ImageFileFormatEnum enumeration constants are used to specify the format of the image file that can be read or written by means of ABBYY FineReader Engine*. ABBYY FineReader Engine can open image files in all formats described by these enumeration constants, but not all formats are supported for writing.
In Windows and Linux, Office document formats work with PDF copies of the source documents.
The list below may include formats that are not applicable to Linux or Mac. See the table following the list.

* In Linux and Windows, several file formats (used in PDF files, Office documents, and images without specified color type) are unavailable for writing. To save the documents, use the export methods (for example, the Export method of the FRDocument object or the SaveToFile method of the PDFAttachment object for attachments) instead.
