UIImageView-BetterFace

A UIImageView extension to let the picture-cutting with faces showing better

Last update in v0.2_stable : add a UIImage+BetterFace category, so clipping images becomes possible(clap!)

Looking for an Android version? Check this! [https://github.com/beartung/tclip-android]

##Why?

• Have problems showing the resized image previews?
• People in the preview only have chins but not faces?
• A group photo doesn't look well?

Try UIImageView-BetterFace!

Like this:

##How?

1. Drag UIImageView+BetterFace.h and UIImageView+BetterFace.m to your project
2. Add CoreImage.framework to your project
3. Import the .h file
4. Add this:[anImageView setNeedsBetterFace:YES];
5. If you want all setImage: methods do the magic: Add hack_uiimageview_bf(); to your main function; Otherwise call setBetterFaceImage: for every image you want to make the face detection.
6. Done
7. Still have problems? clone the project and see the demo.

##Too slow?

try set the fast property to YES to get the faster speed(lower accuracy)

##Known issues

• it will be slow to render large-size images, and showing the strange animation
• it may take a lot of memory while reusing the UIImageView

##Who use BetterFace?

• App of http://getprix.com

If you're building your applications using UIImageView-BetterFace, please let me know! (add your application name & App Store link here and pullreuqest this README~

##Debugging Add BF_DEBUG to your pre compile macros or #define BF_DEBUG to your prefix.pch file in order to see turn ON debugging logs on the console.

uiimageview-betterface's Issues

Cycle call？。。。

- (void)setBetterFaceImage:(UIImage *)image{ [self setBetterFaceImage:image]; // Cycle Call? }

if I don't want to hack setImage, this is a Cycle Call.

Deal to slow

Should the hack part been moved to the UIImageView+BetterFace.m ?

Like this in UIImageView+BetterFace.m:

+ (void)load
{
hack_uiimageview_bf();
}

I use this code and success to parse the image in the demo.
I think it would be more intuitive and save the work to deal with "main.m".
Or is there a specific reason not to?

Bug? ImageView doesn't change its image if new image is from Camera.

Full code:

Repro steps:

1. App should let user to choose between photo library and camera as a source of the new image.
2. Select a photo with two faces that works 100% with BetterFace library from the Photo Library.
3. After seeing that BF works fine with the photo from the Photo Library, now select a new photo using the Camera as a source.
4. ImageView still has the old photo from the Photo Library.

Any ideas? I've been debugging this for an hour already.

extension VerificationViewController: UIPickerViewDelegate, UIImagePickerControllerDelegate, UINavigationControllerDelegate {
    
    func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
        picker.dismiss(animated: true, completion: {
            if let newImage = info[UIImagePickerControllerOriginalImage] as? UIImage {
                
                let normalizedImage = newImage.normalizeImage()

                self.imageView_ProfilePicture.needsBetterFace = true
                self.imageView_ProfilePicture.fast = true
                self.imageView_ProfilePicture.setBetterFaceImage(normalizedImage)
                self.imageView_ProfilePicture.makeRoundCorners()
                
                self.imageData = UIImageJPEGRepresentation(normalizedImage, 0.75)
                
                UIView.animate(withDuration: 0.3) {
                    self.label_WarningUploadPhoto.isHidden = self.imageData != nil
                }
            }
        })
    }
}

UIImage+BetterFace，betterFaceImageForSize: accuracy: how to use size param

At UIImage+BetterFace.h，

- (UIImage *)betterFaceImageForSize:(CGSize)size accuracy:(BFAccuracy)accurary;

how to use size parameter？
use image size? or UIImageView size？

Memory so high

First of all, The open source is so cool. Thanks.

In TableView. When I download image from server Use SDWebImage.
The memory is so high. and how can I reduce the memory ?
Can you give me some opinions?

UIImage category not working properly

用 UIImage+BetterFace 切这张图片没有切对。

@candyan 应该是 PR #4 的问题噢。

CocoaPods support😀?
