LEADTOOLS TWAIN SDK

TWAIN

With LEADTOOLS you can control any scanner, digital camera or capture card that has a TWAIN (32 and 64-bit) device driver. High-level acquisition support is included for ease of use while low-level functionality is provided for flexibility and control in even the most demanding scanning applications.

Overview of LEADTOOLS TWAIN SDK Technology

  • Supports TWAIN 1.x and 2.x drivers
  • Comprehensive multi-thread support for maximum performance
  • Get and set all TWAIN capabilities that the TWAIN driver supports
  • Create custom user interfaces to expose only specific functionality or use the default user interface provided by the TWAIN driver
  • Develop web and cloud-based scanning applications
  • Bypass the user interface for completely automated tasks and batch scanning
  • Utilize events and callbacks to code special per-page processing
  • Show the TWAIN source manager’s selection dialog to select a TWAIN driver, create a custom selection dialog, or select a TWAIN driver programmatically
  • Scan in black and white, halftone, grayscale, palette or full color
  • Control the resolution, position, size, and orientation of the acquired image
  • Use an automated document feeder (ADF) for single and multi-page scanning
  • Scan both front and back of page with duplex scanning
  • Acquire using native, buffered memory, or file transfer mode
  • Buffered memory transfer mode reduces the data transfer bottle neck with JPEG, RLE, BITFIELDS, GROUP 3, GROUP 4 or PackBits compression
  • Load and save current configuration for later use with CustomDS Data
  • Retrieve barcode, patch code, MICR, and other information for each page using Extended Image Information
  • Use LEADTOOLS Fast TWAIN to automatically select optimal device settings for speed
  • Negotiate the TWAIN file system used by digital cameras
  • Native 32 and 64-bit TWAIN binaries
  • Available as .NET (C# & VB) classes, C DLL and C++ classes
