0ba1f0af17yapf.js: decodeTexture (container, yapf-sum checks, code books with context decoding, 16-bit / float planes, GPU block tiles), BC1-BC7 / BC6H block decoding and textureToRGBA for display. Matches the C library on 417 generated files (surfaces bit-exact) and survives fuzzing with clean YapfErrors; fixtures in bindings/js/test-data keep it checked. VS Code preview: pickers for mip, face, layer, frame and slice; storage, normal-map convention and version in the info bar. Figma import: textures converted to 8-bit, 8-bit images stay exact.

# YAPF Image Preview for VS Code
|
||
|
||
Click any `.yapf` file in VS Code to see the image.
|
||
|
||
- Checkerboard behind transparent pixels.
|
||
- **Click** to switch between *fit to window* and *100 %*; **Ctrl + scroll**
|
||
to zoom (pixels stay sharp when enlarged).
|
||
- Opens every YAPF file, version 1 and 2: GPU blocks (BC1–BC7, BC6H)
|
||
decoded, 16-bit and float textures shown in 8-bit (floats sRGB encoded).
|
||
- Pickers for **mip level**, cube **face**, array **layer**, animation
|
||
**frame** and volume **slice**.
|
||
- Info bar: size, shape, storage (e.g. *GPU BC7*, *RGB half float*), sRGB /
|
||
linear, normal-map convention, format version, file size, decode time.
|
||
Damaged files say so (checksum mismatch).
|
||
- Reloads automatically when the file changes on disk.
|
||
|
||
Decoding runs in plain JavaScript inside the preview; no native code.
|
||
|
||
## Install
|
||
|
||
- From a release: download `yapf-preview.vsix`, then in VS Code run
|
||
**Extensions: Install from VSIX…** (or `code --install-extension yapf-preview.vsix`).
|
||
- From source (needs Node.js):
|
||
|
||
```sh
|
||
cd extensions/vscode
|
||
npm run package # → yapf-preview-1.0.0.vsix
|
||
code --install-extension yapf-preview-1.0.0.vsix
|
||
```
|
||
|
||
Should work in VS Code 1.75+ and VS Code–based editors such as VSCodium.
|
||
|
||
## Status
|
||
|
||
The `.vsix` packages cleanly, and the preview code was tested in a browser
|
||
engine (headless Chromium) with real files: correct pixels, mip picker,
|
||
error message for corrupt files; the YAPF 2 preview was tested the same
|
||
way (BC7, BC5, BC6H, half float, 16-bit, cube, animation, damaged and
|
||
non-YAPF files). **It has not yet been run inside VS Code itself.**
