source: libcaca/trunk/cucul/cucul.h @ 1870

Last change on this file since 1870 was 1870, checked in by Sam Hocevar, 13 years ago
  • Add cucul_get_dither_brightness(), _gamma() and _contrast(). There is no reason to keep a copy of them in the calling program.
  • Deprecate cucul_set_dither_invert(). Inverting a dither's colours is now done by setting a negative gamma value.
