Enumeration Type Documentation

◆ drm_colorop_curve_1d_type

enum drm_colorop_curve_1d_type

enum drm_colorop_curve_1d_type - type of 1D curve

Describes a 1D curve to be applied by the DRM_COLOROP_1D_CURVE colorop.

Enumerator
DRM_COLOROP_1D_CURVE_SRGB_EOTF	@DRM_COLOROP_1D_CURVE_SRGB_EOTF: enum string "sRGB EOTF" sRGB piece-wise electro-optical transfer function. Transfer characteristics as defined by IEC 61966-2-1 sRGB. Equivalent to H.273 TransferCharacteristics code point 13 with MatrixCoefficients set to 0.
DRM_COLOROP_1D_CURVE_SRGB_INV_EOTF	@DRM_COLOROP_1D_CURVE_SRGB_INV_EOTF: enum string "sRGB Inverse EOTF" The inverse of &DRM_COLOROP_1D_CURVE_SRGB_EOTF
DRM_COLOROP_1D_CURVE_PQ_125_EOTF	@DRM_COLOROP_1D_CURVE_PQ_125_EOTF: enum string "PQ 125 EOTF" The PQ transfer function, scaled by 125.0f, so that 10,000 nits correspond to 125.0f. Transfer characteristics of the PQ function as defined by SMPTE ST 2084 (2014) for 10-, 12-, 14-, and 16-bit systems and Rec. ITU-R BT.2100-2 perceptual quantization (PQ) system, represented by H.273 TransferCharacteristics code point 16.
DRM_COLOROP_1D_CURVE_PQ_125_INV_EOTF	@DRM_COLOROP_1D_CURVE_PQ_125_INV_EOTF: enum string "PQ 125 Inverse EOTF" The inverse of DRM_COLOROP_1D_CURVE_PQ_125_EOTF.
DRM_COLOROP_1D_CURVE_BT2020_INV_OETF	@DRM_COLOROP_1D_CURVE_BT2020_INV_OETF: enum string "BT.2020 Inverse OETF" The inverse of &DRM_COLOROP_1D_CURVE_BT2020_OETF
DRM_COLOROP_1D_CURVE_BT2020_OETF	@DRM_COLOROP_1D_CURVE_BT2020_OETF: enum string "BT.2020 OETF" The BT.2020/BT.709 transfer function. The BT.709 and BT.2020 transfer functions are the same, the only difference is that BT.2020 is defined with more precision for 10 and 12-bit encodings.
DRM_COLOROP_1D_CURVE_GAMMA22	@DRM_COLOROP_1D_CURVE_GAMMA22: enum string "Gamma 2.2" A gamma 2.2 power function. This applies a power curve with gamma value of 2.2 to the input values.

DRM_COLOROP_1D_CURVE_COUNT	@DRM_COLOROP_1D_CURVE_COUNT: enum value denoting the size of the enum

Function Documentation

◆ drm_atomic_helper_colorop_duplicate_state()

struct drm_colorop_state * drm_atomic_helper_colorop_duplicate_state ( struct drm_colorop * colorop )

◆ drm_colorop_atomic_destroy_state()

void drm_colorop_atomic_destroy_state	(	struct drm_colorop *	colorop,

◆ drm_colorop_reset()

void drm_colorop_reset ( struct drm_colorop * colorop )

drm_colorop_reset - reset colorop atomic state @colorop: drm colorop

Resets the atomic state for @colorop by freeing the state pointer (which might be NULL, e.g. at driver load time) and allocating a new empty state object.
