I have a csv file with values ranges between 0-1. When converted this csv values to MLMultiArray and then to UIImage it shows grey image. But the image is actually coloured. So is there any step missing or do I have to perform any more action to get this image to be coloured. Sample csv values - [0.556862745 0.62745098 0.811764706]

We are using PNG Transparent logo image for display in Dark and Light theme when sending a mail to the user. So, based on the user's screen settings, i.e. dark or light theme, background of the logo will be Black for Dark theme and White for Light theme.   But this is not working in the case of Yahoo mail app for iPhone dark theme. Yahoo mail app in iPhone for dark theme, by default, renders a white background color on CIBC logo image which is not looking good. Request you to kindly advise on the above. Please find screenshot of the issue attached.

Hello! I'm unable to take pictures from my swiftui app using a simple image picker, the camera sheet comes up but when I take a picture and choose" use this picture", nothing happens, this is the error I keep getting: Attempted to change to mode Portrait with an unsupported device (BackAuto). Auto device for both positions unsupported, returning Auto device for same position anyway (BackAuto). Please does anyone have any advice on how I can fix this

Hi everyone, I'm currently working on an app that allows users in the US and Canada to generate social media captions for their images using AI. The app has a feature where users can save the generated captions, and I'm considering whether or not to store the associated images on Firebase storage. My main goal is to allow users to refer back to their images when they view their saved captions. However, I'm also concerned about potential legal issues that might arise from storing user-generated images, especially since the app is not designed for sharing these images with other users. To give users more control over their data, I'm thinking about adding a toggle in the settings menu that allows them to choose if their images should be stored or not. I believe this could improve transparency and user satisfaction, but I'm unsure if this approach would help me avoid legal issues related to data storage and privacy for US and Canadian users. I would appreciate any insights or suggestions from the community, especially if you have experience with similar features or legal concerns in the context of US and Canadian data protection regulations. Also, I'd be grateful for recommendations on where to seek more information or consult with professionals in this area. Thanks in advance for your help!

Now that ImageCaptureCore framework is supported on iOS 13+, I was trying to write an application for browsing media files on devices connected via USB. The external device is connected to the iPhone via the "Lightning to USB 3 Camera Adapter" - https://www.apple.com/shop/product/MK0W2AM/A/lightning-to-usb-3-camera-adapter. The iOS application I'm writing is based on SimpleCameraBrowser - https://developer.apple.com/library/archive/samplecode/SimpleCameraBrowser/Introduction/Intro.html @interface AppDelegate () <ICDeviceBrowserDelegate, ICDeviceDelegate> @property (nonatomic, strong) ICDeviceBrowser *deviceBrowser; @property (nonatomic, strong) ICCameraDevice *camera; @end @implementation AppDelegate (void)deviceBrowser:(nonnull ICDeviceBrowser *)browser didAddDevice:(nonnull ICDevice *)device moreComing:(BOOL)moreComing {     NSLog( @"deviceBrowser:didAddDevice:moreComing: \n%@\n", device ); //    if (device.type & ICDeviceTypeCamera)     {         device.delegate = self; &#9;&#9;&#9;  self.camera = (ICCameraDevice *)device;         self.camera.delegate = self;         [self.camera requestOpenSession];     } } (void)device:(nonnull ICDevice *)device didOpenSessionWithError:(NSError * _Nullable)error {     NSLog( @"device:didOpenSessionWithError:error: \n%@\n", error );    } (void)deviceDidBecomeReady:(ICDevice*)device {     ICCameraDevice *camera = (ICCameraDevice *)device;     NSLog(@"%@, %@", device, camera.mediaFiles); } (void)deviceDidBecomeReadyWithCompleteContentCatalog:(ICCameraDevice*) device { &#9; NSLog(@"deviceDidBecomeReadyWithCompleteContentCatalog: %@", device.mediaFiles); } (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {     // Override point for customization after application launch.     self.deviceBrowser = [[ICDeviceBrowser alloc] init];     self.deviceBrowser.delegate = self;     [self.deviceBrowser start];          return YES; } What I'm seeing is that although the camera is found and successfully open a session, when receiving the callback deviceDidBecomeReady, the property mediaFiles is an empty array and never receive the call deviceDidBecomeReadyWithCompleteContentCatalog. Is ImageCaptureCore framework supposed to work on iOS? Does it work only on iPads and not on iPhones?

I'm not sure if it's allowed to use. https://docs.midjourney.com/docs/terms-of-service

I'm working on App Shortcuts function with AppIntentsExtension which is recommended in WWDC22. But I'm struggled to download or show image after shortcut is executed. Here are main functions: func perform() async throws -> some IntentResult & ShowsSnippetView & ReturnsValue<URL> { let requestURL = URL(string: "https://cdn.leonardo.ai/users/3e2e4dd4-8b59-4eac-b8c1-e6a89d88da2c/generations/1db4905a-4593-4f49-9d9f-1179221c0ee3/Leonardo_Signature_A_pretty_animation_girl_3.jpg")! let result = FileDownloader.loadFileSync(url: requestURL) // BTW I don't see any log [Full.txt](https://developer.apple.com/forums/content/attachment/e72637a4-7c4e-4545-b66a-ec0a1bc232ca) in Xcode Consle print("Generate image finished") // Not work with or without PictureView // Also tried only return result URL, not work either return .result(value:result, view: PictureView(url: requestURL)) } struct PictureView: View { var url: URL var body: some View { ZStack{ // Cannot show nothing AsyncImage(url: url) // This shows Image(systemName: "photo.on.rectangle.angled") .symbolRenderingMode(.monochrome) .resizable() .scaledToFit() .frame(minWidth: 50, minHeight: 50) } } } Simply saying, I want to just show a image from url or download it so that I can check it out in Photos, using App Intents Extension.

This is on macOS 13.2.1, M1 Max. I'm having an issue appending an attribute using AppleEXR. If I don't append the attribute (i.e. by commenting the code), the file appears to be valid. However when I add the attribute I can no longer load the image, and the opensource OpenEXR lib throws an exception about an attribute name longer than 255 chars. The lines in question are: const int32_t val = 1; const char *name = "acesImageContainerFlag"; const char *type = "int"; auto err = axr_part_append_attribute(part, name, type, sizeof val, reinterpret_cast<const uint8_t *>(&val), 0, nullptr); if (err != axr_error_success) { auto errStr = axr_error_get_name(err); NSLog(@"Failed to set acesImageContainerFlag: %s", errStr); } The err variable is always axr_error_success. Debugging into the opensource OpenEXR library when attempting to load the file, it seems like the attribute name and attribute type aren't being null terminated. I can append the chromaticities attribute successfully using axr_part_set_chromaticities. The structure of my code is as follows: axr_encoder_create axr_encoder_append_part /*axr_part_append_attribute*/ axr_part_set_chromaticities axr_part_append_channels axr_encoder_compress

Hi, I'm trying to convert images picked from the users camera roll into jpegData for me to upload to a server. I'm doing the following to covert to Data: let imageData: Data? = uiImage.jpegData(compressionQuality: 0) This works fine when converting screenshots. But when I attempt to convert an image taken using the device's camera. It gives me the following error: [Metal] 9072 by 12198 iosurface is too large for GPU It still converts it into data, but the data then just contains a blank image. Not the selected image. I'm at a loss with where to go with this one, I've tried converting HEIC preloaded onto the device's bundle and it works fine. But when using ones selected from the camera roll, I get the stated error. Any help would be appreciated. This is the sample code I'm using to test the issue. (I'm aware it's quite pointless in this form) func convertImage(image: Image?) -> Image? { //1 let key = "\(String.random(length: 15))" let uiImage: UIImage = image.asUIImage() let imageData: Data? = uiImage.jpegData(compressionQuality: 0) guard let imageData = imageData else { return nil } let encodedImage = imageData.base64EncodedString() let fileManager = FileManager.default let documentsPath = fileManager.urls(for: .documentDirectory, in: .userDomainMask).first let localImageUrl = (documentsPath?.appendingPathComponent(key)) guard let localImageUrl = localImageUrl else { return nil } try! encodedImage.write(to: localImageUrl, atomically: true, encoding: String.Encoding.utf8) guard let fileContents = try? String(contentsOf: localImageUrl) else { return nil } let dataDecoded : Data = Data(base64Encoded: fileContents, options: .ignoreUnknownCharacters)! let decodedimage = UIImage(data: dataDecoded) return (Image(uiImage: decodedimage ?? UIImage(named: "placeholder")!)) } import SwiftUI struct UploadTesting: View { @ObservedObject var crViewModel = ChatroomsViewModel() @State var showImagePicker = false @State var selectedImage: Image? = nil @State var convertedImage: Image? var body: some View { VStack { Button("Select") { showImagePicker.toggle() } selectedImage?.resizable().scaledToFit().frame(width: 300, height: 300) Button("Convert") { convertedImage = crViewModel.convertImage(image: selectedImage) } convertedImage?.resizable().scaledToFit().frame(width: 200, height: 200).background(Color.red) } .sheet(isPresented: $showImagePicker) { ImagePicker(image: $selectedImage) } } } Video of issue: https://streamable.com/h0uqly

I have a need to tell if 2 images are different by unimportant details. For example, one image is only slightly different than another because: *) It is a little stretched *) or it has 99% portion of another (only missing some pixels on borders) I wonder if there is an efficient algorithm to achieve my goal. Any suggestions are welcome.

I did searches on the Internet but could not find a definitive answer. The best thing I get is CGImageSourceCreateThumbnailAtIndex API function. But I don't know how create CGImageSource out of an NSImage object. Thanks for any suggestions.

I am trying to publish and download images from firebase storage. I publish an Image, and then try to fetch it, which works, but when I try to replace that same image by another one, and then fetch that new image, it still shows me the old image, even though when I look in the database, it shows the new Image and nothing else. There are no errors. This is how I am fetching my image. let storageRef = Storage.storage().reference() let ref = storageRef.child("Profiles/\(UserModel.docId).jpeg")          let placeHolderImage = UIImage(systemName: "person.circle.fill")    profileImage.sd_setImage(with: ref, placeholderImage: placeHolderImage) This is how I am uploading my images let storageRef = Storage.storage().reference() let ref = storageRef.child("Profiles/\(UserModel.docId).jpeg")       let metaData = StorageMetadata() metaData.contentType = "image/jpeg" ref.putData(ImageData, metadata: metaData)

Do we have any api to upload app screenshots and metadata or create experiments with Screenshots and metadata for appstore connect ?

I'm working on a MessageExtension app and trying to send an images with a transparent background through imessage. However when I add the image to the message, the image loses its background transparency and is filled in with a solid white. is there a way to mitigate this? For some more context, the user is picking the image from a CollectionView full of cells that contain a UIImageView. I can see in the CollectionView that the images have transparent backgrounds, and also when I run the program with a breakpoint and view the active variables the image has a transparent background. So I believe it has something to do when adding the image to a message. this is my code for adding the image to a message: guard let conversation = activeConversation else{ print("conversation failed") return } let layout = MSMessageTemplateLayout() layout.image = image //image is a UIImage let message = MSMessage() message.layout = layout conversation.insert(message) {error in if let error = error{ print("error sending message: \(String(describing: error))") } }

I'm writing an iOS Swift app to fetch metadata from DJI drone images. I'm trying to access the Xmp.drone-dji.X metadata. The iOS/Swift CGImageSource and CGImageMetadata libraries/classes get almost all of the metadata out of the image but not the Xmp.drone-dji. When I get a list of tags, those tag/values are not listed. I know the tags/data are in the images because I've examined the images using exif, exiv2, etc. Any suggestions? Here is the code I'm using so far: result.itemProvider.loadDataRepresentation(forTypeIdentifier: UTType.image.identifier) { data, err in if let data = data { let src = CGImageSourceCreateWithData(data as CFData,nil)! let md = CGImageSourceCopyPropertiesAtIndex(src,0,nil) as! NSDictionary let md2 = CGImageSourceCopyMetadataAtIndex(src,0,nil) }

CGFloat width = any value; 　CGFloat height = any value; CGDataProviderRef dataProviderRef = dataProviderRef = CGDataProviderCreateWithData(NULL, data, width * height * 2, nil); CGBitmapInfo bitmapInfo = kCGBitmapByteOrderMask | kCGImageAlphaNoneSkipLast; CGImageRef imageResult = CGImageCreate(width, height, 8, 16, width * 2, CGColorSpaceCreateDeviceGray(), bitmapInfo, dataProviderRef, NULL, 0, kCGRenderingIntentDefault); imageResult is nil. Please tell me an alternative method.

Hi ! I'm testing my HEIF image files on Ventura 13.2 and I found something about different color-tone on Finder's Gallery. Shortly I explain it, Gallery in Finder app shows a HEIF image shows more brighter than Preview app. It did not happen on Ventura 13.1, just happen in 13.2. In order to explain more detail, I attached PPT file and image files. PPT: https://docs.google.com/presentation/d/1743G7KcSGChSFVvmCF0JR-EsBeXkJtLAGpmu6lkgMHU/edit?usp=share_link Image: https://drive.google.com/file/d/1ImfCEWuOhGOLpwsgc5KwRVFTCtVAiZtz/view?usp=share_link So, hopefully, I'm expecting you guys to check this problem and answer this post! Eventually, I hope you fix up this issue that I addressed in this post. Thanks. Seunghoon Baek.
