[mkgmap-dev] Background Fill Polygon

Thu Jun 11 21:25:06 BST 2009

Etrex and Gpsmaps units (maybe others too) display the map background in 
yellow, this is not good for contrast and makes reading the display 
difficult while in forest or other places with quickly changing light 
conditions between sun/shadow. One can define 0x4b polygon color in 
typfile, with white or greay to remedy the situation. However this makes 
the gps draw the background twice and reduces performance when scrolling 
the map.
Would it be possible to have mkgmap fill up any area where there is no 
polygon defined? It should be customizable which polygon to map instead 
(0x01 would probabely work well for people not using typfiles). It 
simply should not be 0x4a or 0x4b.
