A system for providing a topology map generation service from a service information portal is improved by utilizing an object-oriented class, a mapview module, configured for generating topology maps. The mapview module may be implemented in an object-oriented language such as Smalltalk, C++, JAVA or the like. The mapview module may be configured to provide member functions that include at least associating an output file stream; adding icon symbols and connections symbols between the icon symbols; generating a background graphic (e.g., a building, a geographic map, etc.,); and generating a topology map (or image) by calling a command on an object; and utilizing hypertext transfer protocol ("HTTP") to transfer images across a network. In effect, the mapview module hides all the low-level graphic details for generating a topology view / map / image from a user. Thus, the generation of the topology maps may become easier. Additionally, since the mapview module is an object-oriented class, the mapview module may be used on a variety of computing platforms and support multiple graphic formats such as graphics interchange format ("GIF"), portable network graphics ("PNG") and the like.

The invention discloses a palette device and a generation method for an image with transparency information. The method comprises the following steps: defining the number of independent entries in an appointed palette as K; quantifying RGB (Red, Green and Blue) three primary colors and transparency value of the image with the transparency information; generating K RGB palette entries with Alpha transparency value; obtaining index values of all pixels of the image; and finally saving the values to form a PNG (Portable Network Graphic) 8 image.
