scale image to size swift code example
Example 1: increase the size of the image in Swiftui
struct ResizedImage: View {
var body: some View {
Image("myImage")
.resizable()
.scaledToFit()
.frame(width: 200.0,height:200)
}
}
Example 2: swift decrease image size
let actualHeight:CGFloat = image.size.height
let actualWidth:CGFloat = image.size.width
let imgRatio:CGFloat = actualWidth/actualHeight
let maxWidth:CGFloat = 1024.0
let resizedHeight:CGFloat = maxWidth/imgRatio
let compressionQuality:CGFloat = 0.5
let rect:CGRect = CGRect(x: 0, y: 0, width: maxWidth, height: resizedHeight)
UIGraphicsBeginImageContext(rect.size)
image.draw(in: rect)
let img: UIImage = UIGraphicsGetImageFromCurrentImageContext()!
let imageData:Data = UIImageJPEGRepresentation(img, compressionQuality)!
UIGraphicsEndImageContext()
return UIImage(data: imageData)!
