I have old Eastman/eiStream/OpenText document repositories that store TIFF images.

Some of the TIFFs are annotated, with the annotations stored in the TIFF header; these I can manage having found specs for the TIFF header layout and the layouts of the annotations themselves.

Unfortunately there are a small percentage of the TIFFs with "Version2" mark ups that are stored outside the TIFF in a .ano file.

Can anyone point me to a spec that could enable me to decode the contents of the .ano file?

  • Disclaimer: I don't have a spec. But do you have some sample files, maybe someone could reverse-engineer the format? – Harald K Apr 30 '14 at 13:25
  • @haraldK: I've looked, it's complicated, lots of binary data. I can see where the annotations start, and have a heuristic that pulls them out, but having a "best guess" algorithm that runs against a dozen samples in the office is one thing, running it against millions of historic documents on site is another. All round folks here would prefer something written from a canonical spec, me included. – Binary Worrier Apr 30 '14 at 13:36
  • The latest spec I heard of is http://web.archive.org/web/20081020231124/http://support.global360.com/content/I4W/documentation/annospec.htm. These ".ano" files may be a custom in-house extension. – Jk1 Apr 30 '14 at 17:05
  • Thanks @Jk1, that's what I currently have and use for the annotations embedded in the TIFF. those guys are also embedded in the .ano file. – Binary Worrier Apr 30 '14 at 17:08

Looking around on the OpenText website (this page: http://www.opentext.com/What-We-Do/Products/OpenText-Product-Offerings-Catalog/OpenText-Imaging-for-Windows/Image-File-Formats#Annotations) at the bottom it says this about tiff:

TIFF

Are the TIFF image documents created by Imaging for Windows compatible with other image editor/viewer products? Yes. The file format is a standard TIFF 6.0 multi-page, multi-strip or single-strip format. Most TIFF 6.0 capable products are able to view the image pages. In the Imaging application, the TIFF settings reside on the ‘File Options’ dialog box.

If it is desirable for other image file readers to handle the annotations generated by Imaging for Windows, the Annotation Specification is available for download.

However, I could not find the download for the specification anywhere on their site. Could this be the source of those .ano files? I bet they would send you the spec if you emailed them.

  • No, that would be the annotation specification that I already have, it shows how to read the annotations in the tiff header files. It doesn't cover this other. ano file. But thanks anyway. – Binary Worrier May 06 '14 at 06:21
