…le, partition 23
Section 3.2 explains how formats such as Y'CbCr 4:2:0 are described with _two_ Y' planes under the specification (when other conventional APIs would only use one Y' plane). Table 96...
There are two broken links in the Dataformat 1.3 specification on this page https://www.khronos.org/registry/DataFormat/specs/1.3/dataformat.1.3.html. 1. Near the bottom in this paragrahp: "The international standard for ACES, SMPTE ST 2065-1:2012 -...
Hello 👋 the example DFD for unsigned BC6h in table 48 (around [here](https://www.khronos.org/registry/DataFormat/specs/1.3/dataformat.1.3.html#bc6h_channel), not sure how to link to the actual table) has a `sampleLower` of `0xBF800000U = -1.0f` although...
I am trying to understand how to represent the RGB9E5 format as shown for: - GL : https://www.khronos.org/registry/OpenGL/extensions/EXT/EXT_texture_shared_exponent.txt - VK : https://www.khronos.org/registry/vulkan/specs/1.0/html/vkspec.html#textures-sexp-RGB Note that the conversion to a value is...
As detailed here: https://github.com/KhronosGroup/KTX-Specification/issues/131 It appears that a PVRTC surface must always have at least 2x2=4 data words. Specifically this seems from this: https://github.com/KhronosGroup/KTX-Specification/issues/131#issuecomment-664576977 > From the OpenGL ES `IMG_texture_compression_pvrtc`...
It has two errors. 1. It gives `sampleUpper` as `0x7F800000U` which is NaN (infinity). It should be `0x3F800000U` for 1.0f. 2. It shows it as signed (sign bit set and...
I reported this to you already @fluppeteer but want to record it formally so we don't forget about it. Alexey spotted a conflict between section 5.12 and 5.15. 5.12 shows...
 I believe the second anchor sub 3,2 reference in the first NS=3 case should be 3,3.
asciidoc.py is long obsolete and this gets on a path to incorporate the DF spec into Antora builds. This is working for HTML builds although many of the images are...
