C Specification
The VkPhysicalDeviceHostImageCopyFeatures
structure is defined as:
// Provided by VK_VERSION_1_4
typedef struct VkPhysicalDeviceHostImageCopyFeatures {
VkStructureType sType;
void* pNext;
VkBool32 hostImageCopy;
} VkPhysicalDeviceHostImageCopyFeatures;
or the equivalent
// Provided by VK_EXT_host_image_copy
typedef VkPhysicalDeviceHostImageCopyFeatures VkPhysicalDeviceHostImageCopyFeaturesEXT;
Members
This structure describes the following feature:
-
sType
is a VkStructureType value identifying this structure. -
pNext
isNULL
or a pointer to a structure extending this structure.
Description
-
hostImageCopy
indicates that the implementation supports copying from host memory to images using the vkCopyMemoryToImage command, copying from images to host memory using the vkCopyImageToMemory command, and copying between images using the vkCopyImageToImage command.
If the VkPhysicalDeviceHostImageCopyFeatures
structure is included in the pNext
chain of the
VkPhysicalDeviceFeatures2 structure passed to
vkGetPhysicalDeviceFeatures2, it is filled in to indicate whether each
corresponding feature is supported.
If the application wishes to use a VkDevice with any features
described by VkPhysicalDeviceHostImageCopyFeatures
, it must add an instance of the structure,
with the desired feature members set to VK_TRUE
, to the pNext
chain of VkDeviceCreateInfo when creating the VkDevice.
