# VkPhysicalDeviceBlendOperationAdvancedPropertiesEXT(3) Manual Page

## Name

VkPhysicalDeviceBlendOperationAdvancedPropertiesEXT - Structure describing advanced blending limits that can be supported by an implementation

## C Specification

The `VkPhysicalDeviceBlendOperationAdvancedPropertiesEXT` structure is defined as:

    typedef struct VkPhysicalDeviceBlendOperationAdvancedPropertiesEXT {
        VkStructureType    sType;
        void*              pNext;
        uint32_t           advancedBlendMaxColorAttachments;
        VkBool32           advancedBlendIndependentBlend;
        VkBool32           advancedBlendNonPremultipliedSrcColor;
        VkBool32           advancedBlendNonPremultipliedDstColor;
        VkBool32           advancedBlendCorrelatedOverlap;
        VkBool32           advancedBlendAllOperations;
    } VkPhysicalDeviceBlendOperationAdvancedPropertiesEXT;

## Members

The members of the `VkPhysicalDeviceBlendOperationAdvancedPropertiesEXT` structure describe the following implementation-dependent limits:

## Description

- `sType` is the type of this structure.

- `pNext` is `NULL` or a pointer to an extension-specific structure.

- `advancedBlendMaxColorAttachments` is one greater than the highest color attachment index that can be used in a subpass, for a pipeline that uses an advanced blend operation.

- `advancedBlendIndependentBlend` specifies whether advanced blend operations can vary per-attachment.

- `advancedBlendNonPremultipliedSrcColor` specifies whether the source color can be treated as non-premultiplied. If this is `VK_FALSE`, then VkPipelineColorBlendAdvancedStateCreateInfoEXT::`srcPremultiplied` must be `VK_TRUE`.

- `advancedBlendNonPremultipliedDstColor` specifies whether the destination color can be treated as non-premultiplied. If this is `VK_FALSE`, then VkPipelineColorBlendAdvancedStateCreateInfoEXT::`dstPremultiplied` must be `VK_TRUE`.

- `advancedBlendCorrelatedOverlap` specifies whether the overlap mode can be treated as correlated. If this is `VK_FALSE`, then VkPipelineColorBlendAdvancedStateCreateInfoEXT::`blendOverlap` must be `VK_BLEND_OVERLAP_UNCORRELATED_EXT`.

- `advancedBlendAllOperations` specifies whether all advanced blend operation enums are supported. See the valid usage of VkPipelineColorBlendAttachmentState.

If the `VkPhysicalDeviceBlendOperationAdvancedPropertiesEXT` structure is included in the `pNext` chain of VkPhysicalDeviceProperties2, it is filled with the implementation-dependent limits.

Valid Usage (Implicit)

- `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_BLEND_OPERATION_ADVANCED_PROPERTIES_EXT`
