= Compressed Image Formats
|
|
|
|
|
|
|
|
|
|
The compressed texture formats used by Vulkan are described in the
|
2016-09-17 04:22:17 +00:00
|
|
|
specifically identified sections of the <<data-format,Khronos Data Format
|
2016-02-16 09:53:44 +00:00
|
|
|
Specification>>, version 1.1.
|
|
|
|
|
|
|
|
|
|
Unless otherwise described, the quantities encoded in these compressed
|
|
|
|
|
formats are treated as normalized, unsigned values.

Change log for September 23, 2016 Vulkan 1.0.28 spec update:
* Bump API patch number and header version number to 28 for this update.
Github Issues:
* Minor spelling and typography cleanup, add definitions of
ename:VK_FALSE and ename:VK_TRUE as just what their names say
(public issues 220, 318, 325, 365; internal issues 451, 496)
* Clarify that the pname:maxDescriptorSet limits in the
<<features-limits-required,Required Limits>> table are n *
maxPerStage limit (where n=number of supported stages) (public issue
254).
* Minor cleanup to <<boilerplate-platform-macros,Platform-Specific
Macro Definitions>> appendix (public issue 314).
* Add valid usage statement to slink:VkPipelineLayoutCreateInfo
disallowing multiple push constant ranges for the same shader stage
(public issue 340).
* Clarify the elink:VkSharingMode description of what executing the
"same" barriers means in case of ownership transfer (public issue
347).
* Rename copyright.txt and add COPYING.md to try and reduce confusion
about applicable copyrights (public issue 350).
* Extend the table in the <<boilerplate-wsi-header, Window System-Specific
Header Control>> section to describe the external headers included when
each etext:VK_USE_PLATFORM_* macro is defined (public issue 376).
Internal Issues:
* Add "Revision History" to the PDF outputs following the table of
contents, to match HTML outputs (internal issue 43).
* Clarified that flink:vkMapMemory may fail due to virtual address
space limitations (internal issue 346).
* Add +refBody+ comment markup for ref page autoextraction when required
(internal issue 400).
* Document proper use of "mipmap" and "mip" in the style guide API
naming rules, matching the spelling rules (internal issue 471).
* Tweak the <<extensions,Layers and Extensions>> appendix to note that
the Specification may be built with arbitrary combinations of
extensions (internal issue 483).
* Remove incorrect statement allowing
slink:VkClearAttachment::pname:colorAttachment to be >=
slink:VkSubpassDescription::pname:colorAttachmentCount (internal
issue 488).
* The <<features-limits-viewportboundsrange,viewportBoundsRange>> is
expressed in terms of the pname:maxViewportDimensions but this is
actually two values. Clarify that it's based on the larger of the two
(if they differ) (internal issue 499).
Other Issues:
* Reflowed text of the entire spec using the 'reflow' Makefile gater,
to (hopefully) reduce future internal git churn as edits are made
and extensions added in return for one-time pain. This has no
perceptible change on the spec outputs but considerable changes on
the asciidoc source (internal issue 367).

Those formats listed as sRGB-encoded have in-memory representations of _R_,
|
|
|
|
|
_G_ and _B_ components which are nonlinearly-encoded as latexmath:[$R'$],
|
|
|
|
|
latexmath:[$G'$], and latexmath:[$B'$]; any alpha component is unchanged.
|
|
|
|
|
As part of filtering, the nonlinear latexmath:[$R'$], latexmath:[$G'$], and
|
|
|
|
|
latexmath:[$B'$] values are converted to linear _R_, _G_, and _B_
|
|
|
|
|
components; any alpha component is unchanged.
|
|
|
|
|
The conversion between linear and nonlinear encoding is performed as
|
|
|
|
|
described in the ``KHR_DF_TRANSFER_SRGB'' section of the Khronos Data Format
|
|
|
|
|
Specification.

Change log for March 10, 2016 Vulkan 1.0.6 spec update:
* Bump API patch number and header version number to 6 for this
update.
Github Issues:
* Define 'invocation group' for compute and graphics shaders. Cleanup
definition and use of 'workgroup', and add glossary entries (public
issue 1).
* Various minor editorial fixes (public issue 33).
* Clarify locations for block members in the
<<interfaces-iointerfaces-locations,Location Assignment>>
section (public issue 45).
* Editorial fixes for <<commandbuffer-allocation,Command Buffer
Allocation>> section (public issues 54, 59).
* Clarify behavior of depth test in the <<fragops-depth,Depth
Test>> section (public issues 80, 81).
* Remove discussion of return codes from
flink:vkGetPhysicalDeviceSparseImageFormatProperties and
flink:vkGetImageSparseMemoryRequirements, which don't return values
(public issue 82).
* Allow flink:vkCmdDrawIndirect and flink:vkCmdDrawIndexedIndirect
pname:drawCount of 0, as well as 1, when the multiDrawIndirect
feature is not supported (public issue 88).
* Remove confusing wording in the <<features-limits,Limits>>
section describing the slink:VkPhysicalDeviceLimits
pname:minTexelBufferOffsetAlignment,
pname:minUniformBufferOffsetAlignment, and
pname:minStorageBufferOffsetAlignment members as both minimums and
maximums (public issue 91).
* Clarified that only the RGB components should be affected in places
where sRGB is referred to in the spec, such as ASTC formats. Minor
re-wording to avoid "color space" when actively incorrect, now that
we refer to the Data Format Spec which actually makes a distinction
between color space and transfer function (public issue 94).
* Treat pname:pPropertyCount == 0 consistently in
flink:vkEnumerateInstanceLayerProperties and
flink:vkEnumerateDeviceLayerProperties (public issue 99)
* Cleanup minor editorial issues in chapters 14-17 (public issue 100).
* Clarify definition of flink:vkEnumerateInstanceExtensionProperties
and flink:vkEnumerateDeviceExtensionProperties (public issue 101).
* Define the flink:vkEnumerateInstanceExtensionProperties and
flink:vkEnumerateDeviceExtensionProperties pname:pLayerName
parameter to be a pointer to a null-terminated UTF-8 string (public
issue 101).
* Rearrange "Missing information" references in mandatory format
tables (public issue 101).
* Clarify that the enumerated extensions returned by
flink:vkEnumerateInstanceExtensionProperties and
flink:vkEnumerateDeviceExtensionProperties will only include
extensions provided by the platform or extensions implemented in
implicitly enabled layers (public issue 101).
* Miscellaneous editorial fixes. Include the Vulkan spec patch number
in the PDF title. Fix label on <<fig-non-strict-lines,Non
strict lines>> diagram. Use more easily distinguished symbols in
tables in the <<features-required-format-support,Required
Format Support>> section. Don't require FQDNs used as layer names be
encoded in lower case if not possible, in the
<<extensions-naming-conventions, Extension and Layer Naming
Conventions>> section (public issues 101, 119, 121).
Internal Issues:
* Fixed excessive spacing in tables in XHTML (internal issue 18).
* Clarify that ename:VK_COMMAND_BUFFER_USAGE_ONE_TIME_SUBMIT_BIT
applies to secondary command buffers. Previously spec only referred
to the members of pname:pCommandBuffers being affected by this bit.
Added a separate slink:VkSubmitInfo Valid Usage restriction
specifying that ename:VK_COMMAND_BUFFER_USAGE_ONE_TIME_SUBMIT_BIT
also applies to any secondary command buffers that are recorded into
the primary command buffers in pname:pCommandBuffers (internal issue
106).
* Clarify that slink:VkDeviceCreateInfo::pname:pEnabledFeatures can be
NULL (internal issue 117).
* Remove "the value of" where it is redundant (e.g. speaking of an API
parameter, struct member, or SPIR-V variable, but not when speaking
of color components) (internal issue 175).
* Forced patch version to always be 0 in the header. Add a
"VK_API_VERSION_<major>_<minor>" macro for people to use to do the
right thing. Add a VK_HEADER_VERSION which captures the header
release number independent of the spec patch number (internal issue
176).
* Correct description of
slink:VkPipelineShaderStageCreateInfo::pname:pName to "a pointer to
a null-terminated UTF-8 string" (internal issue #197).
Other Commits:
* Updated DataFormat spec reference to the new date for revision 5 of
that spec.
* Fixed KEEP option (to retain LaTeX intermediate files) in the
Makefile to be included when edited there, as well as set on the
command line.
* Reserve and add "VK_IMG_filter_cubic" to the registry, and implement
script functionality to add and remove validity from existing
functions. Includes schema and readme changes.
* Update GL_KHR_vulkan_glsl so push_constants do not have descriptor
sets.

Change log for March 25, 2016 Vulkan 1.0.7 spec update:
* Bump API patch number and header version number to 7 for this
update.
Github Issues:
* Fix slink:VkSpecializationMapEntry example to avoid C/C++ strict
aliasing issues (public issue 14).
* Clarify the meaning of "matching" in flink:vkCmdBindDescriptorSets
validity language (public issue 33).
* Add stub reference pages so xrefs to not-yet-written pages don't
generate 404 errors. However, the actual content of these pages
still needs to be filled in as time allows (public issue 44, but
does not close that issue out).
* Remove incorrect validity statement for
flink:vkGetImageSparseMemoryRequirements (public issue 85).
* Reword the
<<features-limits-bufferImageGranularity,bufferImageGranularity>>
feature in terms of "aliasing", and clarify that it applies to
bindings in the same memory object (public issue 90).
* Clarify the relationship of the slink:VkPhysicalDeviceLimits
pname:maxViewportDimensions and pname:viewportBoundsRange limits
(public issue 92).
* Specify sparse unbound texture replacement in the
<<textures-texel-replacement,Texel Replacement>> section
independently of robust buffer access language (public issue 100).
* Add the <<fundamentals-architecture-model,Architecture Model>>
section to explain architecture constraints Vulkan has chosen to
accept in order to enable portable and performant code (public issue
122).
* State that an object must not be destroyed until *all* (not *any*)
uses of that object have completed (public issue 123).
* Minor editorial cleanup (public issues 129, 134, 146, 148).
* Add validity language for layer and extension names to
slink:VkDeviceCreateInfo matching that used for
slink:VkInstanceCreateInfo (public issue 130).
* Clean up terminology for the case when the bits set in one bitmask
are a subset of the bits set in another bitmask (public issue 138).
* Document that input attachments are UniformConstant not Input, in
the <<interfaces-inputattachment,Fragment Input Attachment
Interface>> section (public glslang bug 169).
Internal Issues:
* Add max enum values to "flag bits" enums (internal issue #136).
* Clarify language around the various uses of the term "block" in the
<<appendix-compressedtex-bc,Block Compressed Image Formats>> section
(internal issue #202).
* Removed "expand" dependency from <enums> groups in vk.xml and added
auto-generation code in the scripts to infer it instead, to ensure
consistency. This caused renaming of sname:VkColorSpaceKHR and
sname:VkPresentModeKHR etext:BEGIN_RANGE (etc.) tokens, but those
tokens are metadata, not part of the API, and the Vulkan WG is OK
with this change. This change adds ranges to two additional enums
that were missing them due to not defining the "expand" attribute
(internal issue 217).
* Tweak makefile to generate ref page nroff (.3) files in the right
output directory, working around an a2x limitation (internal issue
223).
Other Commits:
* Add validity requirements for flink:vkCmdCopyQueryPoolResults
pname:dstBuffer parameter.
* Fix ref page build to generate .3 targets in the right output
directory.

Change log for September 6, 2016 Vulkan 1.0.26 spec update:
* Bump API patch number and header version number to 26 for this update.
Github Issues:
* Bring sample code in the +VK_KHR_surface+ and +VK_KHR_swapchain+
extension summary appendices up to date, and note they will be replaced
with pointers to the LunarG SDK examples in the future (public issue
279).
* Add a new <<fundamentals-commandsyntax-results-lifetime,Lifetime of
Retrieved Results>> section specifying that ftext:vkGet* and
ftext:VkEnumerate* results are invariant unless otherwise specified, and
specify behavior for individual commands which are not invariant (public
issue 280).
* Remove conflicting definition of
slink:VkDisplayPlaneCapabilitiesKHR::pname:maxSrcPosition and clean up
language of the remaining definition (public issue 351).
* Fix many minor spelling errors and add rules to the style guide to
prevent recurrences (public issue 352).

* Remove redundant descriptions of the etext:VK_USE_PLATFORM_* macros from
the <<wsi,Window System Integration>> chapter in favor of the
description in the <<boilerplate-wsi-header,Window System-Specific
Header Control>> appendix (internal issue 6).
* Replace misleading 'can: be destroyed when not X' with more correct
'must: not be destroyed while X' in the
<<fundamentals-objectmodel-lifetime,Object Lifetime>> section. Disallow
destroying a pipeline layout while a command buffer using it is
recording (internal issue 241).
* Clarify that ename:VK_IMAGE_USAGE_TRANSIENT_ATTACHMENT_BIT is valid for
all images used as attachments in elink:VkImageUsageFlagBits and the
slink:VkImageLayout validity language (internal issue 320).
* Note that <<extended-functionality-layers,Layers>> may wrap object
handles, but that this is a generally discouraged. A link to additional
information in the documentation for layer authors is provided (issue
398)
* Replace the mustnot: and shouldnot: macros with equivalent must: not and
should: not to get rid of non-English words while still highlighting
normative language (internal issue 407).
* Disallow creating multisampled images with
ename:VK_IMAGE_CREATE_CUBE_COMPATIBLE_BIT in the slink:VkImageLayout
validity language and the <<features-supported-sample-counts,Supported
Sample Counts>> section (internal issue 445).
* Fix typo so that flink:vkCmdDrawIndexedIndirect is defined in terms of
flink:vkCmdDrawIndexed rather than flink:vkCmdDrawIndirect (internal
issue 446).
* Reorganize the per-extension information sections to all be in the
<<extensions,Layers & Extensions>> appendix. Also fix a typo in
+VK_IMG_filter_cubic+ which incorrectly identified it as a +KHR+
extension (internal issue 461).
Other Issues:
* Use asciidoc markup instead of latexmath to simplify diagrams in the
<<features-formats-non-packed,byte mapping tables>> for color formats.
* Fix a markup problem with the wildcarded enumerant names in a NOTE in
the <<textures-texel-replacement,Texel Replacement>> section.
* Fix missing attributes in the XML interface for
elink:VkExternalMemoryHandleTypeFlagBitsNV and
elink:VkExternalMemoryFeatureFlagBitsNV (KhronosGroup/Vulkan-Hpp issue
#25)
* Cleanup reference page builds so only core pages are built for releases.

Change log for April 29, 2016 Vulkan 1.0.12 spec update:
* Bump API patch number and header version number to 12 for this
update.
Github Issues:
* Change valid usage statements intended to be "sub-points" to
be actual sub-points (public issue 66).
* Replace double negation in description of
slink:VkRenderPassBeginInfo::pname:pClearValues (based on public
merge 142).
* Cleanup minor typos in spec, ref pages and XML, including those
proposed in public pull requests 144, 150, 151, 167, 168, 181, and
186.
* Use *strict subset* in describing the partial order of memory
property types for slink:VkMemoryType, and update the style guide
accordingly (public issue 190).
* Fix various "a image" -> "an image" typos (public issue 191).
* Note in the <<fundamentals-validusage,Valid Usage>> and
<<extensions-interactions,Extension Interactions>> sections that
structures defined by extensions which may be passed in structure
chains using the ptext:pNext member must: include initial
ptext:sType and ptext:pNext members (public issue 192).
Internal Issues:
* Remove duplicate language from the description of the pname:fence
parameter to flink:vkQueueSubmit and improve validity language
(internal issue 91).
* Added documentation for "optional" attribute to XML readme.tex/pdf
(internal issue 149).
* Clarify the host-side data validity rules and behavior of
flink:vkFlushMappedMemoryRanges and
flink:vkInvalidateMappedMemoryRanges (internal issue 266).
Other Commits:
* Added clarification to flink:vkCmdFillBuffer regarding the use of
ename:VK_WHOLE_SIZE.
* Fixed and documented implementation of "validextensionstructs"
attribute. in XML processing scripts and readme.tex/pdf.
* Add missing validity statements to flink:vkResetEvent and
flink:vkCmdResetEvent.
* Fix validity for the
ename:VK_FORMAT_FEATURE_SAMPLED_IMAGE_FILTER_LINEAR_BIT flag.
Correct all the draw/dispatch commands to mention optimally tiled
images as well as linear tiled images, and say image VIEWS instead
of images. Add validity statement to flink:vkCmdBlitImage
* Replace the {apiname} macro with hardcoded "Vulkan", now that we've
committed to that name.
* Add the VK_AMD_rasterization_order extension to vk.xml.

Change log for March 10, 2016 Vulkan 1.0.6 spec update:
* Bump API patch number and header version number to 6 for this
update.
Github Issues:
* Define 'invocation group' for compute and graphics shaders. Cleanup
definition and use of 'workgroup', and add glossary entries (public
issue 1).
* Various minor editorial fixes (public issue 33).
* Clarify locations for block members in the
<<interfaces-iointerfaces-locations,Location Assignment>>
section (public issue 45).
* Editorial fixes for <<commandbuffer-allocation,Command Buffer
Allocation>> section (public issues 54, 59).
* Clarify behavior of depth test in the <<fragops-depth,Depth
Test>> section (public issues 80, 81).
* Remove discussion of return codes from
flink:vkGetPhysicalDeviceSparseImageFormatProperties and
flink:vkGetImageSparseMemoryRequirements, which don't return values
(public issue 82).
* Allow flink:vkCmdDrawIndirect and flink:vkCmdDrawIndexedIndirect
pname:drawCount of 0, as well as 1, when the multiDrawIndirect
feature is not supported (public issue 88).
* Remove confusing wording in the <<features-limits,Limits>>
section describing the slink:VkPhysicalDeviceLimits
pname:minTexelBufferOffsetAlignment,
pname:minUniformBufferOffsetAlignment, and
pname:minStorageBufferOffsetAlignment members as both minimums and
maximums (public issue 91).
* Clarified that only the RGB components should be affected in places
where sRGB is referred to in the spec, such as ASTC formats. Minor
re-wording to avoid "color space" when actively incorrect, now that
we refer to the Data Format Spec which actually makes a distinction
between color space and transfer function (public issue 94).
* Treat pname:pPropertyCount == 0 consistently in
flink:vkEnumerateInstanceLayerProperties and
flink:vkEnumerateDeviceLayerProperties (public issue 99)
* Cleanup minor editorial issues in chapters 14-17 (public issue 100).
* Clarify definition of flink:vkEnumerateInstanceExtensionProperties
and flink:vkEnumerateDeviceExtensionProperties (public issue 101).
* Define the flink:vkEnumerateInstanceExtensionProperties and
flink:vkEnumerateDeviceExtensionProperties pname:pLayerName
parameter to be a pointer to a null-terminated UTF-8 string (public
issue 101).
* Rearrange "Missing information" references in mandatory format
tables (public issue 101).
* Clarify that the enumerated extensions returned by
flink:vkEnumerateInstanceExtensionProperties and
flink:vkEnumerateDeviceExtensionProperties will only include
extensions provided by the platform or extensions implemented in
implicitly enabled layers (public issue 101).
* Miscellaneous editorial fixes. Include the Vulkan spec patch number
in the PDF title. Fix label on <<fig-non-strict-lines,Non
strict lines>> diagram. Use more easily distinguished symbols in
tables in the <<features-required-format-support,Required
Format Support>> section. Don't require FQDNs used as layer names be
encoded in lower case if not possible, in the
<<extensions-naming-conventions, Extension and Layer Naming
Conventions>> section (public issues 101, 119, 121).
Internal Issues:
* Fixed excessive spacing in tables in XHTML (internal issue 18).
* Clarify that ename:VK_COMMAND_BUFFER_USAGE_ONE_TIME_SUBMIT_BIT
applies to secondary command buffers. Previously spec only referred
to the members of pname:pCommandBuffers being affected by this bit.
Added a separate slink:VkSubmitInfo Valid Usage restriction
specifying that ename:VK_COMMAND_BUFFER_USAGE_ONE_TIME_SUBMIT_BIT
also applies to any secondary command buffers that are recorded into
the primary command buffers in pname:pCommandBuffers (internal issue
106).
* Clarify that slink:VkDeviceCreateInfo::pname:pEnabledFeatures can be
NULL (internal issue 117).
* Remove "the value of" where it is redundant (e.g. speaking of an API
parameter, struct member, or SPIR-V variable, but not when speaking
of color components) (internal issue 175).
* Forced patch version to always be 0 in the header. Add a
"VK_API_VERSION_<major>_<minor>" macro for people to use to do the
right thing. Add a VK_HEADER_VERSION which captures the header
release number independent of the spec patch number (internal issue
176).
* Correct description of
slink:VkPipelineShaderStageCreateInfo::pname:pName to "a pointer to
a null-terminated UTF-8 string" (internal issue #197).
Other Commits:
* Updated DataFormat spec reference to the new date for revision 5 of
that spec.
* Fixed KEEP option (to retain LaTeX intermediate files) in the
Makefile to be included when edited there, as well as set on the
command line.
* Reserve and add "VK_IMG_filter_cubic" to the registry, and implement
script functionality to add and remove validity from existing
functions. Includes schema and readme changes.
* Update GL_KHR_vulkan_glsl so push_constants do not have descriptor
sets.

Change log for March 25, 2016 Vulkan 1.0.7 spec update:
* Bump API patch number and header version number to 7 for this
update.
Github Issues:
* Fix slink:VkSpecializationMapEntry example to avoid C/C++ strict
aliasing issues (public issue 14).
* Clarify the meaning of "matching" in flink:vkCmdBindDescriptorSets
validity language (public issue 33).
* Add stub reference pages so xrefs to not-yet-written pages don't
generate 404 errors. However, the actual content of these pages
still needs to be filled in as time allows (public issue 44, but
does not close that issue out).
* Remove incorrect validity statement for
flink:vkGetImageSparseMemoryRequirements (public issue 85).
* Reword the
<<features-limits-bufferImageGranularity,bufferImageGranularity>>
feature in terms of "aliasing", and clarify that it applies to
bindings in the same memory object (public issue 90).
* Clarify the relationship of the slink:VkPhysicalDeviceLimits
pname:maxViewportDimensions and pname:viewportBoundsRange limits
(public issue 92).
* Specify sparse unbound texture replacement in the
<<textures-texel-replacement,Texel Replacement>> section
independently of robust buffer access language (public issue 100).
* Add the <<fundamentals-architecture-model,Architecture Model>>
section to explain architecture constraints Vulkan has chosen to
accept in order to enable portable and performant code (public issue
122).
* State that an object must not be destroyed until *all* (not *any*)
uses of that object have completed (public issue 123).
* Minor editorial cleanup (public issues 129, 134, 146, 148).
* Add validity language for layer and extension names to
slink:VkDeviceCreateInfo matching that used for
slink:VkInstanceCreateInfo (public issue 130).
* Clean up terminology for the case when the bits set in one bitmask
are a subset of the bits set in another bitmask (public issue 138).
* Document that input attachments are UniformConstant not Input, in
the <<interfaces-inputattachment,Fragment Input Attachment
Interface>> section (public glslang bug 169).
Internal Issues:
* Add max enum values to "flag bits" enums (internal issue #136).
* Clarify language around the various uses of the term "block" in the
<<appendix-compressedtex-bc,Block Compressed Image Formats>> section
(internal issue #202).
* Removed "expand" dependency from <enums> groups in vk.xml and added
auto-generation code in the scripts to infer it instead, to ensure
consistency. This caused renaming of sname:VkColorSpaceKHR and
sname:VkPresentModeKHR etext:BEGIN_RANGE (etc.) tokens, but those
tokens are metadata, not part of the API, and the Vulkan WG is OK
with this change. This change adds ranges to two additional enums
that were missing them due to not defining the "expand" attribute
(internal issue 217).
* Tweak makefile to generate ref page nroff (.3) files in the right
output directory, working around an a2x limitation (internal issue
223).
Other Commits:
* Add validity requirements for flink:vkCmdCopyQueryPoolResults
pname:dstBuffer parameter.
* Fix ref page build to generate .3 targets in the right output
directory.
