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.

I am capturing a screenshot with SCScreenshotManager's captureImageWithFilter. The resulting PNG has the same resolution as the PNG taken from Command-Shift-3 (4112x2658) but is 10x larger (14.4MB vs 1.35MB). My SCStreamConfiguration uses the SCDisplay's width and height and sets the color space to kCGColorSpaceSRGB. I currently save to file by initializing a NSBitmapImageRep using initWithCGImage, then representing as PNG with representationUsingType NSBitmapImageFileTypePNG, then writeToFile:atomically. Is there some configuration or compression I can use to bring down the PNG size to be more closely in-line with a Command-Shift-3 screenshot. Thanks!

I am using the following shell script to return an image preview for use in FileMaker: qlmanage -t [sourcePath] -s 512 -o [outputPath] This usually works well, but it hangs if the RGB image (.tif, .psb, or .psd) has too many Alpha Channels ( >20 if on transparent background; >21 if flattened). This issue can be also be seen when looking at the image thumbnail or preview in the Finder. It appears MacOS won't create a thumbnail when the image has over 21 Alpha Channels... it just shows the default tif/psb/psd thumbnail, even if the image is very small. Environment MacOS Sonoma 14.4.1 Adobe Photoshop 2024 (25.6.0) Maximize PSD and PSB File Compatibility is enabled when saved from Photoshop Since I'm only able to upload a screenshot to this post, the original test files can be found in the Adobe Forum with the Title: "MacOS Finder Preview Limited to 20-21 Alpha Channels?"

When i am fetching Images and passing it to await faceapi.fetchImage(label); then i am facing RefrenceError:Can't Find Variable: FileReader Please Help For this.

In my SwiftUI view, I try to load the image from data. var body: some View { Group{ if let data = model.detailImageData, let uiimage = UIImage(data: data) {// no memory issue Image(uiImage: uiimage) .resizable() .scaledToFit() } } } But I want to get the HDR style of my image, so I use if let data = model.detailImageData, let uiimage = UIImageReader.default.image(data:data){ //memory leaks!!! When I change the data, the memory of the previous image is never freeed. finally caused my app to crash. You can see it from the Instrument screenshot.

I use this code to show the Image in HDR in SwiftUI struct HDRImageView: UIViewRepresentable { // Set up a common reader for all UIImage read requests. static let reader: UIImageReader = { var config = UIImageReader.Configuration() config.prefersHighDynamicRange = true return UIImageReader(configuration: config) }() let data:Data? let enableHDR:Bool func makeUIView(context: Context) -> UIImageView { let view = UIImageView() view.preferredImageDynamicRange = enableHDR ? .high : .standard update(view) // Set this view to fit itself to the parent view. view.setContentCompressionResistancePriority(.defaultLow, for: .horizontal) view.setContentCompressionResistancePriority(.defaultLow, for: .vertical) view.setContentHuggingPriority(.required, for: .horizontal) view.setContentHuggingPriority(.required, for: .vertical) return view } func updateUIView(_ view: UIImageView, context: Context) { update(view) } func update(_ view: UIImageView) { autoreleasepool{//not working if let data = data { view.image = nil//set to nil first is not working view.image = HDRImageView.reader.image(data: data) } else { view.image = nil } view.preferredImageDynamicRange = enableHDR ? .high : .standard } } } But when I update the input data, seems that the old image data can not be freeed. After several changes, the app takes too much memory and crash. I found it's the VM:ImageIO_Surface_Data and the VM_Image_IO take up the memory. If I change the HDRImageView into a normal Image(uiimage:UIImage(data:)) It no longer have this issue. Is it a memory leak? and how to solve this. Update: I then tried using Image(_:cgImage), and it appear to be the same result.

I have an image viewing app with support for avif (and avis) images. I'm trying to figure out if the recent bug in CoreMedia (dav1d) affects my app. The apple security update: https://support.apple.com/en-gb/HT214097 The vulnerable code path in dav1d is only reached when c->n_fc > 1 (https://code.videolan.org/videolan/dav1d/-/blob/2b475307dc11be9a1c3cc4358102c76a7f386a51/src/decode.c#L2845), where c is the dav1d context. With some reverse engineering, the way I see CMPhoto calling into VideoToolBox (which internally calls into AV1SW.videodecoder, which is a wrapper around dav1d), the max frame delay is hardcoded to 1 in the dav1d settings which intern means that c->n_fc in dav1d is always 1. The vulnerable code path in dav1d is only reached when c->n_fc > 1 (https://code.videolan.org/videolan/dav1d/-/blob/2b475307dc11be9a1c3cc4358102c76a7f386a51/src/decode.c#L2845). From my understand, this should mean that my app isn't affected. The apple security update however clearly mentions that "Processing an image may lead to arbitrary code execution". Surely I'm missing something?
