TWAIN Scanning SDK
Scanners, Digital Cameras,
Capture Cards
New TWAIN 2.0 (32 and 64-bit) support.
LEADTOOLS provides a powerful set of tools spanning the full spectrum of digital imaging, including in-depth support for image acquisition through industry standard interfaces from a wide variety of hardware devices.
With LEADTOOLS you can control any scanner, digital camera or capture card that has a TWAIN or WIA (32 or 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 applications.
Using LEADTOOLS Scanning capabilities, your application can:
- Use the default user interface included with the TWAIN driver.
- Scan and save images to SharePoint
- Create your own user interface to the driver interface to expose only the functionality you want to expose.
- Negotiate the TWAIN File System used for digital cameras.
- Bypass the interface entirely for completely automated tasks or batch scanning.
- Control the type of image as supported by the device which is acquired (black & white, b/w with halftone, grayscale, color, etc...).
- Control the resolution (dpi), position, size, and orientation of the image to be acquired.
- Use the automated document feeder for single and multi-page scans, including support for duplex scanning.
- Use supplied events and callbacks to code your own special per-page processing.
- Selection dialog to select a TWAIN source or select a TWAIN source in code.
- Use of native, buffered memory or file transfer modes when acquiring from a TWAIN device.
- Flexibility to get and set all TWAIN capabilities that the device's TWAIN driver supports.
- Save of the device's TWAIN capability settings to a template file, helping to save multiple settings of sources and load them as needed.
- Buffered memory transfer mode includes compression support. The scan data can be compressed using JPEG, RLE, BITFIELDS, GROUP 3, GROUP 4 or PACKBITS to reduce the data transfer bottle neck.
- Automatic selection of optimal device settings for speed. See LEADTOOLS Fast Twain for more information.
- Save buffered memory transfer data directly to a file.
- Get the Extended Image Info that some TWAIN scanner driver supports. For example, if the scanner driver supports reading barcodes or patch codes, then that information could be retrieved via LEADTOOLS TWAIN support.
With the LEADTOOLS TWAIN support, you can do anything that your TWAIN v2.0 driver supports. If your TWAIN driver is not v2.0 or does not support a functionality listed above, then LEADTOOLS will support all of the features that the driver has that are compatible with the TWAIN specification.
LEADTOOLS TWAIN support gives your applications access to the wide variety of devices which can acquire images via TWAIN from manufacturers such as Kodak, Hewlett Packard, Microtek, Logitech, Canon and Fujitsu.
