| 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. |
