OriginalFormat # get (IOcrPage)
A RasterImageFormat enumeration member indicating the original file format of this page.
The original file format of the page is the format of the original file on disk, memory or URL, used when creating this IOcrPage. If this page was created from a RasterImage object created directly in memory, the format will be RasterImageFormat.Unknown.
The value of the OriginalFormat property can be useful when exporting the page back into a disk file with the format it was originally loaded from.
