Hi, I am making maps and want to have the land transparent to then overlay over Google maps. The way around it I think is to creat the figure with land in black (as nothing else in the image is black) and the have that color made trasnaprent. I have not been able to do this so far... Here's the code, I appreciate anyone pointing me in the right direction. thanks

It's better to paste code than an image of code. Otherwise, if someone wants to try it out, they need to retype everything.

print() to the png file. Then read in the file and write out a new copy of it that has the appropriate color set as transparent. See
