VkPipelineCoverageToColorStateCreateInfoNV - Structure specifying whether fragment coverage replaces a color

Description

If the pNext chain of PipelineMultisampleStateCreateInfo includes a PipelineCoverageToColorStateCreateInfoNV structure, then that structure controls whether the fragment coverage is substituted for a fragment color output and, if so, which output is replaced.

If coverageToColorEnable is TRUE, the coverage mask replaces the first component of the color value corresponding to the fragment shader output location with Location equal to coverageToColorLocation and Index equal to zero. If the color attachment format has fewer bits than the coverage mask, the low bits of the sample coverage mask are taken without any clamping. If the color attachment format has more bits than the coverage mask, the high bits of the sample coverage mask are filled with zeros.

If coverageToColorEnable is FALSE, these operations are skipped. If this structure is not present, it is as if coverageToColorEnable is FALSE.

Valid Usage

• If coverageToColorEnable is TRUE, then the render pass subpass indicated by GraphicsPipelineCreateInfo::renderPass and GraphicsPipelineCreateInfo::subpass must have a color attachment at the location selected by coverageToColorLocation, with a Format of FORMAT_R8_UINT, FORMAT_R8_SINT, FORMAT_R16_UINT, FORMAT_R16_SINT, FORMAT_R32_UINT, or FORMAT_R32_SINT

Valid Usage (Implicit)

• sType must be STRUCTURE_TYPE_PIPELINE_COVERAGE_TO_COLOR_STATE_CREATE_INFO_NV

• flags must be 0
