Image to PDF

The following example illustrates how to load an image file and save it as a single PDF page. Any image file format supported by ImageGear can be used.

PDF support needs to be initialized first for this snippet to work. To get familiar with initializing IGNET, initializing PDF support, loading a PDF, saving a PDF, and terminating PDF support, try any one of the tutorials.
