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

["Christoph Schäfer"]

Hi José,

Thanks for your effort. Do you think yould also create an extended version of the script that allows for conversion of every Scribus-style import of non-spot colours (e.g. "FromWMF#b8bbab") to something meaningful, so the previously mentioned letter-hex combination becomes "R184/G187/B171"? Such a script would be well worth including in 1.4.3 and 1.5.0.

Required funtions:

- Remove "From[Filetype -- see list of supported formats in the File > Open and File > Import > Get Vector File]".

- Determine the colour space via length of the hex value

- Replace the hex value with decimal values and colour channels divided by slashes: R5/G116/B20, C5/M30/Y40/K10

Cheers,

Christoph
