Hello, Since the last update, I have continued working on the code that will import JPEG XL image files. So far, it seems I only need to finish a function which takes a stream of data and modifies a "Graphic" to have the data that was decoded from the stream. This function is "ImportJxlGraphic" which is called in vcl/source/filter/graphicfilter.cxx, a file where other image files are also imported.
The libjxl library has some helpful examples on how to use the API, and there is even helpful documentation online (https://libjxl.readthedocs.io/en/latest/api_decoder.html). Seeing how other filetypes, including WebP, are imported in LibreOffice was helpful as well. My implementation so far feels near complete; I'm just working out the particulars of how "Bitmap" and "Graphic" types are used and what the expected format of these types is when importing. This is my latest patchset: https://gerrit.libreoffice.org/c/core/+/208352/2. Thank you, Jesus Solis
