Maps from BMP using FPGE

The rough steps:
Prepare BMP file using special colors

The each title on map is around 5 pixels. The colors:
{  0,   0, 127}, //dark blue ...  ocean
{  0, 127,   0}, //dark green ... forest
{255, 255, 255}, //white ........ mountains
{255,   0,   0}, //bright red ... road
{  0,   0, 255}, //bright blue ...river
{255, 255,   0}, //yellow ........desert
{  0, 255,   0}, //light green ...clear
{127, 127,   0}, //dark yellow....rough
{127, 127, 127}, //dark grey  ....city
{127,   0,   0}, //dark red   ....bocage
{  0, 127, 127}, //deep cyan  ....swamp

You can use BMP with 8, 24, 32 bites per pixel only.

Run FPGE and use Tools->BMP to Map from menu options

One will get something like this:

Run Tools->Make Tiles

Check layers: terrain and names are all zeros:

Once can choose to fix this using Tools->Generate Layers

The map could be further improved by randomizing tiles:

And the result

 Now is the time to manually fix the map. The Generate Layers step can also be run later. Check help for some more options (shortcut h).
