IDDCX_TARGET_CAPS enumeration (iddcx.h)

  • Article

An IDDCX_TARGET_CAPS enumeration value identifies the capabilities of a target.

Syntax

typedef enum IDDCX_TARGET_CAPS {
  IDDCX_TARGET_CAPS_NONE = 0,
  IDDCX_TARGET_CAPS_WIDE_COLOR_SPACE = 0x1,
  IDDCX_TARGET_CAPS_HIGH_COLOR_SPACE = 0x2
} ;

Constants

 
IDDCX_TARGET_CAPS_NONE
Value: 0
The target doesn't support any of the available capabilities.
IDDCX_TARGET_CAPS_WIDE_COLOR_SPACE
Value: 0x1
If set, the driver has the ability to transform RGB values from the gamut defined by the sRGB/709 primaries to the monitor's primaries. The driver can also send any necessary control signaling to the monitor to indicate the correct interpretation of the pixel data being sent. This includes handling signed input in the range (-2.0 to 2.0). The driver must do this with all supported input surface formats, including 8888 and FP16.
IDDCX_TARGET_CAPS_HIGH_COLOR_SPACE
Value: 0x2
If set, the driver supports all of the above WideColorSpace gamut functionality and also has the ability to apply the appropriate transfer curve for that display. This means accepting canonical color space data in the range [-128.0 to 256.0] and sending any necessary control signaling to the connected display to indicate the correct interpretation.

Setting IDDCX_TARGET_CAPS_HIGH_COLOR_SPACE is not a replacement for setting IDDCX_TARGET_CAPS_WIDE_COLOR_SPACE. Drivers that support IDDCX_TARGET_CAPS_HIGH_COLOR_SPACE should also set IDDCX_TARGET_CAPS_WIDE_COLOR_SPACE.

Remarks

For more information about HDR support, see IddCx version 1.10 updates.
