image coloring in image visualizer blow up sometimes does not work

[andrewsu]

For example, the thumbnail visualizer for https://chlambase.org/organism/471472/gene/CTL0370 correctly shows localization to the cell membrane and inclusion body membrane:

But the full sized viewer shows no coloring.

In contrast, both the thumbnail and full-sized views show up fine for https://chlambase.org/organism/471472/gene/CTL0050 (which localizes to EB and RB).

I am not sure what the exact reason is, but I did notice that this bug occurs for all genes with "host cell membrane" as a cc (you can verify this with the advanced search). However, all the other components work (EB. RB, host cell lipid droplets, etc.). The only thing I can think of is that the color of the membranes is done using the "stroke" attribute, whereas the other structures are colored with "fill". If that is indeed the case, then the library that we are using that enhances the image seems to have conflicts with setting the stroke.

Another idea might be that the enlarged image has a different xml structure than the smaller one, so the same paths/attributes might not exist.
