Controlling JPEG quality

When you crop JPEG images, the default JPEG compression ratio that reflects on its quality is 80%. You can change this value at will.

1. Edit ~/App_Data/Composite/Configuration/Composite.Media.ImageCrop.xml.
2. In the element configuration/Settings/add[@name='JpegQuality'] set its value attribute to the value between 1 and 100, for example, 60.
3. Restart the server (Tools | Restart Server).

Sample:

<configuration> 
  <AspectRatio> 
    <!-- skipped for readability -->
  </AspectRatio>
  <Settings>
    <add name="JpegQuality" value="60" />
  </Settings>
</configuration>
