Specifies the compression level for encoding the chart as a PNG image.
object.SetPNGCompLevel( comp_level )
The PNG compression level parameter is an integer between 0 to 9.
Specify 9 for high compression (small file, slowest), 1 for low compression (larger file, faster),
0 for no compression (largest file, fastest).
The default compression level is 3.
The following JScript code illustrates use of the SetPNGCompLevel method.
chart.SetSeparators(";", true); chart.SetDataFromQuery(); chart.LoadStyle("C:\\myStyle.scs"); // Choose the PNG encoding quality chart.SetPNGCompLevel(9); // Outputs the chart as a PNG image chart.SetOutputFormat("PNG"); chart.ExportAsResponse();
