INFO: Zetafax fax image support.

This Zetafax technical note applies to:

  • Zetafax API and server version 5.5 and earlier


From Zetafax 6 the Zetafax server will automatically convert most graphics format files submitted via ZSUBMIT or the Zetafax API (version 6 or later only) into the correct format for sending.

With Zetafax 5.5 and earlier, the server (and so the API) only support TIFF-FAX format files as the graphics file format for sending.  However this is a standard format, and there are a number of 3rd party products that will convert the graphics file format.

More information

The Zetafax client uses a set of graphics filters to convert other types of graphics files into the correct format - you can send graphics files directly using " File/Send" without having to print them.  The set used with Zetafax 6 are produced by Snowbound Software.

We have been pleased and impressed with Snowbound and their products.  These are also available on a single licence basis, and we would recommend contacting them if you wish to add format conversion into your application.
