This seems to be a problem with using JPEG. My questions are:
- How to remove the grey areas around the text? What filter/process in GIMP/ImageMagick or other free image editing/scripting mediums would you recommend?
- What would be a programmatic approach to cleaning an image like this? E.g. converting it to a bitmap and applying some filter or process using scripting, etc.
- What is the preferred web friendly file format to not end up with such dirty looking images?
