====================JBCroppableImageView is a subclass of UIImageView built with UIKit and
CoreGraphics that adds n points on an image allowing to modify them by drag &
drop to trim the extra space of an image.Features
-------------------------------------------------* Add an NSArray of specific CGPoints to a UIImageView. * Add a specific number of points. * Drag&Drop of the points. * Crops the UIImage in a UIImageView. * Respects aspect ratio. * ARC(Automatic Reference Counting) support.
Installation
-------------------------------------------------* Drag the *JBCroppableImageView*/*JBCroppableLayer* files into your project. * Add the CoreGraphics framework to your project.
Usage (see example Xcode project in /TestCroping)
-------------------------------------------------to set up, initialize how you would a reular UIImageView:
-JBCroppableImageView *cropView = [[JBCroppableImageView alloc]
initWithImage:[UIImage imageNamed:”demo”]];it will be initialized with four crop points. To add or subtract the number of
points:
[cropView addPoint];[cropView removePoint];to crop the imageView to the requested shape or to revert back to uncropped
state:
[cropView crop];[cropView reverseCrop];to retrieve the cropped image:
[cropView getCroppedImage];[cropView getCroppedImageWithTransparentBorder:YES];*the image property of JBCroppableImageView remains as the original image
