## Name

VkColorBlendAdvancedEXT - Structure specifying the advanced blend operation parameters for an attachment

Loading… please wait.

## C Specification

The `VkColorBlendAdvancedEXT` structure is defined as:

    // Provided by VK_EXT_extended_dynamic_state3, VK_EXT_shader_object
    typedef struct VkColorBlendAdvancedEXT {
        VkBlendOp            advancedBlendOp;
        VkBool32             srcPremultiplied;
        VkBool32             dstPremultiplied;
        VkBlendOverlapEXT    blendOverlap;
        VkBool32             clampResults;
    } VkColorBlendAdvancedEXT;

## Members

- `advancedBlendOp` selects which blend operation is used to calculate the RGB values to write to the color attachment.

- `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.

- `clampResults` specifies that results must be clamped to the [0,1] range before writing to the attachment, which is useful when the attachment format is not normalized fixed-point.

## Description

Valid Usage

- VUID-VkColorBlendAdvancedEXT-srcPremultiplied-07505
  If the non-premultiplied source color property is not supported, `srcPremultiplied` must be VK_TRUE

- VUID-VkColorBlendAdvancedEXT-dstPremultiplied-07506
  If the non-premultiplied destination color property is not supported, `dstPremultiplied` must be VK_TRUE

- VUID-VkColorBlendAdvancedEXT-blendOverlap-07507
  If the correlated overlap property is not supported, `blendOverlap` must be VK_BLEND_OVERLAP_UNCORRELATED_EXT

Valid Usage (Implicit)

- VUID-VkColorBlendAdvancedEXT-advancedBlendOp-parameter
  `advancedBlendOp` must be a valid VkBlendOp value

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