Class ChartRasterizer

java.lang.Object
  wt.query.template.ChartRasterizer

public class ChartRasterizer

extends Object

Utility class for converting data in the form of a Swing TableModel into a raster image. Acceptable values for imageFormatName include "JPG" and "PNG".

The constant FORMAT_JPEG can be used to designate encoding using JPG format. By default, for those image format types that enable compression the default compression ratio is set to 75%
