For my semester assignment, I want to make a simple C#/.NET windows desktop application that will call the Instagram API and use its Photo Effects/Filters.
But my professor has said that the app must be a standalone windows desktop app which means it should not have any internet or database connectivity.
For example: If a user selects an image/photo from his computer using the desktop application (that I want to develop), I want the application to show a bunch of Instagram filters that can applied to that image (without internet or any database connection).
My basic question: Is it possible for me to develop such an app that uses the Instagram API but does not need any internet or database connectivity? If it is possible, can you guys guide me? I have visited instagram.com/developer/authentication/ link but I am not sure what to do. And if it is not possible, is there any other way to make an app that applies some effects/filters to an image? Please help me out.
EDIT: I am still a little confused though. When we use Instagram on phone, we use internet only when we want to upload a photo. Filters are offline features. So is there any way I can get these features from the API? As my teacher said I 'can use API but not internet' I assumed APIs can work without the need of an internet connection.
To implement offline image processing, you would either need an assembly of the filters or the actual code. I don't think that Instagram provides such tools. But there are plenty of third party libraries out there for image processing, if that's what you are looking for. For instance the AForge image processing.
