TXTextControl.DataVisualization.ChartFrame.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 SaveSettings.ImageCompressionQuality property.

public int ExportCompressionQuality { get; set; }

Public Property ExportCompressionQuality() As Integer

Examples

The following snipped shows how to set the TXTextControl.DataVisualization.ChartFrame.ExportCompressionQuality property. Here, it is set to the value: 100 - which equals maximum quality.
