Metadata missing from @startdot diagrams

asked Apr 8 in Bug by coxley

Hey folks! I have tooling written around extracting the metadata from SVG / PNG diagrams. Noticed that they fail for @startdot/@enddot diagrams.

Is that an easy fix? Posting raw SVG of two diagrams to demonstrate below.

@startuml
digraph foo {
  node [style=rounded]
  node1 [shape=box]
}
@enduml

Unfortunately, diagram created by @startdot are managed directly by the dot program.

So we do not have control over it, and we cannot add metadata there.

Sorry about this!
