We are building a software for photo printing.
There are like a thousand libraries out there for basic image manipulations : brightness/contrast, resize, invert, basic filters like emboss, etc. We already have that.
What we need is a library that provides more advanced effects, like Instagram, PicFull, Pixlr, Befunky, Rollip, Fotor, and so many other similar sites.
We need to be able to call it from .Net, on Windows, in a WPF application, but at this point I'm willing to try anything.
On our web application, we already use Aviary, which is great, but has one big problem: it only works online. So, the user has to send his 4-5Mb image to Aviary, which in turn sends it back once modified. While it's ok when the servers are the ones to communicate, it's too much for using on a mostly-offline application.
We are willing to use commercial solutions, so any suggestion is appreciated.
I'm looking literally everywhere for an answer to this question. The best I have found yet is "write your own filters", and this is just not going to cut it.
Thank you!
