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 VkImageFormatProperties2 structure to the pNext chain of the VkPhysicalDeviceImageFormatInfo2 structure and a VkTextureLODGatherFormatPropertiesAMD structure to the pNext chain of the VkImageFormatProperties2 structure.

The VkTextureLODGatherFormatPropertiesAMD structure is defined as:

typedef struct VkTextureLODGatherFormatPropertiesAMD {
    VkStructureType    sType;
    void*              pNext;
    VkBool32           supportsTextureGatherLODBiasAMD;
} VkTextureLODGatherFormatPropertiesAMD;


  • sType is the type of this structure.

  • pNext is NULL.

  • supportsTextureGatherLODBiasAMD tells if the image format can be used with texture gather bias/LOD functions, as introduced by the VK_AMD_texture_gather_bias_lod extension. This field is set by the implementation. User-specified value is ignored.
