With regard this view PDF topic that's been bounded about of late - I'd last year built a flex app that would parse/decode PDF's and convert the various objects into their various objects - with some limitations I should add.
PDFx were preferable inputs but the results were pretty good - decoding fonts (only the characters within the PDF), text (all ok), images (gifs/jpgs ok but png's were limited to non-alpha channelled). All the binaries could be written to output files (such as the images - regardless of input-format, fonts - although you'd need licensing agreements for the latter - needless to say). Vector graphics were also resolved but I'd had a good few problems resolving RGB>CMYK>RGB colour corrections (somewhat resolved but using native .net components - bit of a bugger as I prefer PHP/MySQL - and generally open-source code bases - you'll all be glad to hear). If anyone would like to positively contribute to the effort (I'd had to give up due to 'proper' responsibilities - but I'm keen to get this behemoth working full-time!) I'd be happy to open up the source - it ain't pretty but it works to a degree… The majority of the work is down to decoding/decrypting various types of Adobe's PDF methods - and it is a beast to overcome (countless hours on PDF discussion sites and binary/bytearray info site (Thibault Imbert of AlivePDF deserves a shout here for fantastic inspiration a good few years ago)) << am I allowed to double-brace comments on a coding forum? I'd have to ask for open-source updates (I don't want anybody to take this and run with it) and as I've not openly sourced anything before - can anyone on the Apache team let me know a good route to go down so as to ensure that my previous work would be collaborated on as opposed to… reaped? I'll look forward to any feedback?
