EZTwain

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;
begin
    fileName := 'c:\multipage.pdf';
    TWAIN_LogFile(1);
    TWAIN_SetHideUI(1);
    if TWAIN_OpenDefaultSource()=1 then
    begin
        TWAIN_SelectFeeder(1);
        TWAIN_EnableDuplex(0);
        TWAIN_SetPixelType(0);
        TWAIN_SetBitDepth(1);
        TWAIN_SetResolution(300);
        TWAIN_SetAutoScan(1);
        TWAIN_AcquireMultipageFile(self.Handle, fileName)
    end
    else
        TWAIN_ReportLastError('Unable to scan.')
    end
