Image description of molecules changes for different sizes #4517

Closed sfluegel05 closed 1 month ago

sfluegel05 commented 1 month ago

On the ChEBI website, I have noticed some discrepancies between the "normal size" image description of molecules and the "zoomed in" image description. For instance, Alanyl-alanine looks like this in normal size: grafik but changes to this image when zooming in: grafik Note that the "crossed-lines" double bond has become a "parallel-lines" double bond.

Another example would be isotabtoxin (although the differences there are minor).

I have fixed the structure.

We are aware of this issue and this issue mostly likely arises because of indigo, a toolkit that we use in ChEBI which renders structures from text format into images and it doesn't seem to do a good job in some cases. We are currently redeveloping ChEBI and will no longer be using this toolkit.
