# 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.

### Description

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](https://docs.textcontrol.com/tx-text-control-dotnet-winforms/reference/txtextcontrol/savesettings/imagecompressionquality-property/llms-full.txt) property.

### Syntax

```csharp
public int ExportCompressionQuality { get; set; }
```

```vbnet
Public Property ExportCompressionQuality As Integer
```

### Examples

The following example uses `ChartFrame.ExportCompressionQuality` to balance the chart frame's export quality and file size. The change is then applied to the active document or user interface.

```csharp
chartFrame.ExportCompressionQuality = 90;
chartFrame.Refresh();
```

```vbnet
chartFrame.ExportCompressionQuality = 90
chartFrame.Refresh()
```
