Native PNG Extension

The most time consuming part of the chart creation is the process of encoding memory image to some external graphics format like PNG. Particularly big images take a quite long time to compress and encode. Davisor Chart's default and custom made PNG encoder is written with pure Java. This implementation is highly optimized and performs very well when compared to other Java PNG encoders. However in some heavy load applications a native PNG encoder can bring significant performance boost.

Davisor has a native PNG encoder that can be plugged to Davisor Chart core product. The drawback is that the installation is somewhat more complicated because the native code is always platform and operation system dependant.
