Okay, This might be a tad odd thing to ask about.
I'm getting into map making for various games. The standard for the elevation maps or heightmaps for the land is universally 16bit greyscale PNG. From my searching far and wide on the Internet, this seems to be the bane of map makers. Unless that is, you can afford Photoshop. There are some other programs, even open source, but they may not fully support the PNG standard and are very basic in features.
In my searching, I came across a list on the LibPNG website of known programs that use LibPNG in some way. Including a handful of Amiga programs. Only most are not available any more.
So, what I want to know is if there are any current image/photo editors for the Amiga, Amiga OS or AROS for me, that have this feature?
