I am trying to crop image in swift. I'm trying to implement something like, user will capture a photo. Once photo is captured user will be allowed to set the crop area. I'm able to get the image from that crop area, but I want that the crop image should be resized to particular width and height. That is, if particular height or width is smaller then it should be resized.
This image should be of frame of it's maximum width and height. Currently it is just adding transparency to the other area.
I had also added my code for cropping
let tempLayer = CAShapeLayer()
tempLayer.frame = self.view.frame
let path = UIBezierPath()
var endPoint: CGPoint!
for (var i = 0; i<4; i++){
let tag = 101+i
let pointView = viewCrop.viewWithTag(tag)
switch (pointView!.tag){
case 101:
endPoint = CGPointMake(pointView!.center.x-20, pointView!.center.y-20)
path.moveToPoint(endPoint)
default:
path.addLineToPoint(CGPointMake(pointView!.center.x-20, pointView!.center.y-20))
}
}
path.addLineToPoint(endPoint)
path.closePath()
tempLayer.path = path.CGPath
tempLayer.fillColor = UIColor.whiteColor().CGColor
tempLayer.backgroundColor = UIColor.clearColor().CGColor
imgReceiptView.layer.mask = tempLayer
UIGraphicsBeginImageContextWithOptions(viewCrop.bounds.size, imgReceiptView.opaque, 0.0);
imgReceiptView.layer.renderInContext(UIGraphicsGetCurrentContext())
let cropImg = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext();
UIImageWriteToSavedPhotosAlbum(cropImg, nil, nil, nil)
imgReceiptView.hidden = true
let tempImageView = UIImageView(frame: CGRectMake(20,self.view.center.y-80, self.view.frame.width-40,160))
tempImageView.backgroundColor = UIColor.grayColor()
tempImageView.image = cropImg
tempImageView.tag = 1001
tempImageView.layer.masksToBounds = true
self.view.addSubview(tempImageView)Any help will be appreciable
Thanks in advance
