# VkTextureLODGatherFormatPropertiesAMD(3) Manual Page

## Name

VkTextureLODGatherFormatPropertiesAMD - Structure informing whether or not texture gather bias/LOD functionality is supported for a given image format and a given physical device.

## 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;

## Members

- `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 `https://www.khronos.org/registry/vulkan/specs/1.2-extensions/html/vkspec.html#VK_AMD_texture_gather_bias_lod` extension. This field is set by the implementation. User-specified value is ignored.

## Description

Valid Usage (Implicit)

- `sType` must be `VK_STRUCTURE_TYPE_TEXTURE_LOD_GATHER_FORMAT_PROPERTIES_AMD`

## See Also

`VkBool32`, VkStructureType
