# 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.

Loading… please wait.

## 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

- `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. An application-specified value is ignored.

## Description

Valid Usage (Implicit)

- VUID-VkTextureLODGatherFormatPropertiesAMD-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_TEXTURE_LOD_GATHER_FORMAT_PROPERTIES_AMD`
