TWAIN
SCANNING/CAPTURE
Scanners, Digital Cameras, Capture Cards
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 device driver. High-level acquisition support is provided for ease of use, and low-level functionality is provided for flexibility and control in even the most demanding applications.
Using LEADTOOLS TWAIN capabilities, your application can:
- use the default user interface included with the TWAIN driver.
- create your own user interface to the driver interface.
- bypass the interface entirely for completely automated tasks or batch scanning.
- control the type of image which is acquired (black & white, b/w with halftone, grayscale, color - as supported by the device).
- 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
- use selection dialogs to allow selection of TWAIN source, or select among multiple TWAIN sources in code.
- use of native, buffered memory or file transfer modes when acquiring from a TWAIN device.
- flexibility to get and set all TWAIN v1.9 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 is compressed using JPEG, RLE, BITFIELDS, GROUP 3, GROUP 4 or PACKBITS to reduce the data transfer bottle neck.
- perform the save of the Memory Buffered Transfer data directly to a file.
- get the Extended Image Info that some TWAIN scanner drivers support. 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 v1.9 driver supports. If your TWAIN driver is not v1.9 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 v1.9 specification.
LEADTOOLS TWAIN support gives your applications access to the wide variety of devices which can acquire images via TWAIN from manufacturers like Kodak, Hewlett Packard, Microtek, Logitech, Fuji and many more.
