# Thorium libJXL

      

 - [libjxl](https://github.com/libjxl/libjxl) for Thorium Browser: Restores [JPEG-XL](https://jpegxl.info/) functionality to Thorium/Chromium versions [post M109](https://chromium-review.googlesource.com/c/chromium/src/+/4081749).

 - This repo is added as a submodule to [the main Thorium repo](https://github.com/Alex313031/Thorium), and `setup.sh` therein copies this repos __//src/__ dir over the

 Chromium tree, and then Thorium's __//src/__ dir.

 > @mo271's patch which this is based on: https://chromium-review.googlesource.com/c/chromium/src/+/5454316 \

 https://issues.chromium.org/issues/40256897

 > @gz83's patch which restores jxl devtools functionality: https://chromium-review.googlesource.com/c/devtools/devtools-frontend/+/4257582 (DEPRECATED) \

 > Also related, and needed for building is [libhighway](https://github.com/google/highway)

 – Both libjxl and libhighway versions are bumped to ~ Jun. 2024 revisions. \

 – For info on versions of these and other things, see the [VERSION.md](https://github.com/Alex313031/thorium-libjxl/blob/main/VERSION.md) file \

 – Note that PGO might be slightly less effective unless you generate your own *.profdata* file from a debug build of Thorium/Chromium.

 – __*NOTE:*__ the __//external/__ dir contains two files. These are modified by Thorium and so are excluded from the __//src/__ directory. If you want to integrate libjxl back into a [vanilla Chromium build](https://www.chromium.org), see below.

## Building

#### Thorium Build

 - Simply follow the [normal building procedures](https://github.com/Alex313031/thorium/blob/main/docs/BUILDING.md).

#### Chromium Build

 1. Checkout the Chromium version specified in the [VERSION.md](https://github.com/Alex313031/thorium-libjxl/blob/main/VERSION.md) file.

```bash

# In chromium/src dir #

git checkout -f tags/blahblah # replacing blahblah with the actual tag, i.e. 114.0.5735.134

git clean -ffd # cleans stale or removed dirs

gclient sync --with_branch_heads --with_tags -f -R -D # dont just use 'gclient sync'

```

 2. Run the `./setup.sh` script from within the repo. It assumes the Chromium repo is in *$HOME*, but can be overridden with the __CR_DIR__ env variable.

 3. [Build as normal](https://www.chromium.org/developers/how-tos/get-the-code/)

__NOTE:__ You could also use the *.patch* files with `git am /path/to/patchfile.patch` or `git apply --reject /path/to/patchfile.patch`.
