[scribus] Scripting expert needed to speed up colour palette conversion

[José Antonio Rocha]

The whole thing (do the job with SVG imported colors too):

#!/usr/bin/env python
# -*- coding: utf-8 -*-

import sys

try:
    import scribus
except ImportError,err:
    print "This Python script is written for the Scribus scripting
interface."
    print "It can only be run from within Scribus."
    sys.exit(1)

>> Hi all,
>>
>> I have brought on board another commercial colour vendor, this time one
>> from North America. At the moment, we are feverishly working on all sorts
>> of issues, including documentation, colour correctness, logo exchange,
>> licensing etc.

>> You could help to speed up the process by writing a shell or Python

>>
>> I receive all palettes as EPS files, which are easy to convert to
>> Scribus's own XML palette format. However, since the colours aren't stored
>> as spot colours, they end up being imported as something like
>> "FromPDF#00000040", which is completely useless when referring to a printed
>> colour swatch that is based on CMYK ink mixtures.
>>
>> In a Scribus XML palette file, the converted colour entry looks like this:
>>
>> <COLOR NAME="FromPDF#00404040" CMYK="#00404040"/>
>>
>> What is needed is a script that strips the string FromPDF and converts
>> the hex value in a specific way (adding ink channel abbreviations and
>> slashes), so that the end result looks like this:
>>
>> <COLOR NAME="C25/M25/Y25/K25" CMYK="#40404040"/>
>>
>> Anyone willing to step in?
>>
>>
>> Thanks in advance and Happy Easter,
