Save Images with Different Processing in IronOCR

How can I save an image with different image processing/image filters applied?

Apply the following simple code example:

OcrInput Input = new OcrInput(browsFile_txt.Text);
    // Image filter being tested
    Input.ToGrayScale();
    foreach (var p in Input.Pages)
    {
    p.SaveAsImage($"{outputPath}\\{DateTime.Now.ToString("yyyyMMddhhmmss")}.png");
    }

OcrInput Input = new OcrInput(browsFile_txt.Text);
    // Image filter being tested
    Input.ToGrayScale();
    foreach (var p in Input.Pages)
    {
    p.SaveAsImage($"{outputPath}\\{DateTime.Now.ToString("yyyyMMddhhmmss")}.png");
    }

Dim Input As New OcrInput(browsFile_txt.Text)
	' Image filter being tested
	Input.ToGrayScale()
	For Each p In Input.Pages
	p.SaveAsImage($"{outputPath}\{DateTime.Now.ToString("yyyyMMddhhmmss")}.png")
	Next p
