[C#]

using (Aspose.Imaging.FileFormats.Gif.Blocks.GifFrameBlock firstBlock = new Aspose.Imaging.FileFormats.Gif.Blocks.GifFrameBlock(100, 100))
using (Aspose.Imaging.FileFormats.Gif.GifImage gifImage = new Aspose.Imaging.FileFormats.Gif.GifImage(firstBlock))
{
    if (gifImage.ActiveFrame != null)
    {
        System.Console.WriteLine("Active frame size: {0}", gifImage.ActiveFrame.Size);
    }
    else
    {
        System.Console.WriteLine("Active frame is not set");
    }

    System.Console.WriteLine("Clear all the blocks");
    gifImage.ClearBlocks();

    if (gifImage.ActiveFrame != null)
    {
        System.Console.WriteLine("Active frame size: {0}", gifImage.ActiveFrame.Size);
    }
    else
    {
        System.Console.WriteLine("Active frame is not set");
    }
}

// The output looks like this:
// Active frame size: { Width = 100, Height = 100}
// Clear all the blocks
// Active frame is not set
