SVG export contains black layer in background of gene and chromosome tracks

Commit:

• Master branch of higlass
• Compiled version of Danielle’s higlass-multivec
• Compiled version of master branch of higlass-website
• Master branch of higlass-server

Steps to reproduce

1. Add hg38 gene annotations and chromosome tracks
2. Scroll to any spot
3. Export views as SVG

Observed behavior

• Gene and chromosome tracks contain a layer with a black background

Here is a snapshot of what the SVG looks like in Adobe Illustrator CC 22.1:

Notice the selected layer in the Layers palette and the selected rect (or g? — perhaps not as it is labeled as a Path element in Adobe…) element in the SVG.

To view this in a browser, here is a test URL:

http://explorer.altius.org/app/?config=ObkyhPvST7KdrO9J9PNk-g

This test viewconf contains viewport projections; however, closing those viewports to remove them does not change how the SVG is rendered (the track background layers are still rendered black in the SVG).

Expected behavior

• Tracks contain the configured background (white or transparent, if default or not specified in JSON view object)

Should be released soonish. Unless @pkerpedjiev has some more things we could just publish v1.2.4 of the client. Regarding the whole suite, I think we’re just trying to harden the new v1.2 branch which comes with quite a few new additions but it shouldn’t take much longer.

I downloaded it from the link you provided so it’s unrelated to higlass.io but you’re right fill="transparent" is nonsense. I’ll try to fix it
