How to convert NSImage to PNG Data
Issue #885 Create NSBitmapImageRep with preferred size and draw NSImage onto that. Need to construct NSBitmapImageRep specifically instead of using convenient initializers like NSBitmapImageRep(data:), NSBitmapImageRep(cgImage:) to avoid device dependant resolution issue. extension NSImage { func pngData( size: CGSize, imageInterpolation: NSImageInterpolation = .high ) -> Data? { guard let bitmap = NSBitmapImageRep( bitmapDataPlanes: nil, pixelsWide: Int(size.width), pixelsHigh: Int(size.height), bitsPerSample: 8, samplesPerPixel: 4, hasAlpha: true, isPlanar: false, colorSpaceName: .deviceRGB, bitmapFormat: [], bytesPerRow: 0, bitsPerPixel: 0 ) else { return nil } bitmap....
