From the Envision Help file:

procedure TMainForm.ImageScrollBoxBeforeSave(
const Sender: TImageScrollBox;
const Graphic: TDibGraphic);
begin
if Graphic is TTiffGraphic then
begin
if Graphic.ImageFormat = ifTrueColor then
TTiffGraphic(Graphic).Compression := tcJPEG
else if Graphic.ImageFormat = ifBlackWhite then
TTiffGraphic(Graphic).Compression := tcGroup4

else
TTiffGraphic(Graphic).Compression := tcPackbits;
end;
end;

used in the "OnBeforeSave" event of the imagescrollbox.

Hope this helps,
Dave
