'ppm2html' converts an RGB PPM image to an HTML page. The page will display an approximated version of the image only using ASCII characters and color definitions. The tool makes full use of 24 bit color in HTML. If a 'source string' is being defined this string will repeatedly be used as the character source for rendering the ASCII output. If omitted, random characters between 'a' and 'z' will be used. The 'red', 'green', and 'blue' values define the background color of the HTML page. If no command line arguments are given, the page is rendered black. User will get the best results by converting segmented objects (the background of the image is replaced by a single color) and keeping the level of detail low. A small blur on the image results in a nicer visual appearance, especially when displaying text. Note that output varies among different browsers; in particular, horizontal scaling might differ a lot. Using unique renderings for each browser yields the best results.
