# VkSubpassSampleLocationsEXT(3) Manual Page

## Name

VkSubpassSampleLocationsEXT - Structure specifying the sample locations state to use for layout transitions of attachments performed after a given subpass

Loading… please wait.

## C Specification

The `VkSubpassSampleLocationsEXT` structure is defined as:

    // Provided by VK_EXT_sample_locations
    typedef struct VkSubpassSampleLocationsEXT {
        uint32_t                    subpassIndex;
        VkSampleLocationsInfoEXT    sampleLocationsInfo;
    } VkSubpassSampleLocationsEXT;

## Members

- `subpassIndex` is the index of the subpass for which the sample locations state is provided.

- `sampleLocationsInfo` is the sample locations state to use for the layout transition of the depth/stencil attachment away from the image layout the attachment is used with in the subpass specified in `subpassIndex`.

## Description

If the image referenced by the depth/stencil attachment used in the subpass identified by `subpassIndex` was not created with `VK_IMAGE_CREATE_SAMPLE_LOCATIONS_COMPATIBLE_DEPTH_BIT_EXT` or if the subpass does not use a depth/stencil attachment, and VkPhysicalDeviceSampleLocationsPropertiesEXT::`variableSampleLocations` is `VK_TRUE` then the values specified in `sampleLocationsInfo` are ignored.

Valid Usage

- `subpassIndex` must be less than the `subpassCount` specified in VkRenderPassCreateInfo the render pass specified by VkRenderPassBeginInfo::`renderPass` was created with

Valid Usage (Implicit)

- `sampleLocationsInfo` must be a valid VkSampleLocationsInfoEXT structure
