Subject: Saving TIF's with tcNone for compression

I am evaluating envision for a client (I have used earlier versions for doc scanning etc and have been very pleased). They have JPG's from a camera and are wanting to save them as TIF's for an application. They have to be in a very specific format - I thought I had cracked it, but the images I save are not useable.
If I load one of their images and one of mine (theirs work).
Theirs: FCurrentTiff.compression = tcNone
Mine: FCurrentTiff.compression = tcPacked Bits.

I can't seem to change this. I have:
FCurrentJPG:=TJpegGraphic.create;
FCurrentTiff:=TTiffGraphic.create;
FCurrentTiff.compression:=tcNone;
FCurrentTiff.RowsPerStrip:=10;

then later
FTransResize.ApplyOnDest(image.Graphic,FCurrentTiff);
FTransColor.Apply(FCurrentTiff);
//HAve tried the compression line in here as well.
FCurrentTiff.SaveToFile(edTiff.text+'\'+ChangeFileExt(FCurrentDestName,'.TIF'));

image is a brightened version of FCurrentJPG.
Can anyone help?
