Description

This extension extends adds an optional rotation transform to copy commands cmdBlitImage2KHR, cmdCopyImageToBuffer2KHR and cmdCopyBufferToImage2KHR. When copying between two resources, where one resource contains rotated content and the other does not, a rotated copy may be desired. This extension may be used in combination with VK_QCOM_render_pass_transform which adds rotated render passes.

This extension adds an extension structure to the following commands: vkCmdBlitImage2KHR, vkCmdCopyImageToBuffer2KHR and vkCmdCopyBufferToImage2KHR

Issues

1) What is an appropriate name for the added extension structure? The style guide says “Structures which extend other structures through the pNext chain should reflect the name of the base structure they extend.”, but in this case a single extension structure is used to extend three base structures (vkCmdBlitImage2KHR, vkCmdCopyImageToBuffer2KHR and vkCmdCopyBufferToImage2KHR). Creating three identical structures with unique names seemed undesirable.

RESOLVED: Deviate from the style guide for extension structure naming.

2) Should this extension add a rotation capability to vkCmdCopyImage2KHR?

RESOLVED: No. Use of rotated vkCmdBlitImage2KHR can fully address this use case.

3) Should this extension add a rotation capability to vkCmdResolveImage2KHR?

RESOLVED No. Use of vkCmdResolveImage2KHR is very slow and extremely bandwidth intensive on Qualcomm’s GPU architecture and use of pResolveAttachments in vkRenderPass is the strongly preferred approach. Therefore, we choose not to introduce a rotation capability to vkCmdResolveImage2KHR.

Synopsis

Documentation

data CopyCommandTransformInfoQCOM Source #

VkCopyCommandTransformInfoQCOM - Structure describing transform parameters of rotated copy command

Description

Including this structure in the pNext chain of BufferImageCopy2 defines a rotation to be performed when copying between an image and a buffer. Including this structure in the pNext chain of BlitImageInfo2 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 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 SURFACE_TRANSFORM_IDENTITY_BIT_KHR can only be specified for single-plane 2D images with a 1x1x1 texel block extent.

Bundled Patterns

pattern SURFACE_TRANSFORM_IDENTITY_BIT_KHR :: SurfaceTransformFlagBitsKHR

SURFACE_TRANSFORM_IDENTITY_BIT_KHR specifies that image content is presented without being transformed.

pattern SURFACE_TRANSFORM_ROTATE_90_BIT_KHR :: SurfaceTransformFlagBitsKHR

SURFACE_TRANSFORM_ROTATE_90_BIT_KHR specifies that image content is rotated 90 degrees clockwise.

pattern SURFACE_TRANSFORM_ROTATE_180_BIT_KHR :: SurfaceTransformFlagBitsKHR

SURFACE_TRANSFORM_ROTATE_180_BIT_KHR specifies that image content is rotated 180 degrees clockwise.

pattern SURFACE_TRANSFORM_ROTATE_270_BIT_KHR :: SurfaceTransformFlagBitsKHR

SURFACE_TRANSFORM_ROTATE_270_BIT_KHR specifies that image content is rotated 270 degrees clockwise.

pattern SURFACE_TRANSFORM_HORIZONTAL_MIRROR_BIT_KHR :: SurfaceTransformFlagBitsKHR

SURFACE_TRANSFORM_HORIZONTAL_MIRROR_BIT_KHR specifies that image content is mirrored horizontally.

pattern SURFACE_TRANSFORM_HORIZONTAL_MIRROR_ROTATE_90_BIT_KHR :: SurfaceTransformFlagBitsKHR

SURFACE_TRANSFORM_HORIZONTAL_MIRROR_ROTATE_90_BIT_KHR specifies that image content is mirrored horizontally, then rotated 90 degrees clockwise.

pattern SURFACE_TRANSFORM_HORIZONTAL_MIRROR_ROTATE_180_BIT_KHR :: SurfaceTransformFlagBitsKHR

SURFACE_TRANSFORM_HORIZONTAL_MIRROR_ROTATE_180_BIT_KHR specifies that image content is mirrored horizontally, then rotated 180 degrees clockwise.

pattern SURFACE_TRANSFORM_HORIZONTAL_MIRROR_ROTATE_270_BIT_KHR :: SurfaceTransformFlagBitsKHR

SURFACE_TRANSFORM_HORIZONTAL_MIRROR_ROTATE_270_BIT_KHR specifies that image content is mirrored horizontally, then rotated 270 degrees clockwise.

pattern SURFACE_TRANSFORM_INHERIT_BIT_KHR :: SurfaceTransformFlagBitsKHR

SURFACE_TRANSFORM_INHERIT_BIT_KHR specifies that the presentation transform is not specified, and is instead determined by platform-specific considerations and mechanisms outside Vulkan.
