20 If you execute skp_parser with one argument, it spits out a json representation
21 of the skp, but that's incomplete since it's missing many binary blobs (these
22 could represent images or typefaces or just anything that doesn't currently
23 have a json representation). Each unique blob is labeled with a string in the
24 form "data/%d". So for example:
25
26 tools/git-sync-deps
27 bin/gn gen out/debug
28 ninja -C out/debug dm skp_parser
29 out/debug/dm -m grayscale -w /tmp/dm --config skp
30 out/debug/skp_parser /tmp/dm/skp/gm/grayscalejpg.skp | less
31 out/debug/skp_parser /tmp/dm/skp/gm/grayscalejpg.skp | grep data
32 out/debug/skp_parser /tmp/dm/skp/gm/grayscalejpg.skp data/0 | file -
33 out/debug/skp_parser /tmp/dm/skp/gm/grayscalejpg.skp data/0 > /tmp/data0.png
34
35 "data/0" is an image that the SKP serializer has encoded as PNG.
