a Bitmap saved as a PNG is a PNG.
So if you have a wx.Bitmap and do something wacky as
bmp.SaveFile("someScan.png", wx.BITMAP_TYPE_PNG)
you'll end up with a png.
If you want something like optimised size of PNG you could use PIL or maybe pass the resulting images through something like pngcrush.

Hi all,
my little scanner app is almost done. I'll write down some experiences
(more related to twain module than wx / wxPython) soon and make it
available.However, the remaining obstacle is that I don't know how to convert the
image generated by a scan, which is available as DIB file and converted
to a Bitmap for display. I've seen docs and examples on ImageHandler,
specifically PNGHandler, but it seems it can just be used to load / save
PNG files, not convert DIB / BMP to PNG.
