FeatureRequest: Support showing indices #10

Open jasonf20 opened 6 years ago

jasonf20 commented 6 years ago

allowing printing the indices of the cells would be nice.

If you ever come back to this project and make improvements this could be cool

I don't know if it would be of any use to anybody but I did this to add indices. I'm really new to LaTeX so I did with what I know ... I'm just dropping that here in case anybody in my situation wants something similar: https://github.com/abondis/karnaugh-map/commit/da0bf5e2a7d9443093ef4544bd130d066c942dfc

I've tried a few versions of this. But I'm not really happy with the look of any of them. Taking this off v2.0 for now but leaving this open.

For reference, here are three examples I found online which I think look fine. I notice a few tricks they use to improve the look:

  1. Bigger cell margins / smaller text. The increased margins leave space between cell label, index, and implicant edges with less overlapping and crowding. I think it is ok for some indices to overlap with edges, as the pattern will typically be clear anyway from adjacent cells.
  2. Indices in different color; maybe grey if table is in greyscale.
  3. Implicant edges very close to cell edges; i.e. implicant edges may go either inside index or outside index. Either one works to reduce crowding.

Thanks for the suggestions! That is quite similar to one option that I tried before and wasn't happy about. Therefore I'm currently more in favor of

Maybe an API exposing positions of different parts of the map would be better.

from #5 and let users add the numbering however they like.
