C Specification
Bits which can be set in
VkPipelineColorBlendAttachmentState::colorWriteMask
, determining
whether the final color values R, G, B and A are written to the
framebuffer attachment, are:
// Provided by VK_VERSION_1_0
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,
} VkColorComponentFlagBits;
Description
-
VK_COLOR_COMPONENT_R_BIT
specifies 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_BIT
specifies 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_BIT
specifies 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_BIT
specifies 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.
The color write mask operation is applied only if Color Write Enable is enabled for the respective attachment. Otherwise the color write mask is ignored and writes to all components of the attachment are disabled.
