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;


  • sType is a VkStructureType value identifying this structure.

  • pNext is NULL or a pointer to a structure extending this structure.

  • 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.


Valid Usage (Implicit)
  • VUID-VkTextureLODGatherFormatPropertiesAMD-sType-sType
