- This program is the .NET library completely written in C#
- AnyCPU, x86 and x64 mode support
- Control any scanner or device compatible with TWAIN 1.x / 2.x specification
- Enumerate and select a scanner
- Acquire image from scanner
- Preprocess acquired image
- Save acquired image to a file or database
- Upload acquired image to HTTP, HTTPS or FTP server
TWAIN device selection- Enumerate TWAIN devices available in the system
- Select the TWAIN device:
- Using the standard TWAIN device selection dialog
- Using your custom TWAIN device selection dialog
- Programmatically from code
Image scanning- Acquire image from scanner:
- Using the standard user interface (UI) of scanner
- Using your custom user interface
- Without user interface
- With or without the progress indicator of scanner
- With your custom progress indicator - available for the buffered memory transfer mode only
- Acquire image asynchronously or acquire image synchronously
- Cancel image acquisition
- Acquire a black-white, halftone, grayscale, palette or color image
- Scan the whole page or page region
- Scan front and/or back of page using duplex scanning
- Use the automatic document feeder (ADF) for multipage scanning
- Specify the desired format, size, position, orientation, resolution, brightness, contrast of acquired image
- Use the native or buffered memory transfer mode to:
- acquire image as System.Drawing.Bitmap object
- acquire image as System.Windows.Media.Imaging.BitmapSource object
- Use the file transfer mode to acquire image directly to a file
- Control any TWAIN capability supported by device
- Retrieve the extended information (page number, page side, barcode, patch code, MICR, etc) about acquired image
- Serialize and deserialize the scanner capability settings to XML file
- Create predefined session setups for mid- and high-volume scanners
- Skip blank pages while scanning
- Use the Dual Stream feature (make some snapshots of each acquired page) of Kodak scanner
Image preprocessing- Preprocess the acquired image before saving: invert, rotate, crop, resize canvas, despeckle, deskew, border detection, blank page detection, change brightness and contrast
Image saving- Save the acquired image to a BMP, JPEG, PNG, GIF, TIFF file
- Save the acquired image to a PDF or PDF/A document
- Add the acquired image to a multipage TIFF file
- Add the acquired image to a PDF or PDF/A document
- Save the acquired image into database
Image uploading- Upload the acquired image to HTTP or HTTPS server
- Upload the acquired image to FTP server
