- * Color modes that may be supported by a display.
- *
- * Definitions:
- * Rendering intent generally defines the goal in mapping a source (input)
- * color to a destination device color for a given color mode.
- *
- *  It is important to keep in mind three cases where mapping may be applied:
- *  1. The source gamut is much smaller than the destination (display) gamut
- *  2. The source gamut is much larger than the destination gamut (this will
- *  ordinarily be handled using colorimetric rendering, below)
- *  3. The source and destination gamuts are roughly equal, although not
- *  completely overlapping
- *  Also, a common requirement for mappings is that skin tones should be
- *  preserved, or at least remain natural in appearance.
- *
- *  Colorimetric Rendering Intent (All cases):
- *  Colorimetric indicates that colors should be preserved. In the case
- *  that the source gamut lies wholly within the destination gamut or is
- *  about the same (#1, #3), this will simply mean that no manipulations
- *  (no saturation boost, for example) are applied. In the case where some
- *  source colors lie outside the destination gamut (#2, #3), those will
- *  need to be mapped to colors that are within the destination gamut,
- *  while the already in-gamut colors remain unchanged.
- *
- *  Non-colorimetric transforms can take many forms. There are no hard
- *  rules and it's left to the implementation to define.
- *  Two common intents are described below.
- *
- *  Stretched-Gamut Enhancement Intent (Source < Destination):
- *  When the destination gamut is much larger than the source gamut (#1), the
- *  source primaries may be redefined to reflect the full extent of the
- *  destination space, or to reflect an intermediate gamut.
- *  Skin-tone preservation would likely be applied. An example might be sRGB
- *  input displayed on a DCI-P3 capable device, with skin-tone preservation.
- *
- *  Within-Gamut Enhancement Intent (Source >= Destination):
- *  When the device (destination) gamut is not larger than the source gamut
- *  (#2 or #3), but the appearance of a larger gamut is desired, techniques
- *  such as saturation boost may be applied to the source colors. Skin-tone
- *  preservation may be applied. There is no unique method for within-gamut
- *  enhancement; it would be defined within a flexible color mode.
