Supporting PDF files
Opened this issue · 4 comments
Basically there is no Go library to render an PDF into a bitmap. Right now the best solution is Datalogics web-based API: https://api.datalogics-cloud.com/docs#renderpages
However, the developer of gofpdf is considering making a Go wrapper around Google's PDFium (used by Chrome to render PDFs in the browser, for instance). That is an open source implementation of Foxit's FPDF SDK in C++; which confusingly isn't the same as the open source FPDF library to generate PDF files; it cannot render or display them. He will alert us if he starts down that path. If we decide to do this on our own, I suggest open sourcing the blimp rendering bit and alerting him in kind. He may include the functionality as part of gofdpdf.
Why does vip need to support this?
VIP doesn't, per se. But a theoretical "Vokal Media Proxy" might need it. I just wanted a place to pin this for future use.
@foresmac were the memory leaks with Ghostscript ever resolvable? I do think that other than that, it was a good way of dealing with PDFs.
Well, it's never been a problem in production, but I don't know if I solved it by moving to a machine with a bunch more RAM or if no one is uploading PDFs.
