I have written a free web-based tool that converts gpx, kml/kmx files to a garmin .img file. You can see it here: https://www.tricktracks.org/

Look at section 4.2.7 at the bottom of page 32 and the table on page 33 of the cgpsmapper manual here, it documents this feature pretty well.

I am not familiar with mkgmap, but would *assume* it would work the same. Have you tried?
For the raster-based maps that I make, I actually created my own icons and generated points along the roads to display them. This was a lot of work, but gives me the control I like. My maps cover relatively small areas however. You can see examples in the screenshots here

This could also be done with Garmin maps if you really want to, but probably not worth the effort.
Regarding cgpsmapper vs mkgmap, I'm still very happy with cgpsmapper and have made some very complex maps with it (also on my website). I don't know what you're trying to do and whether mkgmap would have any advantage. Of course, cgpsmapper is "dead" software so it might make sense to use something that is actively under development. OTOH, Garmin's dedicated GPS devices are also "dying" with fewer models and fewer people purchasing them.

All 3 files should be stored in a folder with a name: Garmin
