• Image
  • UIImageJPEGRepresentation
    • data = UIImageJPEGRepresentation(result[:original_image], 0.5) # 50% quality
  • UIImagePNGRepresentation
    • data = UIImagePNGRepresentation(result[:original_image])
    • problem
      • image rotates after restart app (90 degrees)
      • png doesn't store exif (orientation data)
    • fix
      • imageRef = UIImage.imageWithContentsOfFile(App.documents_path + '/key_hook').CGImage
      • rotatedImage = UIImage.imageWithCGImage(imageRef, scale:1.0, orientation:UIImageOrientationRight)
