## Name

VkPhysicalDeviceExternalFormatResolvePropertiesANDROID - Structure describing external format resolve supported by an implementation

Loading… please wait.

## C Specification

The `VkPhysicalDeviceExternalFormatResolvePropertiesANDROID` structure is defined as:

    // Provided by VK_ANDROID_external_format_resolve
    typedef struct VkPhysicalDeviceExternalFormatResolvePropertiesANDROID {
        VkStructureType     sType;
        void*               pNext;
        VkBool32            nullColorAttachmentWithExternalFormatResolve;
        VkChromaLocation    externalFormatResolveChromaOffsetX;
        VkChromaLocation    externalFormatResolveChromaOffsetY;
    } VkPhysicalDeviceExternalFormatResolvePropertiesANDROID;

## Members

- `sType` is a VkStructureType value identifying this structure.

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

- `nullColorAttachmentWithExternalFormatResolve` indicates that there must be no color attachment image when performing external format resolves if it is `VK_TRUE`.

- `externalFormatResolveChromaOffsetX` indicates the VkChromaLocation that an implementation uses in the X axis for accesses to an external format image as a resolve attachment. This must be consistent between external format resolves and load operations from external format resolve attachments to color attachments when `nullColorAttachmentWithExternalFormatResolve` is `VK_TRUE`.

- `externalFormatResolveChromaOffsetY` indicates the VkChromaLocation that an implementation uses in the Y axis for accesses to an external format image as a resolve attachment. This must be consistent between external format resolves and load operations from external format resolve attachments to color attachments when `nullColorAttachmentWithExternalFormatResolve` is `VK_TRUE`.

## Description

If the `VkPhysicalDeviceExternalFormatResolvePropertiesANDROID` structure is included in the `pNext` chain of the VkPhysicalDeviceProperties2 structure passed to vkGetPhysicalDeviceProperties2, it is filled in with each corresponding implementation-dependent property.

Valid Usage (Implicit)

- VUID-VkPhysicalDeviceExternalFormatResolvePropertiesANDROID-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_EXTERNAL_FORMAT_RESOLVE_PROPERTIES_ANDROID`
