Render to PNG or JPEG

When rendering to PNG/JPG, GroupDocs.Viewer renders each page of the source document as a separate PNG or JPG image.

To render files to PNG/JPG, follow these steps:

Create an instance of the Viewer class. Specify the source document path as a constructor parameter.
Instantiate the PngViewOptions or JpgViewOptions object. Specify a path to save the rendered pages.
Call the View method of the Viewer object. Specify the PngViewOptions or JpgViewOptions object as the parameter.
