Subject: Re: TIFF Image is displayed upside down
In reply to: Dmitriy Mikhelzon 's message, "TIFF Image is displayed upside down" on 13:01:16 04/30/04 Fri


Hi Dmitriy,

Can you email me the file, support@intervalsoftware.com. I don't know what is going on. I assume the tiff file returned AppServer.GetImage is not created by Envision?

Best regards,

Michel
