# VkImageViewMinLodCreateInfoEXT(3) Manual Page

## Name

VkImageViewMinLodCreateInfoEXT - Structure describing the minimum LOD of an image view

Loading… please wait.

## C Specification

The `VkImageViewMinLodCreateInfoEXT` structure is defined as:

    // Provided by VK_EXT_image_view_min_lod
    typedef struct VkImageViewMinLodCreateInfoEXT {
        VkStructureType    sType;
        const void*        pNext;
        float              minLod;
    } VkImageViewMinLodCreateInfoEXT;

## Members

- `sType` is a VkStructureType value identifying this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

- `minLod` is the value to clamp the minimum LOD accessible by this VkImageView.

## Description

If the `pNext` chain includes a `VkImageViewMinLodCreateInfoEXT` structure, then that structure includes a parameter specifying a value to clamp the minimum LOD value during Image Level(s) Selection, Texel Gathering and Integer Texel Coordinate Operations.

If the image view contains `VkImageViewMinLodCreateInfoEXT` and it is used as part of a sampling operation:

minLodFloatimageView = `minLod`

otherwise:

minLodFloatimageView = 0.0

An integer variant of this parameter is also defined for sampling operations which access integer mipmap levels:

minLodIntegerimageView = ⌊minLodFloatimageView⌋

Valid Usage

- VUID-VkImageViewMinLodCreateInfoEXT-minLod-06455
  If the `minLod` feature is not enabled, `minLod` must be `0.0`

- VUID-VkImageViewMinLodCreateInfoEXT-minLod-06456
  `minLod` must be less or equal to the index of the last mipmap level accessible to the view

Valid Usage (Implicit)

- VUID-VkImageViewMinLodCreateInfoEXT-sType-sType
  `sType` must be VK_STRUCTURE_TYPE_IMAGE_VIEW_MIN_LOD_CREATE_INFO_EXT
