Subject: Frame support in TScanner

I'm trying to add frame support to TScanner. I've copied some test code that I found in enscan.pas but the image frame doesn't change. I always get the default height as set by the twain interface.

twImageLayout.Frame.Left := SingleToFix32(0);
twImageLayout.Frame.Top := SingleToFix32(0);
twImageLayout.Frame.Right := SingleToFix32(8.5);
twImageLayout.Frame.Bottom := SingleToFix32fPageHeight);
twImageLayout.DocumentNumber := 1;
twImageLayout.PageNumber := 1;
twImageLayout.FrameNumber := 1;

CallTriplet( @FTwainData.AppId,
@FTwainData.SourceId,
DG_IMAGE,
DAT_IMAGELAYOUT,
MSG_SET,
TW_MEMREF(@twImageLayout),
@twRC, FTwainData.DsmEntry
);

Was there any more work done on the SetLayout procedure?

The units are set to inches. The scanner is a Fujitsu 309dc with auto doc feeder.

btw, I'm using Envision for an internal imaging project and it has been working for us beautifully. Thanks.
