[mkgmap-dev] How to name islands (are there transparent polygons?)

Sat Jun 26 08:48:38 BST 2010

Some time ago, I added the following translations to the polygons file 
in the default style:

place=island & name=* [0x53 resolution 18]
place=islet & name=* [0x53 resolution 20]

Before this addition, islands were not named on the map. The polygon 
style is documented like this in resources/garmin_feature_list.csv:

polygon|0x80|0x53||flats||Flatland

One paddler complained to me that the named islands look different (and 
harder to distinguish from water) than unnamed islands. I believe that 
the unnamed islands would be "empty background", rendered in the Garmin 
yellow (or black in night mode). Are there any transparent polygon types 
that could be used for naming islands? How do paid-for Garmin maps 
represent islands?
