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. |
