That’s a good idea Thierry – I just dumped the custom DS data from my fi-5110C, and it’s in INI file format. Below is an excerpt, notice the Endorser section. I think you could save this to a file and use the Windows Profile functions to edit it. Shameless plug: This would be especially easy with EZTwain Pro, which has single functions to get and set the CustomDsData…
[CustomHead]
Driver=FJTW32.DS
Version=V9.18
Scanner=fi-5110Cdj
DataLength=04831
StructureRevision=5.6
[Common]
ImageScanner=fi-5110Cdj
ReverseImageForm=0
BackGroundCompensate=0
…
EnableEndorse=0
EndorseSurface=0
EndorseYOffset=0
EndorseDirect=0
InitialCount=0
CounterStep=0
CounterMode=0
EndorseString=
On the other hand, I’d understand if you wanted to use standard or semi-standard TWAIN capabilities, since the CustomDsData is technically ‘opaque’ – you can’t count on anything in it staying the same from one version of the driver to the next.
