Hi Paul,

I apologize for this misleading information. You are correct, there is a problem with the

trial version not assigning the compression property correctly. I have just debugged with

the 1.1 trial units, and the compression remains at tcNone even after,

if Graphic.ImageFormat = ifTrueColor then
TTiffGraphic(Graphic).Compression := tcJPEG

If you need to test this with the evaluation version, send me an email (with your preferred

Delphi version) and I will send you a precompiled EnTifGr.Dcu file.

Best regards,
