    viewer.View(options);
}

Step 4: Render to PNG

Transform the Numbers file into PNG format using the following code:

pageFileFullPath = Path.Combine(outputDirectory, "Numbers_result.png");
using (Viewer viewer = new Viewer(TestFiles.SAMPLE_NUMBERS))

    PngViewOptions options = new PngViewOptions(pageFileFullPath);
    viewer.View(options);
}
