[Feature request] Make SVG arrowheads match the line color #28

Closed holtjma closed 5 months ago

holtjma commented 5 months ago

Hello,

Fairly simple problem: when I generate an SVG image with a directed edge that is some non-black color (e.g., red blue etc.), the arrow head that is generated seems to always be black. I did not see an option to change this via API.

I manually modified the output files and added fill="context-stroke" to each marker and that resolved it, while also allowing for multiple edge colors in the output graph. I hypothesize that it's as simple as modifying the static at this line to resolve this: https://github.com/nadavrot/layout/blob/573248c3fc690650d83bd41fdb1a917676c6dae3/layout/src/backends/svg.rs#L19

Happy to submit a PR myself if it is that simple, but I wasn't sure if there are some non-obvious issues with those changes.
