This is the number of the filter in the string returned through the ImageCollection.ExportFilters property, beginning with number one. If the ImageCollection.ExportFilters property is used to initialize the FileDialog.Filter property of a Framework dialog, the FileDialog.FilterIndex property can be used as value for this property. A value of zero indicates that the original format of each image is used. The original format can be obtained with the Image.FilterIndex property. For a single image the value of this property can be overwritten with the Image.ExportFilterIndex property. The technical article Loading and Saving Images describes how images can be loaded and saved.
