gimp - with enabled RLE compression?

yes.
may be it is not related to the bug

[Drarakel]

Seems to be the case, yes. Thanks for clarifying!
