Support for `CAIRO_FORMAT_RGB96F` and `CAIRO_FORMAT_RGBA128F`

page200 commented 1 year ago

Cairo offers CAIRO_FORMAT_RGB96F and CAIRO_FORMAT_RGBA128F here: https://gitlab.freedesktop.org/cairo/cairo/-/blob/8f1190dc825ad9ca805c39025dcbcb9aed8b496d/src/cairo.h#L410-411

Please support them in cairo.Format.

That would be crucial for an unbiased restrospective correction of Cairo's incorrect treatment of sRGB.

This does not seam to appear in cairo 1.23 when installing via pip in a docker container (base image python:3.9-slim).

This is a bit over my head and I am not sure if this is even the correct place to ask/tell this. sorry if not, am learning.

Host system; Windows 11, python 3.9

In [8]: cairo.version
Out[8]: '1.23.0'
In [9]: dir(cairo.Format)
Out[9]: 
['A1',
 'A8',
 'ARGB32',
 'INVALID',
 'RGB16_565',
 'RGB24',
 'RGB30',
 'RGB96F',
 'RGBA128F',...

Container; base image: python:3.9-slim

>>> cairo.version
'1.23.0'
>>> dir(cairo.Format)
['A1', 'A8', 'ARGB32', 'INVALID', 'RGB16_565', 'RGB24', 'RGB30', '__abs__',...

Edit: I created its own issue for this, so it might be seen by someone who can point out my error
