Converts images into LEGO mosaic.
The conversion is made using LEGO 1x1 (part ID: 3005) as pixel. Each pixel RBG is mapped to the limited LEGO Digital Designer (LDD) palette: if we consider each color as a vector,
as the
-th color from the palette,
as the original pixel color, then the new color
is calculated as
for each pixel in the image.
The script returns a .lxfml file (older than the current .lxf) to be opened in LDD.
