= Copy Commands
|
|
|
|
An application can: copy buffer and image data using several methods
|
|
depending on the type of data transfer.
|
|
Data can: be copied between buffer objects with fname:vkCmdCopyBuffer and a
|
|
portion of an image can: be copied to another image with
|
|
fname:vkCmdCopyImage.
|
|
Image data can: also be copied to and from buffer memory using
|
|
fname:vkCmdCopyImageToBuffer and fname:vkCmdCopyBufferToImage.
|
|
Image data can: be blitted (with or without scaling and filtering) with
|
|
fname:vkCmdBlitImage.
|
|
Multisampled images can: be resolved to a non-multisampled image with
|
|
fname:vkCmdResolveImage.
|
|
|
|
|
|
== Common Operation
|
|
|
|
The following valid usage rules apply to all copy commands:
|
|
|
|
* Copy commands must: be recorded outside of a render pass instance.
|
|
* The set of all bytes bound to all the source regions must: not overlap
|
|
the set of all bytes bound to the destination regions.
|
|
* The set of all bytes bound to each destination region must: not overlap
|
|
the set of all bytes bound to another destination region.
|
|
* Copy regions must: be non-empty.
|
|
* Regions must: not extend outside the bounds of the buffer or image
|
|
level, except that regions of compressed images can: extend as far as
|
|
the dimension of the image level rounded up to a complete compressed
|
|
texel block.
|
|
* Source image subresources must: be in either the
|
|
ename:VK_IMAGE_LAYOUT_GENERAL or
|
|
ename:VK_IMAGE_LAYOUT_TRANSFER_SRC_OPTIMAL layout.
|
|
Destination image subresources must: be in the
|
|
ifdef::VK_KHR_shared_presentable_image[]
|
|
ename:VK_IMAGE_LAYOUT_SHARED_PRESENT_KHR,
|
|
endif::VK_KHR_shared_presentable_image[]
|
|
ename:VK_IMAGE_LAYOUT_GENERAL or
|
|
ename:VK_IMAGE_LAYOUT_TRANSFER_DST_OPTIMAL layout.
|
|
As a consequence, if an image subresource is used as both source and
|
|
destination of a copy, it must: be in the ename:VK_IMAGE_LAYOUT_GENERAL
|
|
layout.
|
|
ifdef::VK_VERSION_1_1,VK_KHR_maintenance1[]
|
|
* Source images must: have ename:VK_FORMAT_FEATURE_TRANSFER_SRC_BIT in
|
|
their <<resources-image-format-features,format features>>.
|
|
* Destination images must: have ename:VK_FORMAT_FEATURE_TRANSFER_DST_BIT
|
|
in their <<resources-image-format-features,format features>>.
|
|
endif::VK_VERSION_1_1,VK_KHR_maintenance1[]
|
|
* Source buffers must: have been created with the
|
|
ename:VK_BUFFER_USAGE_TRANSFER_SRC_BIT usage bit enabled and destination
|
|
buffers must: have been created with the
|
|
ename:VK_BUFFER_USAGE_TRANSFER_DST_BIT usage bit enabled.
|
|
ifndef::VK_EXT_separate_stencil_usage[]
|
|
* Source images must: have been created with
|
|
ename:VK_IMAGE_USAGE_TRANSFER_SRC_BIT set in

|
|
slink:VkImageCreateInfo::pname:usage
|
|
endif::VK_EXT_separate_stencil_usage[]
|
|
ifdef::VK_EXT_separate_stencil_usage[]
|
|
* If the stencil aspect of source image is accessed, and the source image
|
|
was not created with <<VkImageStencilUsageCreateInfoEXT,separate stencil
|
|
usage>>, the source image must: have been created with
|
|
ename:VK_IMAGE_USAGE_TRANSFER_SRC_BIT set in
|
|
slink:VkImageCreateInfo::pname:usage
|
|
* If the stencil aspect of destination image is accessed, and the
|
|
destination image was not created with
|
|
<<VkImageStencilUsageCreateInfoEXT,separate stencil usage>>, the
|
|
destination image must: have been created with
|
|
ename:VK_IMAGE_USAGE_TRANSFER_DST_BIT set in
|
|
slink:VkImageCreateInfo::pname:usage
|
|
* If the stencil aspect of source image is accessed, and the source image
|
|
was created with <<VkImageStencilUsageCreateInfoEXT,separate stencil
|
|
usage>>, the source image must: have been created with
|
|
ename:VK_IMAGE_USAGE_TRANSFER_SRC_BIT set in
|
|
slink:VkImageStencilUsageCreateInfoEXT::pname:stencilUsage
|
|
* If the stencil aspect of destination image is accessed, and the
|
|
destination image was created with
|
|
<<VkImageStencilUsageCreateInfoEXT,separate stencil usage>>, the
|
|
destination image must: have been created with
|
|
ename:VK_IMAGE_USAGE_TRANSFER_DST_BIT set in
|
|
slink:VkImageStencilUsageCreateInfoEXT::pname:stencilUsage
|
|
* If non-stencil aspects of a source image are accessed, the source image
|
|
must: have been created with ename:VK_IMAGE_USAGE_TRANSFER_SRC_BIT set
|
|
in slink:VkImageCreateInfo::pname:usage
|
|
* If non-stencil aspects of a source image are accessed, the source image
|
|
must: have been created with ename:VK_IMAGE_USAGE_TRANSFER_DST_BIT set
|
|
in slink:VkImageCreateInfo::pname:usage
|
|
endif::VK_EXT_separate_stencil_usage[]
|
|
|
|
All copy commands are treated as "`transfer`" operations for the purposes of
|
|
synchronization barriers.

== Copying Data Between Images
|
|
|
|
fname:vkCmdCopyImage performs image copies in a similar manner to a host
|
|
memcpy.
|
|
It does not perform general-purpose conversions such as scaling, resizing,
|
|
blending, color-space conversion, or format conversions.
|
|
Rather, it simply copies raw image data.
|
|
fname:vkCmdCopyImage can: copy between images with different formats,
|
|
provided the formats are compatible as defined below.
|
|
|
|
[open,refpage='vkCmdCopyImage',desc='Copy data between images',type='protos']
|
|
--
|
|
|
|
To copy data between image objects, call:
|
|
|
|
include::{generated}/api/protos/vkCmdCopyImage.txt[]
|
|
|
|
* pname:commandBuffer is the command buffer into which the command will be
|
|
recorded.
|
|
* pname:srcImage is the source image.
|
|
* pname:srcImageLayout is the current layout of the source image
|
|
subresource.
|
|
* pname:dstImage is the destination image.
|
|
* pname:dstImageLayout is the current layout of the destination image
|
|
subresource.
|
|
* pname:regionCount is the number of regions to copy.
|
|
* pname:pRegions is a pointer to an array of slink:VkImageCopy structures
|
|
specifying the regions to copy.
|
|
|
|
Each region in pname:pRegions is copied from the source image to the same
|
|
region of the destination image.
|
|
pname:srcImage and pname:dstImage can: be the same image or alias the same
|
|
memory.
|
|
|
|
[[copies-images-format-compatibility]]
|
|
The formats of pname:srcImage and pname:dstImage must: be compatible.
|
|
Formats are compatible if they share the same class, as shown in the
|
|
<<formats-compatibility,Compatible Formats>> table.
|
|
Depth/stencil formats must: match exactly.
|
|
|
|
ifdef::VK_VERSION_1_1,VK_KHR_sampler_ycbcr_conversion[]
|
|
If the format of pname:srcImage or pname:dstImage is a
|
|
<<formats-requiring-sampler-ycbcr-conversion,_multi-planar_ image format>>,
|
|
regions of each plane to be copied must: be specified separately using the
|
|
pname:srcSubresource and pname:dstSubresource members of the
|
|
slink:VkImageCopy structure.
|
|
In this case, the pname:aspectMask of the pname:srcSubresource or
|
|
pname:dstSubresource that refers to the multi-planar image must: be
|
|
ename:VK_IMAGE_ASPECT_PLANE_0_BIT, ename:VK_IMAGE_ASPECT_PLANE_1_BIT, or
|
|
ename:VK_IMAGE_ASPECT_PLANE_2_BIT.
|
|
For the purposes of fname:vkCmdCopyImage, each plane of a multi-planar image
|
|
is treated as having the format listed in <<formats-compatible-planes>> for
|
|
the plane identified by the pname:aspectMask of the corresponding
|
|
subresource.
|
|
This applies both to elink:VkFormat and to coordinates used in the copy,
|
|
which correspond to texels in the _plane_ rather than how these texels map
|
|
to coordinates in the image as a whole.
|
|
|
|
[NOTE]
|
|
.Note
|
|
====
|
|
For example, the ename:VK_IMAGE_ASPECT_PLANE_1_BIT plane of a
|
|
ename:VK_FORMAT_G8_B8R8_2PLANE_420_UNORM image is compatible with an image
|
|
of format ename:VK_FORMAT_R8G8_UNORM and (less usefully) with the
|
|
ename:VK_IMAGE_ASPECT_PLANE_0_BIT plane of an image of format
|
|
ename:VK_FORMAT_G10X6_B10X6_R10X6_3PLANE_420_UNORM_3PACK16, as each texel is
|
|
2 bytes in size.
|
|

endif::VK_VERSION_1_1,VK_KHR_sampler_ycbcr_conversion[]
|
|
|
|
[[copies-images-format-size-compatibility]]
|
|
fname:vkCmdCopyImage allows copying between _size-compatible_ compressed and
|
|
uncompressed internal formats.
|
|
Formats are size-compatible if the texel block size of the uncompressed
|
|
format is equal to the texel block size of the compressed format.
|
|
Such a copy does not perform on-the-fly compression or decompression.
|
|
When copying from an uncompressed format to a compressed format, each texel
|
|
of uncompressed data of the source image is copied as a raw value to the
|
|
corresponding compressed texel block of the destination image.
|
|
When copying from a compressed format to an uncompressed format, each
|
|
compressed texel block of the source image is copied as a raw value to the
|
|
corresponding texel of uncompressed data in the destination image.
|
|
Thus, for example, it is legal to copy between a 128-bit uncompressed format
|
|
and a compressed format which has a 128-bit sized compressed texel block
|
|
representing 4{times}4 texels (using 8 bits per texel), or between a 64-bit
|
|
uncompressed format and a compressed format which has a 64-bit sized
|
|
compressed texel block representing 4{times}4 texels (using 4 bits per
|
|
texel).
|
|
|
|
When copying between compressed and uncompressed formats the pname:extent
|
|
members represent the texel dimensions of the source image and not the
|
|
destination.
|
|
When copying from a compressed image to an uncompressed image the image
|
|
texel dimensions written to the uncompressed image will be source extent
|
|
divided by the compressed texel block dimensions.
|
|
When copying from an uncompressed image to a compressed image the image
|
|
texel dimensions written to the compressed image will be the source extent
|
|
multiplied by the compressed texel block dimensions.
|
|
In both cases the number of bytes read and the number of bytes written will
|
|
be identical.
|
|
|
|
Copying to or from block-compressed images is typically done in multiples of
|
|
the compressed texel block size.
|
|
For this reason the pname:extent must: be a multiple of the compressed texel
|
|
block dimension.
|
|
There is one exception to this rule which is required: to handle compressed
|
|
images created with dimensions that are not a multiple of the compressed
|
|
texel block dimensions: if the pname:srcImage is compressed, then:
|
|
|
|
* If pname:extent.width is not a multiple of the compressed texel block
|
|
width, then [eq]#(pname:extent.width {plus} pname:srcOffset.x)# must:
|
|
equal the image subresource width.
|
|
* If pname:extent.height is not a multiple of the compressed texel block
|
|
height, then [eq]#(pname:extent.height {plus} pname:srcOffset.y)# must:
|
|
equal the image subresource height.
|
|
* If pname:extent.depth is not a multiple of the compressed texel block
|
|
depth, then [eq]#(pname:extent.depth {plus} pname:srcOffset.z)# must:
|
|
equal the image subresource depth.
|
|
|
|
Similarly, if the pname:dstImage is compressed, then:
|
|
|
|
* If pname:extent.width is not a multiple of the compressed texel block
|
|
width, then [eq]#(pname:extent.width {plus} pname:dstOffset.x)# must:
|
|
equal the image subresource width.
|
|
* If pname:extent.height is not a multiple of the compressed texel block
|
|
height, then [eq]#(pname:extent.height {plus} pname:dstOffset.y)# must:
|
|
equal the image subresource height.
|
|
* If pname:extent.depth is not a multiple of the compressed texel block
|
|
depth, then [eq]#(pname:extent.depth {plus} pname:dstOffset.z)# must:
|
|
equal the image subresource depth.
|
|
|
|
This allows the last compressed texel block of the image in each
|
|
non-multiple dimension to be included as a source or destination of the
|
|
copy.
|
|
|
|
ifdef::VK_VERSION_1_1,VK_KHR_sampler_ycbcr_conversion[]
|
|
"`etext:_422`" image formats that are not

|
<<formats-requiring-sampler-ycbcr-conversion,_multi-planar_>> are treated as

.Note
|
|
====
|
|
To copy both the depth and stencil aspects of a depth/stencil format, two

entries in pname:pRegions can: be used, where one specifies the depth aspect
|
|
in pname:imageSubresource, and the other specifies the stencil aspect.
|
|
====
|
|
|
|
Because depth or stencil aspect buffer to image copies may: require format
|
|
conversions on some implementations, they are not supported on queues that
|
|
do not support graphics.

=== Buffer and Image Addressing
|
|
|
|
Pseudocode for image/buffer addressing of uncompressed formats is:
|
|
|
|
[source,c]
|
|
---------------------------------------------------
|
|
rowLength = region->bufferRowLength;
|
|
if (rowLength == 0)
|
|
rowLength = region->imageExtent.width;
|
|
|
|
imageHeight = region->bufferImageHeight;
|
|
if (imageHeight == 0)
|
|
imageHeight = region->imageExtent.height;
|
|
|
|
texelBlockSize = <texel block size of the format of the src/dstImage>;
|
|
|
|
address of (x,y,z) = region->bufferOffset + (((z * imageHeight) + y) * rowLength + x) * texelBlockSize;
|
|
|
|
where x,y,z range from (0,0,0) to region->imageExtent.{width,height,depth}.
|
|
---------------------------------------------------
|
|
|
|
Note that pname:imageOffset does not affect addressing calculations for
|
|
buffer memory.
|
|
Instead, pname:bufferOffset can: be used to select the starting address in
|
|
buffer memory.
|
|
|
|
For block-compressed formats, all parameters are still specified in texels
|
|
rather than compressed texel blocks, but the addressing math operates on
|
|
whole compressed texel blocks.
|
|
Pseudocode for compressed copy addressing is:
|
|
|
|
[source,c]
|
|
---------------------------------------------------
|
|
rowLength = region->bufferRowLength;
|
|
if (rowLength == 0)
|
|
rowLength = region->imageExtent.width;
|
|
|
|
imageHeight = region->bufferImageHeight;
|
|
if (imageHeight == 0)
|
|
imageHeight = region->imageExtent.height;
|
|
|
|
compressedTexelBlockSizeInBytes = <compressed texel block size taken from the src/dstImage>;
|
|
rowLength /= compressedTexelBlockWidth;
|
|
imageHeight /= compressedTexelBlockHeight;
|
|
|
|
address of (x,y,z) = region->bufferOffset + (((z * imageHeight) + y) * rowLength + x) * compressedTexelBlockSizeInBytes;
|
|
|
|
where x,y,z range from (0,0,0) to region->imageExtent.{width/compressedTexelBlockWidth,height/compressedTexelBlockHeight,depth/compressedTexelBlockDepth}.
|
|
---------------------------------------------------
|
|
|
|
Copying to or from block-compressed images is typically done in multiples of
|
|
the compressed texel block size.
|
|
For this reason the pname:imageExtent must: be a multiple of the compressed
|
|
texel block dimension.
|
|
There is one exception to this rule which is required: to handle compressed
|
|
images created with dimensions that are not a multiple of the compressed
|
|
texel block dimensions:
|
|
|
|
* If pname:imageExtent.width is not a multiple of the compressed texel
|
|
block width, then [eq]#(pname:imageExtent.width {plus}
|
|
pname:imageOffset.x)# must: equal the image subresource width.
|
|
* If pname:imageExtent.height is not a multiple of the compressed texel
|
|
block height, then [eq]#(pname:imageExtent.height {plus}
|
|
pname:imageOffset.y)# must: equal the image subresource height.
|
|
* If pname:imageExtent.depth is not a multiple of the compressed texel
|
|
block depth, then [eq]#(pname:imageExtent.depth {plus}
|
|
pname:imageOffset.z)# must: equal the image subresource depth.
|
|
|
|
This allows the last compressed texel block of the image in each
|
|
non-multiple dimension to be included as a source or destination of the
|
|
copy.

|
|
|
To copy regions of a source image into a destination image, potentially
|
|
performing format conversion, arbitrary scaling, and filtering, call:
|
|
|
|
include::{generated}/api/protos/vkCmdBlitImage.txt[]
|
|
|
|
* pname:commandBuffer is the command buffer into which the command will be
|
|
recorded.
|
|
* pname:srcImage is the source image.
|
|
* pname:srcImageLayout is the layout of the source image subresources for
|
|
the blit.
|
|
* pname:dstImage is the destination image.
|
|
* pname:dstImageLayout is the layout of the destination image subresources
|
|
for the blit.
|
|
* pname:regionCount is the number of regions to blit.
|
|
* pname:pRegions is a pointer to an array of slink:VkImageBlit structures
|
|
specifying the regions to blit.
|
|
* pname:filter is a elink:VkFilter specifying the filter to apply if the
|
|
blits require scaling.
|
|
|
|
fname:vkCmdBlitImage must: not be used for multisampled source or
|
|
destination images.
|
|
Use flink:vkCmdResolveImage for this purpose.
|
|
|
|
As the sizes of the source and destination extents can: differ in any
|
|
dimension, texels in the source extent are scaled and filtered to the
|
|
destination extent.
|
|
Scaling occurs via the following operations:
|
|
|
|
* For each destination texel, the integer coordinate of that texel is
|
|
converted to an unnormalized texture coordinate, using the effective
|
|
inverse of the equations described in
|
|
<<textures-unnormalized-to-integer, unnormalized to integer
|
|
conversion>>:
|
|
:: [eq]#u~base~ = i {plus} {onehalf}#
|
|
:: [eq]#v~base~ = j {plus} {onehalf}#
|
|
:: [eq]#w~base~ = k {plus} {onehalf}#
|
|
* These base coordinates are then offset by the first destination offset:
|
|
:: [eq]#u~offset~ = u~base~ - x~dst0~#
|
|
:: [eq]#v~offset~ = v~base~ - y~dst0~#
|
|
:: [eq]#w~offset~ = w~base~ - z~dst0~#
|
|
:: [eq]#a~offset~ = a - pname:baseArrayCount~dst~#
|
|
* The scale is determined from the source and destination regions, and
|
|
applied to the offset coordinates:
|
|
:: [eq]#scale_u = (x~src1~ - x~src0~) / (x~dst1~ - x~dst0~)#
|
|
:: [eq]#scale_v = (y~src1~ - y~src0~) / (y~dst1~ - y~dst0~)#
|
|
:: [eq]#scale_w = (z~src1~ - z~src0~) / (z~dst1~ - z~dst0~)#
|
|
:: [eq]#u~scaled~ = u~offset~ * scale~u~#
|
|
:: [eq]#v~scaled~ = v~offset~ * scale~v~#
|
|
:: [eq]#w~scaled~ = w~offset~ * scale~w~#
|
|
* Finally the source offset is added to the scaled coordinates, to
|
|
determine the final unnormalized coordinates used to sample from
|
|
pname:srcImage:
|
|
:: [eq]#u = u~scaled~ {plus} x~src0~#
|
|
:: [eq]#v = v~scaled~ {plus} y~src0~#
|
|
:: [eq]#w = w~scaled~ {plus} z~src0~#
|
|
:: [eq]#q = pname:mipLevel#
|
|
:: [eq]#a = a~offset~ {plus} pname:baseArrayCount~src~#
|
|
|
|
These coordinates are used to sample from the source image, as described in
|
|
<<textures, Image Operations chapter>>, with the filter mode equal to that
|
|
of pname:filter, a mipmap mode of ename:VK_SAMPLER_MIPMAP_MODE_NEAREST and
|
|
an address mode of ename:VK_SAMPLER_ADDRESS_MODE_CLAMP_TO_EDGE.
|
|
Implementations must: clamp at the edge of the source image, and may:
|
|
additionally clamp to the edge of the source region.
|
|
|
|
[NOTE]
|
|
.Note
|
|
====
|
|
Due to allowable rounding errors in the generation of the source texture
|
|
coordinates, it is not always possible to guarantee exactly which source
|
|
texels will be sampled for a given blit.
|
|
As rounding errors are implementation dependent, the exact results of a
|
|
blitting operation are also implementation dependent.
|
|
====
|
|
|
|
Blits are done layer by layer starting with the pname:baseArrayLayer member
|
|
of pname:srcSubresource for the source and pname:dstSubresource for the
|
|
destination.
|
|
pname:layerCount layers are blitted to the destination image.
|
|
|
|
3D textures are blitted slice by slice.
|
|
Slices in the source region bounded by pname:srcOffsets[0].pname:z and
|
|
pname:srcOffsets[1].pname:z are copied to slices in the destination region
|
|
bounded by pname:dstOffsets[0].pname:z and pname:dstOffsets[1].pname:z.
|
|
For each destination slice, a source *z* coordinate is linearly interpolated

|
|
If the pname:filter parameter is ename:VK_FILTER_LINEAR then the value
|
|
sampled from the source image is taken by doing linear filtering using the
|
|
interpolated *z* coordinate.
|
|
If pname:filter parameter is ename:VK_FILTER_NEAREST then the value sampled
|
|
from the source image is taken from the single nearest slice, with an
|
|
implementation-dependent arithmetic rounding mode.
|
|
|
|
The following filtering and conversion rules apply:
|
|
|
|
* Integer formats can: only be converted to other integer formats with the
|
|
same signedness.
|
|
* No format conversion is supported between depth/stencil images.
|
|
The formats must: match.
|
|
* Format conversions on unorm, snorm, unscaled and packed float formats of
|
|
the copied aspect of the image are performed by first converting the
|
|
pixels to float values.
|
|
* For sRGB source formats, nonlinear RGB values are converted to linear
|
|
representation prior to filtering.
|
|
* After filtering, the float values are first clamped and then cast to the
|
|
destination image format.
|
|
In case of sRGB destination format, linear RGB values are converted to
|
|
nonlinear representation before writing the pixel to the image.
|
|
|
|
Signed and unsigned integers are converted by first clamping to the
|
|
representable range of the destination format, then casting the value.

If the source formats are floating-point or normalized types, the sample

If the source formats are integer types, a single sample's value is selected

|
|
pname:srcOffset and pname:dstOffset select the initial pname:x, pname:y, and
|
|
pname:z offsets in texels of the sub-regions of the source and destination

|
|
pname:extent is the size in texels of the source image to resolve in

|
Resolves are done layer by layer starting with pname:baseArrayLayer member
