Can also dynamically run this by passing an array on the command line:
/Applications/OpenSCAD.app/Contents/MacOS/OpenSCAD -m make -D bitmap=[2,2,2,0,1,3,2,2,2] -D row_size=3 -s height_map.stl height_map.scad
*/
use <bitmap.scad>
block_size = 5;
height = 5;
row_size = 10; // 10x10 pixels
bitmap = [
1,1,0,0,1,1,0,0,1,1,
1,1,1,1,1,1,1,1,1,1,
0,1,2,2,1,1,2,2,1,0,
0,1,2,1,1,1,1,2,1,0,
1,1,1,1,3,3,1,1,1,1,
1,1,1,1,3,3,1,1,1,1,
0,1,2,1,1,1,1,2,1,0,
0,1,2,2,1,1,2,2,1,0,
1,1,1,1,1,1,1,1,1,1,

];
bitmap(bitmap, block_size, height, row_size);
