Design and implementation of multi-platform high quality 2D graphic library

To support the applications be able to draw high quality outputs and cross-platform enabled,a graphics library which has unified interface on multi-platforms,fast rendering ability and better rendering effects is proposed and implemented,so the cross-platform graphics applications are developed much easier.Firstly,the advantages and disadvantages of several existing graphics libraries are stu-died.Then the theory and design to implement a device independent high quality 2D graphic library is explained based on the requirements of digital map drawing system.Finally,in contrast with GDI and GDI+,the improvement in rendering effects and speed of the library are tested.
