EZTwain Pro - TWAIN from Delphi™

Overview  Download  Licensing  Features  Code Wizard  Stories  User GuidePDF file

Precise control of TWAIN scanning and image capture for Delphi programmers. EZTwain Pro 3 includes a complete Delphi interface unit (eztwain.pas) translated automatically from the eztwain.h C/C++ header file. See the EZTwain Pro product page, or download the developer kit and look in the Delphi sub-folder.

Our Code Wizard (part of the EZTwain toolkit) now generates Delphi code. For example, if you tell the Code Wizard you want to scan all the pages in a document feeder at 300 DPI in black & white, simplex (front side only), and write them into a single PDF file, here is the code it generates:

var fileName: array [0..260] of Char;
    fileName := 'c:\multipage.pdf';
    if TWAIN_OpenDefaultSource()=1 then
        TWAIN_AcquireMultipageFile(self.Handle, fileName)
        TWAIN_ReportLastError('Unable to scan.')

If you wish to redistribute the EZTwain Pro DLLs with an application, or within an organization, see the EZTwain Pro Licensing Page.
