[scribus-dev] python: Pillow?

[dockattt]

yes, to get back to my last post on the Pillow question.  I finally 
found some docs in the manual about the bit depth:

https://pillow.readthedocs.io/en/5.3.x/handbook/concepts.html

"


    Modes

The |mode| of an image defines the type and depth of a pixel in the 
image. The current release supports the following standard modes:

      * |1| (1-bit pixels, black and white, stored with one pixel per byte)
      * |L| (8-bit pixels, black and white)
      * |P| (8-bit pixels, mapped to any other mode using a color palette)
      * |RGB| (3x8-bit pixels, true color)
      * |RGBA| (4x8-bit pixels, true color with transparency mask)
      * |CMYK| (4x8-bit pixels, color separation)
      * |YCbCr| (3x8-bit pixels, color video format)
          o Note that this refers to the JPEG, and not the ITU-R
            BT.2020, standard
      * |LAB| (3x8-bit pixels, the L*a*b color space)
      * |HSV| (3x8-bit pixels, Hue, Saturation, Value color space)
      * |I| (32-bit signed integer pixels)
      * |F| (32-bit floating point pixels)"


    So it doesn't appear that it can go beyond 8 bit pixels except in
    the I and F modes.  So I guess if you had a 16 bit image you'd need
    to write some special code, maybe interact with the I or F modes. ???

Change that name to anything else and Scribus will look to the system for Python -- just make sure it's at least 2.7 or better.
