C Specification
Bits which can be set in
VkPipelineColorBlendAttachmentState::colorWriteMask to determine
whether the final color values R, G, B and A are written to the
framebuffer attachment are:
typedef enum VkColorComponentFlagBits {
VK_COLOR_COMPONENT_R_BIT = 0x00000001,
VK_COLOR_COMPONENT_G_BIT = 0x00000002,
VK_COLOR_COMPONENT_B_BIT = 0x00000004,
VK_COLOR_COMPONENT_A_BIT = 0x00000008,
VK_COLOR_COMPONENT_FLAG_BITS_MAX_ENUM = 0x7FFFFFFF
} VkColorComponentFlagBits;
Description
-
VK_COLOR_COMPONENT_R_BITspecifies that the R value is written to the color attachment for the appropriate sample. Otherwise, the value in memory is unmodified. -
VK_COLOR_COMPONENT_G_BITspecifies that the G value is written to the color attachment for the appropriate sample. Otherwise, the value in memory is unmodified. -
VK_COLOR_COMPONENT_B_BITspecifies that the B value is written to the color attachment for the appropriate sample. Otherwise, the value in memory is unmodified. -
VK_COLOR_COMPONENT_A_BITspecifies that the A value is written to the color attachment for the appropriate sample. Otherwise, the value in memory is unmodified.
The color write mask operation is applied regardless of whether blending is enabled.
