Control External Resources using WorkbookSetting.StreamProvider

Possible Usage Scenarios

Sometimes, your Excel file contains external resources e.g. linked images, etc. Aspose.Cells allows you to control these external resources using Workbook.Settings.StreamProvider that takes the implementation of the IStreamProvider interface. Whenever you will try to render your worksheet containing external resources e.g. linked images, the methods of the IStreamProvider interface will be invoked which will enable you to take appropriate actions for your external resources.
