C Specification
Possible values of the members of VkComponentMapping, specifying the component values placed in each component of the output vector, are:
// Provided by VK_VERSION_1_0
typedef enum VkComponentSwizzle {
VK_COMPONENT_SWIZZLE_IDENTITY = 0,
VK_COMPONENT_SWIZZLE_ZERO = 1,
VK_COMPONENT_SWIZZLE_ONE = 2,
VK_COMPONENT_SWIZZLE_R = 3,
VK_COMPONENT_SWIZZLE_G = 4,
VK_COMPONENT_SWIZZLE_B = 5,
VK_COMPONENT_SWIZZLE_A = 6,
} VkComponentSwizzle;Description
-
VK_COMPONENT_SWIZZLE_IDENTITY specifies that the component is set to the identity swizzle.
-
VK_COMPONENT_SWIZZLE_ZERO specifies that the component is set to zero.
-
VK_COMPONENT_SWIZZLE_ONE specifies that the component is set to either 1 or 1.0, depending on whether the type of the image view format is integer or floating-point respectively, as determined by the Format Definition section for each VkFormat.
-
VK_COMPONENT_SWIZZLE_R specifies that the component is set to the value of the R component of the image.
-
VK_COMPONENT_SWIZZLE_G specifies that the component is set to the value of the G component of the image.
-
VK_COMPONENT_SWIZZLE_B specifies that the component is set to the value of the B component of the image.
-
VK_COMPONENT_SWIZZLE_A specifies that the component is set to the value of the A component of the image.
Setting the identity swizzle on a component is equivalent to setting the identity mapping on that component. That is:
| Component | Identity Mapping |
|---|---|
