Hash
Hash is a unique id indicator just like
--id, but for a asset such as vector & images
Allowed on
- layer with single image fill (a image)
- a vector layer
Use with --main
vector layer 1 --hash=my-brand-logo
vector layer 2 --hash=my-brand-logo --main
Now vector 1 & 2 will use the same svg data, based on vector 2's svg data (since it's marked with --main).
- do - set one layer as main
- don't - set multiple layer with same hash with main (will show warning)
- don't - no main layer specified - will use the first hit item.
