  1. POiOS: Getting started with the Camera and Custom Image Editing
    text
    copied!<p>My app will let users cut out things from photos. They'll be able to either select a photo already in their iPhone's photo library, or take a new one with the camera. From what I understand, UIImagePicker is the simplest way to accomplish picking a photo from the library or taking a new one. However, I also understand that it only provides basic image editing (zoom, crop). I want my image editing to allow for the creation of Bezier curves that, once all joined together, will cut out the enclosed area, saving it without the surrounding background.</p> <p>The official apple documentation on UIImagePicker suggested that the AV Framework is required for providing custom image editing as opposed to the basic zoom and crop. So my first questions are:</p> <ol> <li><p>Is the AV Framework indeed what I want to use?</p></li> <li><p>Will it get used in conjunction with UIImagePicker (i.e., UIImagePicker is used to select the photo or take a new one, and then my AV Framework code takes over for the image editing)?</p></li> <li><p>Can anyone offer good resources on getting started on learning the code for this process?</p></li> </ol> <p>My final question is about the actual Bezier curve generation/manipulation. It appears that the Core Graphics Framework has support for this, but there is also the UIBezierPath object, which is apparently some kind of wrapper for the Core Graphics tools I would otherwise use.</p> <p>So my final question: will I want to use the UIBezierPath object, or does what I previously described require more fine-grained control that UIBezierPath can't provide, thereby forcing me to use the Core Graphics framework directly?</p> <p>Thanks!</p>
