C Specification
To determine if texture gather functions that take explicit LOD and/or bias
argument values can be used with a given image format, add a
VkTextureLODGatherFormatPropertiesAMD structure to the pNext
chain of the VkImageFormatProperties2 structure in a call to
vkGetPhysicalDeviceImageFormatProperties2.
The VkTextureLODGatherFormatPropertiesAMD structure is defined as:
// Provided by VK_AMD_texture_gather_bias_lod
typedef struct VkTextureLODGatherFormatPropertiesAMD {
VkStructureType sType;
void* pNext;
VkBool32 supportsTextureGatherLODBiasAMD;
} VkTextureLODGatherFormatPropertiesAMD;
Members
-
sTypeis the type of this structure. -
pNextisNULLor a pointer to a structure extending this structure. -
supportsTextureGatherLODBiasAMDtells if the image format can be used with texture gather bias/LOD functions, as introduced by theVK_AMD_texture_gather_bias_lodextension. This field is set by the implementation. User-specified value is ignored.
