Abstract: An automated document delivery service acquires content from content providers publishing on different schedules and using different URLs to define the path to their web sites. A rule based process of URL generation enables the use of a limited number of resource locator templates and a table of rules to access the web sites and download content of a large number of content providers.

Abstract: Information is provided about operation of a software library accessed by an application program. Information about calls made by the application program into the software library is collected, for example, by capturing a trace of the calls. For a user selected portion of the calls a plurality of event streams are displayed. Within the event streams, events are colored so that a color of each event displayed in each event stream encodes information about a call associated with the event. A first call is represented as a separate event in each event stream in the plurality of event streams and coloring within each event stream encodes different information about the first call.

Abstract: Encoded information is provided about how an image is rendered. When the image is initially rendered, preselected colors are used. The image is re-rendered so that colors used to re-render the image encode information about how the image was originally rendered. For example, the colors for the re-rendered image indicate for each part of the image, the number of vertices included in that part of the image. Alternatively, the colors for the re-rendered image indicate for each part of the image, which type of primitive within a graphics library is used to re-render the first part of the image, or the colors for the re-rendered image indicate for each part of the image, scheduling path within the graphics library used to render that part of the image.
