Graphics Tags

Roxen WebServer features a very advanced graphics engine. Together with output from a database or/and data from the live server the graphics engine can present information that makes a site feel alive. The graphics engine can be set up to automatically generate very nice-looking headers, diagrams, buttons, thumbnails and many other Web graphics :

Images

Through <cimg> images can be transformed and converted to any of the almost 20 image-formats available.

Business Graphics

Generate online reports dynamically with <diagram>, represented as line, bar, pie charts and many other diagrams.

Graphical Headers

Roxen WebServer supports many font-formats and makes it easy to import them. By combining fonts with images and graphical effects very eyecatching headers can be made. For instance, it is possible to set the ordinary HTML-tag <h1> to output a graphical header instead of ordinary boring headers. Graphical headers can be made with <gtext> and <gh>.

Good looking graphics are an important part of the layout of web pages. Creating graphics can also be very demanding of the site's hardware, especially if it involves transforming, converting and rendering of a lot of images or graphics. It is also important to not overdo the website's layout else people with slow connections will not be able to enjoy it since it will take forever to download it.

File Formats

Some of the tags take images as attributes. For example, to use as a background. The images can be of most formats including GIF, JPEG, PSD and PNG.
