I'm looking for a way to do "automatic cropping." The workflow is this: I have a receipt on my table. I take a picture of it. I'd like the next screen to be the picture, with guides around the page. The guides should be adjustable, but initially the SDK should make the best guess as to the bounds of the receipt within the image. Is this possible? The "Scanner Pro" app does something like this, but they don't offer an SDK.
Sample app is only for SDK demonstration, there is one default image but you can also select your custom images to apply effects but there is no saving. But after applying effects to your uiimage saving is an easy task.

I am interested to know what are the Effects available in the package? Are the effects similar to what's done in the Apple official Photobooth app?
Any update on an AppStore app showing the PhotoFX SDK in a live app?
You can see some of the effects in the screenshots. They are created by chaining Core Image filters. Photo Effects SDK currently does not support Photobooth app like distortion/deformation effects created with OpenGL ES shaders.
We are planning to release a whole photo effects app on PhotoFX SDK that will include all the current effects with probably many of them as in-app purchases. The performance for effects processing is same or faster than many of the current effects apps or plugins. PhotoFX SDK uses Apple's Core Image underneath.
