◆ dt_iop_gamma_false_color_t

typedef enum dt_iop_gamma_false_color_t dt_iop_gamma_false_color_t

◆ dt_iop_gamma_mask_preview_t

typedef struct dt_iop_gamma_mask_preview_t dt_iop_gamma_mask_preview_t

Shared appearance of mask previews rendered by the display encoding module.

The checker colors remain in linear RGB until they are blended with the image so this path matches module-authored previews that continue through display encoding.

◆ dt_iop_gamma_params_t

typedef struct dt_iop_gamma_params_t dt_iop_gamma_params_t

This module converts float32 RGBA pixels to uint8 BGRA pixels, for GUI pipelines only (darkroom main preview and navigation thumbnail). It self-disables for export pipelines.
