## C Specification

Possible values of VkPipelineCoverageModulationStateCreateInfoNV::coverageModulationMode, specifying which color components are modulated, are:

// Provided by VK_NV_framebuffer_mixed_samples
typedef enum VkCoverageModulationModeNV {
VK_COVERAGE_MODULATION_MODE_NONE_NV = 0,
VK_COVERAGE_MODULATION_MODE_RGB_NV = 1,
VK_COVERAGE_MODULATION_MODE_ALPHA_NV = 2,
VK_COVERAGE_MODULATION_MODE_RGBA_NV = 3,
} VkCoverageModulationModeNV;

## Description

• VK_COVERAGE_MODULATION_MODE_NONE_NV specifies that no components are multiplied by the modulation factor.

• VK_COVERAGE_MODULATION_MODE_RGB_NV specifies that the red, green, and blue components are multiplied by the modulation factor.

• VK_COVERAGE_MODULATION_MODE_ALPHA_NV specifies that the alpha component is multiplied by the modulation factor.

• VK_COVERAGE_MODULATION_MODE_RGBA_NV specifies that all components are multiplied by the modulation factor.
