C Specification
The VkImageStencilUsageCreateInfo structure is defined as:
typedef struct VkImageStencilUsageCreateInfo {
VkStructureType sType;
const void* pNext;
VkImageUsageFlags stencilUsage;
} VkImageStencilUsageCreateInfo;
or the equivalent
typedef VkImageStencilUsageCreateInfo VkImageStencilUsageCreateInfoEXT;
Members
-
sTypeis the type of this structure. -
pNextisNULLor a pointer to an extension-specific structure. -
stencilUsageis a bitmask of VkImageUsageFlagBits describing the intended usage of the stencil aspect of the image.
Description
If the pNext chain of VkImageCreateInfo includes a
VkImageStencilUsageCreateInfo structure, then that structure includes
the usage flags specific to the stencil aspect of the image for an image
with a depth-stencil format.
This structure specifies image usages which only apply to the stencil aspect
of a depth/stencil format image.
When this structure is included in the pNext chain of
VkImageCreateInfo, the stencil aspect of the image must only be used
as specified by stencilUsage.
When this structure is not included in the pNext chain of
VkImageCreateInfo, the stencil aspect of an image must only be used
as specified VkImageCreateInfo::usage.
Use of other aspects of an image are unaffected by this structure.
This structure can also be included in the pNext chain of
VkPhysicalDeviceImageFormatInfo2 to query additional capabilities
specific to image creation parameter combinations including a separate set
of usage flags for the stencil aspect of the image using
vkGetPhysicalDeviceImageFormatProperties2.
When this structure is not included in the pNext chain of
VkPhysicalDeviceImageFormatInfo2 then the implicit value of
stencilUsage matches that of
VkPhysicalDeviceImageFormatInfo2::usage.
