I am working on a project in MapBox studio where I had to flip all the labels 180° that were on lines. Since its not possible to use text-orientation for labels on lines, I flipped the font file 180 degrees.

I now need to reverse the character strings before they are rendered. Is there a way to do this in MapBox Studio using CartoCSS ?

Something like

direction:rtl;

Where are you sourcing your data from? And are you trying to turn something like abcd into dcba?

If you're sourcing from a PostgreSQL database, there's the reverse() function for strings.

If you're sourcing from a shapefile, it shouldn't be too hard to write a function useing a spreadsheet application (e.g. OpenLibre) that copies one of the columns in the dbf into a new reversed column.

...but to actually answer your question directly: no, I'm pretty sure there is not a way to reverse text using cartocss. sounds like more of a candidate for a data preprocessing step.

  • I am using Mapbox Studio and all the data is coming from the MapBox streets source. If I cannot reverse the Mapbox sourced data then I'll likely have to source my own – jotamon Jan 6 '15 at 18:52
  • Yeah, in that case, you'll have to source your own. – James Conkling Jan 6 '15 at 19:47
