My command above works for IM 6.8.9-0, but not 6.8.3-0. The following works for both:
Code: Select all
for /F "usebackq skip=1 tokens=6 delims=():, " %%C ^
in (`convert ^
rose: ^
-unique-colors ^
txt:`) ^
do echo %%C >>x.txt
Remove the unique-colors line if you don't want it. Change "rose:" to any filename.

EDIT: OK, this way it works:
Code: Select all
for /F "usebackq skip=1 tokens=3" %%C ^
in (`%IM%convert ^
rose: ^
-depth 8 ^
txt:`) ^
do echo %%C >>x.txt
findstr # x.txt >> hex.txt
DEL x.txt
This thread can be close
thanks

snibgo will have to comment to be sure. But I am not sure if his code was in .bat format or just for pasting into your CMD window. Try just pasting the following into the CMD window and let us know what you get for the rose: image
Code: Select all
for /F "usebackq skip=1 tokens=3" %%C ^
in (`%IM%convert ^
rose: ^
txt:`) ^
do echo %%C >>x.txt

I should have said: my commands are for BAT format.
If pasting or typing directly into the command window, change "%%C" to "%C" (ie, don't double the percents).

Actually... seems houston is in the house again.
For some reason replacing rose: with my own image seems not to work for whatever reason...
This works (duh.):
Code: Select all
for /F "usebackq skip=1 tokens=3" %%C in (`%IM%convert rose: -depth 8 txt:`) do echo %%C >>x.txt
findstr # x.txt >> hex.txt
However as soon as I
replace rose: with 0001.jpg (f.e.), the script just stops.
Any idea what I'm doing wrong here ?

This also gets the job done, for identifying the hex codes it seems.
Code: Select all
convert img.jpg -unique-colors -depth 8 txt:- > out.txt

How do you know it has stopped? Perhaps it was still working, and you killed it. If your image is large, it will take a long time.

Extracting image colors...
http://www.imagemagick.org/Usage/quantize/#extract
Specifically you either use unique colors, or use the histogram: output format and extract teh image comment.
convert rose: -format %c -depth 8 histogram:info:-
This not only outputs the colors (one color per line), but also the color counts!
