Incomplete station name labels when generating transitmap

[jerrywoo96]

To Replicate:

1. Clone loom and cd into loom.
2. Download GTFS data from gtfs_rapid_rail_kl.zip
3. Place gtfs_rapid_rail_kl.zip into ./data.
4. Build docker image docker build -t loom ./.
5. Run interactive shell docker run -v ./data:/data -it loom sh
6. Run the command gtfs2graph /data/gtfs_rapid_rail_kl.zip | loom | transitmap -l > /data/gtfs_rapid_rail_kl.svg in the interactive container shell.
7. Open the generated svg file in ./data/gtfs_rapid_rail_kl.svg on the host machine.
8. Notice that names are incomplete.

Expected:
Correct station names from the actual map

Hi,

I'm having the same issue. It seems like the text is all there but it's an issue with the size of the bounding box is too small for the text.

Yes. Labeling is still experimental. The only reason for this behavior is that it is quite hard to estimate the size of the final rendered text in the SVG, and thus its bounding box. This is done heuristically at the moment, but I experimented with font libraries a while back to read the used font and get its dimensions.

Got the same issue. Oftentimes the last character is cut off.
I'm trying loom on an energy grid where voltage levels are lines, really fun to experiment with.

Workaround is padding with spaces on the labels by the way
