C Specification
If the sampler is created with VK_BORDER_COLOR_FLOAT_OPAQUE_BLACK
,
VK_BORDER_COLOR_INT_OPAQUE_BLACK
,
VK_BORDER_COLOR_FLOAT_CUSTOM_EXT
, or
VK_BORDER_COLOR_INT_CUSTOM_EXT
borderColor
, and that sampler
will be combined with an image view that does not have an
identity swizzle, and
VkPhysicalDeviceBorderColorSwizzleFeaturesEXT::borderColorSwizzleFromImage
is not enabled, then it is necessary to specify the component mapping of the
border color, by including the
VkSamplerBorderColorComponentMappingCreateInfoEXT
structure in the
VkSamplerCreateInfo::pNext
chain, to get defined results.
The VkSamplerBorderColorComponentMappingCreateInfoEXT
structure is
defined as:
// Provided by VK_EXT_border_color_swizzle
typedef struct VkSamplerBorderColorComponentMappingCreateInfoEXT {
VkStructureType sType;
const void* pNext;
VkComponentMapping components;
VkBool32 srgb;
} VkSamplerBorderColorComponentMappingCreateInfoEXT;
Members
-
sType
is the type of this structure. -
pNext
isNULL
or a pointer to a structure extending this structure. -
components
is a VkComponentMapping structure specifying a remapping of the border color components. -
srgb
indicates that the sampler will be combined with an image view that has an image format which is sRGB encoded.
Description
The VkComponentMapping components
member describes a remapping
from components of the border color to components of the vector returned by
shader image instructions when the border color is used.
