Is there a component in Delphi for viewing PDF files in your application? <br />
I would like to use a free component, that can work without the need to install certain programs on every pc that would use our program ( like Adobe Reader).

A Portable Document Format (PDF) is a file format consisting of an electronic image resembling a printed document and can be viewed, printed, and electronically transmitted. PDF files can store various types of data, including formatted text, vector graphics, and raster images. The page layout defines the location, size, and shape of each page and each item on the page. The information looks the same no matter what device or program is used to open it.
