./graphics/babl, Dynamic pixel conversion library

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]

Branch: CURRENT, Version: 0.1.62, Package name: babl-0.1.62, Maintainer: pkgsrc-users

babl is a dynamic, any to any, pixel format translation library.

It allows converting between different methods of storing pixels known
as pixel formats that have with different bitdepths and other data
representations, color models and component permutations.

A vocabulary to formulate new pixel formats from existing primitives is
provided as well as the framework to add new color models and data

Update to 0.1.62

2019-02-01 babl-0.1.62
Continuous integration with gitlab.
Initial CMYK spaces with lcms2 based ICC support, much room for optimization.
Improved custom space support for palette formats.
scRGB space, works like sRGB but always with linear TRCs.
Model introspection API permitting low overhead checks whether a format/model
is RGB, CMYK type of alpha and similar.

Log message:
Need pthread support, make sure a substitue is present if OS lacks support
natively, e.g Minix at present.

Update to 0.1.56

2018-08-14 babl-0.1.56
Improvements to the caching of profiled conversion chains between invocations
by ignoring unknown bits in cache file and remember which conversions yielded
reference fishes.

2018-07-23 babl-0.1.54
Export babl_space_get_icc, babl_space_get, babl_model_with_space,
babl_space_with_trc, babl_format_get_encoding, babl_model_is, SSE2 versions of
YA float and Y float to CIE L float.

Concurrency fixes and fixes to handling of 0/1 entry palettes, do not
pre-equalize XYZ conversion matrices for sRGB, internal clean-ups, pre-define
ACES2065-1 and ACEScg BablSpaces, add R~G~B~ set of spaces, which for all
BablSpaces mean use sRGB TRC.
