I'm going to have about one hundred ~6 color PNGs that I can convert to TXT files with ImageMagik, giving me something like this:
# ImageMagick pixel enumeration: 54,30,255,srgba
14,0: (255,255,255,0) #FFFFFF00 srgba(255,255,255,0)
15,0: (255,255,255,0) #FFFFFF00 srgba(255,255,255,0)
16,0: (255,255,255,0) #FFFFFF00 srgba(255,255,255,0)
17,0: (255,0,255,1) #FF00FF magenta
18,0: (255,0,255,1) #FF00FF magenta
19,0: (255,0,255,1) #FF00FF magenta[/code:3ezv28hx]
So I can take these outputs and convert them to a tilemap based on the pixel color.
