How to get UIImage from PDFDraw on Xamarin?

[Ryan]

Question:

I am on Xamarin, and need to get a UIImage object from PDFDraw, how do I that?

Answer:

private UIImage ImageFromRawBGRAData(NSData data, int width, int height, bool isRetina)
{
    using (CGDataProvider provider = new CGDataProvider(data))
    {
        int bitsPerComponent = 8;
        int bitsPerPixel = 4 * bitsPerComponent;
        int bytesPerRow = 4 * width;
        using (var colorSpace = CGColorSpace.CreateDeviceRGB())
        {
            const CGBitmapFlags bitmapInfo = CGBitmapFlags.PremultipliedFirst | CGBitmapFlags.ByteOrder32Little;
            const CGColorRenderingIntent renderingIntent = CGColorRenderingIntent.Default;
            using (var image = new CGImage(width, height, bitsPerComponent, bitsPerPixel, bytesPerRow,
                colorSpace, bitmapInfo, provider, null, false, renderingIntent))
            {
                nfloat screenScale = 1;
                if (isRetina && UIScreen.MainScreen.Scale > 1)
                {
                    screenScale = UIScreen.MainScreen.Scale;
                }

                var myImage = new UIImage(image, screenScale, UIImageOrientation.Up);
                return myImage;
            }
        }
    }
}
