VkCoverageModulationModeNV

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

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;

pub struct CoverageModulationModeNV(u32);
impl CoverageModulationModeNV {
    pub const NONE: Self = 0;
    pub const RGB: Self = 1;
    pub const ALPHA: Self = 2;
    pub const RGBA: Self = 3;
}

• 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.
