I decided some time ago to store the descriptions of my pictures (mostly scanned images) inside the pictures themselves. For this I'm using the <caption> field as defined by the International Press Telecommunications Council (IPTC) standard. Several tools like Photoshop and Irfanview allow to store and update this information.

What about GenoPro to fetch this IPTC caption directly from the picture and use it as default value for the "picture description and comments" field?

Regards,
Nand

Thanks for your suggestion. I was not aware of any such standard. My knowledge about pictures/image processing is very limited. I know how to convert a bitmap to a JPEG/GIF/PNG... That's about it :?.

I will take a look at this IPTC standard as well as the DjVu file format.

I found the technical document at http://www.iptc.org/IIM/. This document is very difficult to read with no samples... never mind being almost 6 years old.

The good news is Google made a tool to add "IPTC headers". The tool is available at http://www.picasa.com/

I can provide a VB sample with some test code that retrieves the IPTC caption from a JPEG picture. Just let me know.

Thank you very much. A sample code is always good. I found a technical article with C++ sample code at www.codeproject.com/bitmap/iptc.asp. From my understanding, IPTC is mostly for JPEG images. Does anyone know if there are IPTC headers for other image files? If so, can you please provide a link to the documentation. Thanks.
