PDF has become one of the standards for document exchange, and Mac OS X allows the easy creation and viewing of documents in this format. However, creating PDF files programmatically has generally been a difficult feat; the PDF specification, while being published and accessible to anyone, is as complicated as it is powerful.
My goal in making a PDF Class for REALbasic was to make it easy to use for someone who doesn't know the inner workings of the PDF format. I have accomplished this by making the methods mirror those of the REALbasic graphics class. If you can use a REALbasic graphics object to draw graphics and text, you can use REALbasic PDF to create PDF files!
