DynaRithmic TwainSave              

TwainSave is a Win32 command-line scanning utility from that allows you to acquire images from any TWAIN compatible device, and save the images to a variety of image formats. The supported formats are

• BMP
• JPEG
• JPEG-2000
• TIFF (Group3, Group4, JPEG, LZW, Packbits, Flate, Uncompressed)
• GIF
• PCX
• PNG
• Targa
• Windows meta file (WMF)
• Enhanced Windows meta file (EMF),
• Adobe Photoshop (PSD)
• Adobe Acrobat (PDF)
• Postscript Level 1 and Level 2

Also available are multipage TIFF, PCX, PDF, and PostScript files.  When producing Acrobat PDF files, TwainSave has various options including setting the producer, keywords, encryption, and other useful PDF options.

Also, TwainSave contains many options to acquire images:

• Use the flatbed or automatic document feeder.
• Specify color and bit-depth of the images acquired.
• Job and batch control for TWAIN devices that support job control.
• Acquire images with or without the device user interface (fully TWAIN compliant devices only).
• Optional logging features for diagnostic purposes.

and many more options.

Since TwainSave is a command-line utility, end-users as well as programmers can easily utilize TwainSave in their programs to initiate Twain image retrieval.  If the programmer desires even more control of TWAIN image retrieval, it is highly recommended that the DynaRithmic TWAIN Library be used for more programmatic control of the Twain devices.

For example, to initiate a file transfer from the TWAIN device to a BMP file, it is as simple as stating this on the Win32 command-line:

twainsave -f test.bmp

This simple command

• Displays the TWAIN "Select Source" dialog box, allowing you to select the TWAIN scanner, digital camera, etc. you would like to communicate with
• Once the TWAIN device has been selected, the device's user interface will appear, allowing you to start the device that was selected so as to retrieve the images (for example, if the device is a scanner, the scanner will start to scan a page).
• Once the image has been retrieved, it is saved to a file called "test.bmp".
• TwainSave then automatically shuts down (there is also an option to keep TwainSave running after pages have been retrieved)

Please note:

TwainSave will work the best on devices that adhere to the TWAIN compliancy specifications.
