VkColorBlendAdvancedEXT

The VkColorBlendAdvancedEXT structure is defined as:

typedef struct VkColorBlendAdvancedEXT {
    VkBlendOp advancedBlendOp;
    VkBool32 srcPremultiplied;
    VkBool32 dstPremultiplied;
    VkBlendOverlapEXT blendOverlap;
    VkBool32 clampResults;
} VkColorBlendAdvancedEXT;

• 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.
