# MLFeatureValue Implementations ## Topics ### Initializers [`convenience init(CGImage: CGImage, constraint: MLImageConstraint, options: [MLFeatureValue.ImageOption : Any]?) throws`](/documentation/CoreML/MLFeatureValue/init(CGImage:constraint:options:)-1j00l) Creates a feature value that contains an image defined by a core graphics image and a constraint. [`convenience init(CGImage: CGImage, orientation: CGImagePropertyOrientation, constraint: MLImageConstraint, options: [MLFeatureValue.ImageOption : Any]?) throws`](/documentation/CoreML/MLFeatureValue/init(CGImage:orientation:constraint:options:)-87vk0) Creates a feature value that contains an image defined by a core graphics image, an orientation, and a constraint. [`convenience init(CGImage: CGImage, orientation: CGImagePropertyOrientation, pixelsWide: Int, pixelsHigh: Int, pixelFormatType: OSType, options: [MLFeatureValue.ImageOption : Any]?) throws`](/documentation/CoreML/MLFeatureValue/init(CGImage:orientation:pixelsWide:pixelsHigh:pixelFormatType:options:)-4nme0) Creates a feature value that contains an image defined by a core graphics image and its orientation, size, and pixel format. [`convenience init(CGImage: CGImage, pixelsWide: Int, pixelsHigh: Int, pixelFormatType: OSType, options: [MLFeatureValue.ImageOption : Any]?) throws`](/documentation/CoreML/MLFeatureValue/init(CGImage:pixelsWide:pixelsHigh:pixelFormatType:options:)-2zg43) Creates a feature value that contains an image defined by a core graphics image and its size and pixel format. [`convenience init(imageAtURL: URL, constraint: MLImageConstraint, options: [MLFeatureValue.ImageOption : Any]?) throws`](/documentation/CoreML/MLFeatureValue/init(imageAtURL:constraint:options:)) Creates a feature value that contains an image defined by an image URL and a constraint. [`convenience init(imageAtURL: URL, orientation: CGImagePropertyOrientation, constraint: MLImageConstraint, options: [MLFeatureValue.ImageOption : Any]?) throws`](/documentation/CoreML/MLFeatureValue/init(imageAtURL:orientation:constraint:options:)) Creates a feature value that contains an image defined by an image URL, an orientation, and a constraint. [`convenience init(imageAtURL: URL, orientation: CGImagePropertyOrientation, pixelsWide: Int, pixelsHigh: Int, pixelFormatType: OSType, options: [MLFeatureValue.ImageOption : Any]?) throws`](/documentation/CoreML/MLFeatureValue/init(imageAtURL:orientation:pixelsWide:pixelsHigh:pixelFormatType:options:)) Creates a feature value that contains an image defined by an image URL and the image’s orientation, size, and pixel format. [`convenience init(imageAtURL: URL, pixelsWide: Int, pixelsHigh: Int, pixelFormatType: OSType, options: [MLFeatureValue.ImageOption : Any]?) throws`](/documentation/CoreML/MLFeatureValue/init(imageAtURL:pixelsWide:pixelsHigh:pixelFormatType:options:)) Creates a feature value that contains an image defined by an image URL and the image’s size and pixel format. --- Copyright © 2026 Apple Inc.
