C Specification
The VkCopyCommandTransformInfoQCOM
structure is defined as:
// Provided by VK_QCOM_rotated_copy_commands
typedef struct VkCopyCommandTransformInfoQCOM {
VkStructureType sType;
const void* pNext;
VkSurfaceTransformFlagBitsKHR transform;
} VkCopyCommandTransformInfoQCOM;
Members
-
sType
is a VkStructureType value identifying this structure. -
pNext
isNULL
or a pointer to a structure extending this structure. -
transform
is a VkSurfaceTransformFlagBitsKHR value describing the transform to be applied.
Description
Including this structure in the pNext
chain of
VkBufferImageCopy2 defines a rotation to be performed when copying
between an image and a buffer.
Including this structure in the pNext
chain of VkBlitImageInfo2
defines a rotation to be performed when blitting between two images.
If this structure is not specified in either case, the implementation
behaves as if it was specified with a transform
equal to
VK_SURFACE_TRANSFORM_IDENTITY_BIT_KHR
.
Specifying a transform for a copy between an image and a buffer rotates the region accessed in the image around the offset. Specifying a transform for a blit performs a similar transform as described in Image Blits with Scaling and Rotation.
Rotations other than VK_SURFACE_TRANSFORM_IDENTITY_BIT_KHR
can only
be specified for single-plane 2D images with a 1x1x1
texel block extent.
