This parameter determines how many DPI (dots per inch) should be used when converting a vector page. Typical settings for this parameter are 150, 200, or 300. The higher the DPI, the higher the quality of the image, but also the bigger the size, which means more processing on the server and larger page sizes across the network.

The optimal setting for this varies by format, but 200 is usually good for black & white documents or text, and 300 for color images and more detailed documents. Even higher numbers can be used (400, 600) but it can seriously affect speed of processing and available resources.

The example below shows how to set the DPI parameters in the web.xml file. For a list of of web.xml parameters, please see Servlet Tags for web.xml.
