# SignatureImage.ExportCompressionQuality Property

> Sets a value between 1 and 100, which is the quality of a lossy data compression used if this image is saved. 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 or a compression specific default value.

### Description

Sets a value between 1 and 100, which is the quality of a lossy data compression used if this image is saved. 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-server/reference/txtextcontrol/savesettings/imagecompressionquality-property/llms-full.txt) property or a compression specific default value.

### Syntax

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

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

### Examples

The following example adds a visible handwritten-signature image to an approval field by using `SignatureImage.ExportCompressionQuality`.

```csharp
SignatureImage signatureImage = new(@"Images\alex-smith-signature.svg", 0);
SignatureField approval = new(new System.Drawing.Size(3000, 1000), "ApproverSignature", 10) { Image = signatureImage };
textControl.SignatureFields.Add(approval, FrameInsertionMode.AsCharacter);

signatureImage.ExportCompressionQuality = 90;
Console.WriteLine($"Export Compression Quality used by Signature Image: {signatureImage.ExportCompressionQuality}");
```

```vbnet
Dim signatureImage As New SignatureImage("Images\alex-smith-signature.svg", 0)
Dim approval As New SignatureField(New System.Drawing.Size(3000, 1000), "ApproverSignature", 10) With { .Image = signatureImage }
textControl.SignatureFields.Add(approval, FrameInsertionMode.AsCharacter)

signatureImage.ExportCompressionQuality = 90
Console.WriteLine($"Export Compression Quality used by Signature Image: {signatureImage.ExportCompressionQuality}")
```
