If you execute skp_parser with one argument, it spits out a json representation
of the skp, but that's incomplete since it's missing many binary blobs (these
could represent images or typefaces or just anything that doesn't currently
have a json representation). Each unique blob is labeled with a string in the
form "data/%d". So for example:
tools/git-sync-deps
bin/gn gen out/debug
ninja -C out/debug dm skp_parser
out/debug/dm -m grayscale -w /tmp/dm --config skp
out/debug/skp_parser /tmp/dm/skp/gm/grayscalejpg.skp | less
out/debug/skp_parser /tmp/dm/skp/gm/grayscalejpg.skp | grep data
out/debug/skp_parser /tmp/dm/skp/gm/grayscalejpg.skp data/0 | file -
out/debug/skp_parser /tmp/dm/skp/gm/grayscalejpg.skp data/0 > /tmp/data0.png
"data/0" is an image that the SKP serializer has encoded as PNG.
