VkCopyCommandTransformInfoQCOM

The VkCopyCommandTransformInfoQCOM structure is defined as:

typedef struct VkCopyCommandTransformInfoQCOM {
    VkStructureType sType;
    const void* pNext;
    VkSurfaceTransformFlagBitsKHR transform;
} VkCopyCommandTransformInfoQCOM;

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• transform is a VkSurfaceTransformFlagBitsKHR value describing the transform to be applied.

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.
