CIFF Extract File Format
CIFF extract files generated by the CIFF extract task contain logical records preceded by a four byte field containing the logical record length, including its four bytes. After being uploaded to a host system, the files can be converted by the batch job IZGZGCIF, which reconstructs split records into variable record length data sets that can be subsequently processed by host applications. The files are compatible with the Gateway Server incoming file validation process.
Image data records contain the images retrieved with no wrapping conversion or additional wrapping. It is assumed the CIFF extract's input images are already in an image wrapper, such as TIFF.
Each extract file corresponds to a single entry and contains a single header record and trailer record, which enclose the image data records for the entry. Each image data record contains the image data for an item. The file could have none or many image data records, depending on the number of items imaged for the entry and selected extract criteria.
- Segment 1 contains the front black and white image
- Segment 2 contains the front grayscale image
- Segment 3 contains the back black and white image
- Segment 4 contains the back grayscale image
By default, segment 0 is not generated. If the codeline extraction configuration option is active, a basic segment 0 is extracted, containing the codeline fields in a reconstructed process buffer area and other related information. Optionally through the user exit, user reserved segments 13, 14, and 15 can be included in the image data record. The rest of the segments (5 through 12) are never generated.
