VkColorBlendAdvancedEXT(3)

Name

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

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.
