ImageFileFormatEnum

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.

Important! Office document formats work with PDF copies of the source documents.
