Full Scanning Program using ADF

Hi

i Need a full Program that uses the scanner's Auto document feeder(ADF) and show the scanned pictures on the form as thumbnails.
Also i want to set the number of documents to scan, and after that the scanner should stop.
i don't want the scanner source select to be shown to the user, i want it to be selected from code. or at least once
all the scanned Pictures should be saved as files in a temporary folder specified in Code.
i don't want to use any outside component unless it's free and downloadable.
i also want to be able to select if i want to scan from the ADF or the flat pad.

I have windows XP SP2, using HP Scanjet 8300 Series, I'm Using Delphi 6.0

points will go directly to the first working program with my requirements

Appreciate your Help, thanks in advance and best regards,

i forgot to say if it is possible to specify the resolution and the scan mode(Gray scale, black & white,24 bit color,...)

Hi,

Nearly a complete application you're asking, no ? A clone of the HP utility provided with the hardware. ;)

first go to:
http://delphitwain.sourceforge.net/
"Delphi Twain is my latest contribution to the Delphi community. This library consists in a implementation of Twain features for Borland Delphi tool."

Have a look at about on this subject:

http://delphi.about.com/od/graphics/l/aa030299.htm

and

http://www.twain.org/index.html

You can also download a compo from jedi: ftp://ftp.delphi-jedi.org/api/twain19.zip
(http://www.delphi-jedi.org/apilibrary.html)

Dear Bernani,

i already have visited these sites, I've downloaded Delphi Twain, but i didn't know how to select the scanner source(Flatpad or ADF), the example generates some errors when you try to use the"Send Command" Screen and i don't know why.

www.Twain.org i couldn't get any use of it, besides there is a lot of documents and i don't have enough time to read them, and this is why i asked for a full project.

ftp://ftp.delphi-jedi.org/api/twain19.zip , the link is not working

Lead tools is not for free

i need a full source project that does what i need.
