C Specification
The VkPhysicalDeviceTextureCompressionASTCHDRFeatures structure is
defined as:
// Provided by VK_VERSION_1_3
typedef struct VkPhysicalDeviceTextureCompressionASTCHDRFeatures {
VkStructureType sType;
void* pNext;
VkBool32 textureCompressionASTC_HDR;
} VkPhysicalDeviceTextureCompressionASTCHDRFeatures;// Provided by VK_EXT_texture_compression_astc_hdr
// Equivalent to VkPhysicalDeviceTextureCompressionASTCHDRFeatures
typedef VkPhysicalDeviceTextureCompressionASTCHDRFeatures VkPhysicalDeviceTextureCompressionASTCHDRFeaturesEXT;Members
This structure describes the following feature:
-
sTypeis a VkStructureType value identifying this structure. -
pNextisNULLor a pointer to a structure extending this structure.
Description
-
textureCompressionASTC_HDRindicates whether all of the ASTC HDR compressed texture formats are supported. If this feature is enabled, then the VK_FORMAT_FEATURE_SAMPLED_IMAGE_BIT, VK_FORMAT_FEATURE_BLIT_SRC_BIT and VK_FORMAT_FEATURE_SAMPLED_IMAGE_FILTER_LINEAR_BIT features must be supported inoptimalTilingFeaturesfor the following formats:-
VK_FORMAT_ASTC_12x12_SFLOAT_BLOCK
To query for additional properties, or if the feature is not enabled, vkGetPhysicalDeviceFormatProperties and vkGetPhysicalDeviceImageFormatProperties can be used to check for supported properties of individual formats as normal.
If the VkPhysicalDeviceTextureCompressionASTCHDRFeatures structure is included in the pNext chain of the
VkPhysicalDeviceFeatures2 structure passed to
vkGetPhysicalDeviceFeatures2, it is filled in to indicate whether each
corresponding feature is supported.
If the application wishes to use a VkDevice with any features
described by VkPhysicalDeviceTextureCompressionASTCHDRFeatures, it must add an instance of the structure,
with the desired feature members set to VK_TRUE, to the pNext
chain of VkDeviceCreateInfo when creating the VkDevice.
