Restoring the support images: \n png2pdf: \n Without this cache you need to convert png to pdf manualy or you risk a compile timeout (had this problem yesterday and did the conversion manualy. Compile time reduction was from time out to 3sec.)\n env settings required:\n (mount point INSIDE the container)\n CLSI_CACHE_PATH: /var/lib/overleaf/data/cache \n (Mount point outside of the container i.e. host, based on your compose volume rules)\n SANDBOXED_COMPILES_HOST_DIR_CACHE: points to the same folder outside of the container\n Test parameter:\n PNG2PDF_MIN_FILE_SIZE_BYTES: 1024 \n ENABLE_PNG2PDF_CONVERSIONS: true \n PNG2PDF_IMAGE: sharelatex/png2pdf:2026-06-24 \n\n It acts on slow png conversions and not all. Hence the texlive image needs this detection hook as the creator intended it. I added them to:\n https://github.com/davrot/texlive-full/tree/png2pdf-slow \n It is a modification of the LatexMK file. Without the hook no png files are cached as pdf.\n\n pdftocairo: \n The creater intended that pdf to thumbnail / preview are created by an external container for safety reasons. \n The only action we do a to-thumbnail-conversion is in the template generation. Since we don't want to disapoint the creater, I restored this safety feature.\n env settings required:\n (default: local imagemagick; other options are local pdftocairo and container pdftocairo via pdftocairo-sandbox)\n CONVERTER: pdftocairo-sandbox \n CONVERSION_SANDBOX_IMAGE: sharelatex/pdftocairo:24.02 \n (mount point INSIDE the container)\n CONVERSION_SANDBOX_DIR: /var/lib/overleaf/tmp/conversions \n (Mount point outside of the container i.e. host, based on your compose volume rules)\n CONVERSION_SANDBOX_HOST_DIR: points to the same folder outside of the container\n

# Grant the service user access to the Docker socket group, same as the CLSI
# run script. Needed for CONVERTER=pdftocairo-sandbox (filestore launches the
# sibling conversion container through /var/run/docker.sock). Idempotent: a
# fresh container may have no such group yet, and CLSI's run script does the
# same thing, so just append to the membership if it exists.
