Hi everyone, I've been working with the autoAdjustmentFilters provided by Core Image, which includes filters like CIHighlightShadowAdjust, CIVibrance, and CIToneCurve. However, I’ve noticed that the results differ significantly from the "Auto" enhancement feature in the Photos app. In the Photos app, the Auto function seems to adjust multiple parameters such as contrast, exposure, white balance, highlights, and shadows in a more advanced manner. Is there an API or a framework available that can replicate the more sophisticated "Auto" adjustments as seen in the Photos app? Or would I need to manually combine filters (like CIExposureAdjust, CIWhitePointAdjust, etc.) to approximate this functionality? Any insights or recommendations on how to achieve this would be greatly appreciated. Thank you!

The apps. like viber, whatsapp are not able to recognize/ upload the photos after 18.01 installation.

I am building an app about photos and I want to create a photo sharing feature like Apple's Photos App. Please see Steps to Reproduce and attached project. The current share method has the following issues The file name of the shared photo changes to “FullSizeRender”. The creation and update dates of shared photos will change to the date they were edited or shared. I want to ensure that the following conditions are definitely met Share the latest edited version. The creation date should be when the original photo was first created. How can I improve the code?

I'm adding support for Genmoji to my app but it's unclear to me if this is something that should be called manually in code to insert an adaptive image glyph or if this is something that the system calls when the user inserts a Genmoji / adaptive image glyph object (ie. sticker) into the UITextView.

I'm using UIKit to display a long list of large images inside a SwiftUI ScrollView and LazyHStack using UIViewControllerRepresentable. When an image is loaded, I'm using SDWebImage to load the image from the disk. As the user navigates through the list and continues to load more images, more memory is used and is never cleared, even as the images are unloaded by the LazyHStack. Eventually, the app reaches the memory limit and crashes. This issue persists if I load the image with UIImage(contentsOfFile: ...) instead of SDWebImage. How can I free the memory used by UIImage when the view is removed? ScrollView(.horizontal, showsIndicators: false) { LazyHStack(spacing: 16) { ForEach(allItems) { item in TestImageDisplayRepresentable(item: item) .frame(width: geometry.size.width, height: geometry.size.height) .id(item.id) } } .scrollTargetLayout() } import UIKit import SwiftUI import SDWebImage class TestImageDisplay: UIViewController { var item: TestItem init(item: TestItem) { self.item = item super.init(nibName: nil, bundle: nil) } required init?(coder: NSCoder) { fatalError("init(coder:) has not been implemented") } override func viewDidLoad() { super.viewDidLoad() let imageView = UIImageView(frame: CGRect(x: 0, y: 0, width: 200, height: 200)) imageView.center = view.center view.addSubview(imageView) imageView.sd_setImage(with: item.imageURL, placeholder: nil) } } struct TestImageDisplayRepresentable: UIViewControllerRepresentable { var item: TestItem func makeUIViewController(context: Context) -> TestImageDisplay { return TestImageDisplay(item: item) } func updateUIViewController(_ uiViewController: TestImageDisplay, context: Context) { uiViewController.item = item } }

My App will dynamically load different immersive furniture design scenes. After each scene is loaded, I need to set the HDR image as ImageBasedLight. How can I load EnvironmentResource dynamically? This way I can set the ImageBasedLightComponent dynamically

Hi Team, We have been working on one image processing app developed using react. In this app we are making the XMLHttpRequests to the server and storing the response in the cache which has around 200MB - 250MB of size. We are tracking the memory footprint using the Xcode instrument tool. While downloading and rendering the data in app the Xcode instrument shows the memory footprint around 800MB - 1000MB. We are assuming that garbage collection is not working as expected or some resources are not released after use and because of this we get this high memory footprint for 200MB - 250MB data. If the data is changed then we are removing the existing data from cache and storing the new data. But here, when we delete the data from cache, it does not release the memory immediately and takes some time of 3 seconds or more. In between this, the memory gets allocated to new data too and that increases the overall memory footprint of the app and in some cases the app is crashing. The maximum memory we have seen is average 1.5GB which varies with the device configuration. When we try the same activity on a safari browser where memory gets released immediately. If an app releases the initial acquired memory while loading new data we see very less app crashes. We need help to understand if there is a way to release the memory immediately to avoid the app crash. To reproduce this scenario, we have created a simple app which creates an array with size of 100MB and checks the memory footprint using the Xcode instrument tool. When we create an array of 100MB size, sometimes it shows the memory footprint peak of around 700MB-800MB and when we clear the array by assigning it with an empty array it releases the memory after 2-3 seconds. Created an array and then removed it and after removal of the array, created a new array of the same size immediately and again removed it. Because the memory is not released in time, if you repeat these steps a few times the app memory footprint will increase and that crashes the app.

I have a 3х3 Matrix which I need to apply to UIImage and save it in Documents folder. I successfully converted the 3x3 Matrix (represented as [[Double]]) to CATrasform3D and then I have broken my head with trying to figure out how to apply it to UIImage. The only property where I can I apply it is UIView(or UIImageView in case with working with UIImage) transform property. But it has nothing to do with UIImage itself. I can't save the UIImage from transformed the UIImageView with all the transformations. And all the CoreGraphic methods (like concatenate for CGContext) only work with affine transformations which not suits for me. Please give me a hint what direction I should look. Does Apple has native methods or I have to use 3rd party frameworks for this functionality?

So I have an ios app using wkwebview - ionic framework, my images (not local and hosted) can be seen in ios 17 in my app but not in ios 18. Is there some changes in wkwebview for this particular thing or am I missing something else?

Dear all, I'm building my first MacOs app. I've created my app icon and add it to AppIcon folder, but when I'm building the application the icon shows in the dock of the screen with no rounded borders like all the other apps. I'm attaching here the icon and as you can see it has sharp edges. It is the same way in which it shows on the dock. Why? Has anybody experienced the same? Thanks for the support in advance, A.

It seems that there’s still no way to get all TIFF tags from a TIFF image, is that right? I've got these GeoTIFF images that have a handful of specialized TIFF tags in them. Calling CGImageSourceCopyPropertiesAtIndex(), I can see basic properties common to all TIFF images, like dimensions and color/pixel information, but no others. Short of including libtiff, is there another way to get at the metadata? I've tried all of the options in CGImageSourceCopyAuxiliaryDataInfoAtIndex. I've written a few bugs about this since 2020, all ignored.

Hi, Experts I am using phpickerviewcontroller to open photos in iPhone. It works well for most of photos, such as jpeg, heif. But it failed for photo with raw image on iPhone14 plus. And I found the TypeIdentifier for it is com.adobe.raw-image. I use result.itemProvider.loadFileRepresentation(forTypeIdentifier: "com.adobe.raw-image") to load the raw photo, it always failed, with "Error loading file representation: Cannot load representation of type com.adobe.raw-image". I had try some other param: such as forTypeIdentifier: public.image, public.camera-raw-image, both of them did not work. How can I load this type of raw photo? Below is my code details: // MARK: - PHPickerViewControllerDelegate func picker(_ picker: PHPickerViewController, didFinishPicking results: [PHPickerResult]) { picker.dismiss(animated: true, completion: nil) var resultIndex = 0 DDLogInfo("Pick \(results.count) photos") for result in results { resultIndex += 1 DDLogInfo("Process \(resultIndex) photo") DDLogInfo("Registered type identifiers for itemProvider:") for typeIdentifier in result.itemProvider.registeredTypeIdentifiers { DDLogInfo("TypeIdentifier \(typeIdentifier)") } if(result.itemProvider.hasItemConformingToTypeIdentifier(UTType.image.identifier)) { DDLogInfo("Result \(resultIndex) is image") } if result.itemProvider.canLoadObject(ofClass: UIImage.self) { DDLogInfo("Can load \(resultIndex) image") //more code for photo } else { DDLogInfo("Load special image, such as raw") result.itemProvider.loadFileRepresentation(forTypeIdentifier: "com.adobe.raw-image") { url, error in if let error = error { DDLogInfo("Error loading file representation: \(error.localizedDescription)") return }

Hi, Currently my app is using ImageCaptureCore framework to work with DSLR camera. But when I tested it in iOS 18, it turns out my camera cannot do connection with iPhone by wired connection. It seems there are some developer run into the same problem, there are: https://forums.developer.apple.com/forums/thread/756960 https://stackoverflow.com/questions/78618886/icdevicebrowser-fails-to-find-any-devices-after-ios-18-update And it’s reproduced in some apps that expected to use ImageCaptureCore framework. I’d like to clarify that: Is the issue currently iOS 18 bugs? Is there any plan of Apple to remove wired connection support of ImageCaptureCore framework? Thank you.

I am currently running iOS 18 Beta 3 and am working on enabling users to paste (and copy) custom emojis (AdaptiveImageGlyph, such as Memoji, Stickers, and soon GenMoji) into a text field. I am looking for the UTI for AdaptiveImageGlyph—something similar to "public.adaptive-image-glyph". Does anyone know if such a UTI exists? Here’s my situation: When typing AdaptiveImageGlyph using the System keyboard, everything functions correctly. However, if I copy some text containing AdaptiveImageGlyph from the Notes app and paste it into my playground app, it only pastes the text. The reverse is also true. In fact, if I copy some AdaptiveImageGlyph from the playground app and paste it, it only pasts the text. Interestingly, copying AdaptiveImageGlyph from the Notes app and pasting it into iMessage works flawlessly, and vice versa. I am trying to achieve the same seamless functionality in my app. Given that this feature works in iMessage and Notes, I am inclined to believe the issue might be on my side, though I recognize these are system apps and not third-party. Example Code: import SwiftUI import UIKit struct AdaptiveImageGlyphTextView: UIViewRepresentable { class Coordinator: NSObject, UITextViewDelegate { var parent: AdaptiveImageGlyphTextView init(parent: AdaptiveImageGlyphTextView) { self.parent = parent } func textViewDidChange(_ textView: UITextView) { parent.text = textView.text } func textView(_ textView: UITextView, shouldChangeTextIn range: NSRange, replacementText text: String) -> Bool { // Handle insertion of adaptive image glyphs here if needed return true } } @Binding var text: String func makeCoordinator() -> Coordinator { Coordinator(parent: self) } func makeUIView(context: Context) -> UITextView { let textView = UITextView() textView.delegate = context.coordinator textView.supportsAdaptiveImageGlyph = true textView.isEditable = true textView.isSelectable = true textView.font = UIFont.systemFont(ofSize: 17) // Enable paste with NSAdaptiveImageGlyphs textView.pasteConfiguration = UIPasteConfiguration(acceptableTypeIdentifiers: [ "public.text", "public.image", "public.adaptive-image-glyph" // Replace with the correct UTI if different ]) return textView } func updateUIView(_ uiView: UITextView, context: Context) { if uiView.text != text { uiView.text = text } } } struct ContentView: View { @State private var text: String = "" var body: some View { AdaptiveImageGlyphTextView(text: $text) .frame(height: 200) .padding() } } #Preview { ContentView() }

Hi, I'm looking to update the metadata properties of a DNG image stored on disc, saving to a new file. Using ImageIO's CGImageSource and CGImageDestination classes, I run into a problem where by the destination doesn't support the type of the source. For example: let imageSourceOptions = [kCGImageSourceShouldCache: false] as CFDictionary if let cgImageSource = CGImageSourceCreateWithURL(sourceURL as CFURL, imageSourceOptions), let type = CGImageSourceGetType(cgImageSource) { guard let imageDestination = CGImageDestinationCreateWithURL(destinationURL as CFURL, type, 1, nil) else { fatalError("Unable to create image destination") } // Code to update properties and write out to destination url } } When this code is executed I get the following errors on the command line when trying to create the destination: 2024-06-30 11:52:25.531530+0100 ABC[7564:273101] [ABC] findWriterForTypeAndAlternateType:119: *** ERROR: unsupported output file format 'com.adobe.raw-image' 2024-06-30 11:52:25.531661+0100 ABC[7564:273101] [ABC] CGImageDestinationCreateWithURL:4429: *** ERROR: CGImageDestinationCreateWithURL: failed to create 'CGImageDestinationRef' I don't see a way to create a destination directly from a source? Yes, the code works for say a JPEG file but I want it to work for any image format that CGImageSource can work with?

I want to display my own image in an inline widget. Using the SwiftUI Image syntax doesn't show the image, so following advice from online forums, I used the syntax Image(uiImage: UIImage(named: String)). This successfully displays the image, but if I change the image file name in the app, the image doesn't update properly. I tested displaying the image file name using Text in the inline widget, and it correctly shows the updated file name from my app. So, my AppStorage and AppGroups seem to be working correctly. I'd like to ask if there's a way to update my images properly and if there's an alternative method to display images without converting them to UIImage. Thanks.

In the example https://developer.apple.com/documentation/imageio/writing-spatial-photos, we see that for each image encoded with the photo we include the following information: kCGImagePropertyGroups: [ kCGImagePropertyGroupIndex: 0, kCGImagePropertyGroupType: kCGImagePropertyGroupTypeStereoPair, (isLeft ? kCGImagePropertyGroupImageIsLeftImage : kCGImagePropertyGroupImageIsRightImage): true, kCGImagePropertyGroupImageDisparityAdjustment: encodedDisparityAdjustment ], Which will identify which image is left, and which is right, also information about group type = stereo pair. Now, how do you read those back? I tried to implement a reading simply with CGImageSourceCopyPropertiesAtIndex, and that did not work, getting back "No property groups found." func tryToReadThose() { guard let imageData = try? Data(contentsOf: outputImageURL), let source = CGImageSourceCreateWithData(imageData as NSData, nil) else { print("cannot read") return } for i in 0..<CGImageSourceGetCount(source) { guard let imageProperties = CGImageSourceCopyPropertiesAtIndex(source, i, nil) as? [String: Any] else { print("cannot read options") continue } if let propertyGroups = imageProperties[String(kCGImagePropertyGroups)] as? [Any] { // Process the property groups as needed print(propertyGroups) } else { print("No property groups found.") } //print(imageProperties) } } I assume maybe CGImageSourceCopyPropertiesAtIndex expects something as a 3rd parameter. But in the https://developer.apple.com/documentation/imageio/cgimagesource "Specifying the Read Options" I don't see anything related to that.
