I am interested in writing some text metadata into the .PNG map tiles generated by Mapnik. Has anyone else done this?
Not me...
I'm having trouble locating a Python module for writing PNG metadata -- PyPNG appears to be able to read the metadata preamble but doesn't appear to be able to write to it.
I am not familiar with the Python bindings. Do they use their own PNG writing code? Because if you'd use the C API, then all you should have to do is add a suitable call to libpng's png_set_text routine in mapnik/png_io.hpp where the PNG is written.
