## Name

VkPipelineColorBlendAdvancedStateCreateInfoEXT - Structure specifying parameters that affect advanced blend operations

Loading… please wait.

## C Specification

If the `pNext` chain of VkPipelineColorBlendStateCreateInfo includes a `VkPipelineColorBlendAdvancedStateCreateInfoEXT` structure, then that structure includes parameters that affect advanced blend operations.

The `VkPipelineColorBlendAdvancedStateCreateInfoEXT` structure is defined as:

    // Provided by VK_EXT_blend_operation_advanced
    typedef struct VkPipelineColorBlendAdvancedStateCreateInfoEXT {
        VkStructureType      sType;
        const void*          pNext;
        VkBool32             srcPremultiplied;
        VkBool32             dstPremultiplied;
        VkBlendOverlapEXT    blendOverlap;
    } VkPipelineColorBlendAdvancedStateCreateInfoEXT;

## Members

- `sType` is the type of this structure.

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

- `srcPremultiplied` specifies whether the source color of the blend operation is treated as premultiplied.

- `dstPremultiplied` specifies whether the destination color of the blend operation is treated as premultiplied.

- `blendOverlap` is a VkBlendOverlapEXT value specifying how the source and destination sample’s coverage is correlated.

## Description

If this structure is not present, `srcPremultiplied` and `dstPremultiplied` are both considered to be `VK_TRUE`, and `blendOverlap` is considered to be `VK_BLEND_OVERLAP_UNCORRELATED_EXT`.

Valid Usage

- VUID-VkPipelineColorBlendAdvancedStateCreateInfoEXT-srcPremultiplied-01424
  If the non-premultiplied source color property is not supported, `srcPremultiplied` must be `VK_TRUE`

- VUID-VkPipelineColorBlendAdvancedStateCreateInfoEXT-dstPremultiplied-01425
  If the non-premultiplied destination color property is not supported, `dstPremultiplied` must be `VK_TRUE`

- VUID-VkPipelineColorBlendAdvancedStateCreateInfoEXT-blendOverlap-01426
  If the correlated overlap property is not supported, `blendOverlap` must be `VK_BLEND_OVERLAP_UNCORRELATED_EXT`

Valid Usage (Implicit)

- VUID-VkPipelineColorBlendAdvancedStateCreateInfoEXT-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PIPELINE_COLOR_BLEND_ADVANCED_STATE_CREATE_INFO_EXT`

- VUID-VkPipelineColorBlendAdvancedStateCreateInfoEXT-blendOverlap-parameter
  `blendOverlap` must be a valid VkBlendOverlapEXT value
