I am trying to create rails application like slideshare, I had properly
upload my ppt file in to database when I want to perform/display that
particular presentation file.
How can i achieve that without using thirdparties application like
upload ppt file into scribd etc..
please anybody suggest me or give some usefull gems for that...!
ruby_powerpoint is probably a decent place to start:
Note that it only works with new-style pptx files.
For the old format, GOOD LUCK. They are poorly-documented and tricky to work with. Tools like Docsplit (Doc⚡split) might do what you want for these, but they depend on LibreOffice - and correspondingly, can only read PPT files that work in LibreOffice.
One gotcha: none of these will replicate any of the more complex behaviors (animations, transitions). ruby_powerpoint doesn’t even give text style info back, just text and images.
