TX Text Control .NET for Windows Forms Reference GuideTXTextControl.DataVisualization Namespace ChartFrame Class ExportCompressionQuality Property
Sets a value between 1 and 100, which is the quality of a lossy data compression used, if the chart's image is exported. It is only used, if the image data is compressed with a lossy compression algorithm. A value of 100 indicates the maximum quality, a value of 1 indicates the minimum quality. If this property is set to zero, which is the default value, Text Control uses the quality value set with the Save
