Subject: Re: Save File Stream As .tif Image
Hi Chris
No problem. Attached is my source. It was a proof of concept so there will be things in there that don't (yet) have any purpose. The code:
* calls web service method 1 for a "job"
* receives one or more file stream ids for that job
* calls web service method 2 for each file stream id
* receives one or more file streams
Thanks to Scott for these service programs!
