Change arrow appearance in Canvas track

[jelleslager]

Hi,

I wanted to change the colour (and if possible also the length) of the arrows indicating the direction of features in a Canvas track. I tried modifying the files '[plus/minus]-arrowhead.png', but it seems this is only used for HTML tracks. I couldn't discover from where Canvas tracks get their parts. Any ideas on this?

Thanks!

Hi Jelle, The arrowheads for Canvas are embedded in code. Yuk, but here they are: https://github.com/GMOD/jbrowse/blob/dev/src/JBrowse/View/FeatureGlyph/Box.js#L151
