GhostFriend (formerly GoBatchGS)
GhostFriend - a Friendly Frontend for GhostScript
GhostScript can convert PostScript and PDF to various other formats like JPEG, TIFF, PDF. Wolfgang Glunz' PStoEdit is an add-on to GhostScript that converts PostScript and PDF to vector formats like AutoCAD DXF and to WMF. Offering numerous options, these command line tools are very flexible, but not so easy to use. The popular GSView (or GhostView) GUI didn't offer what I needed: a simple tool to process a bunch of PDF or PostScript files.
So I created this GUI, named GhostFriend (formerly "GoBatchGS"). The most important output formats are implemented, as well as the most important options, like resolution, JPEG quality, dithering and even the option to merge PDF output.
