This way the receiving application (if it supports barcode recognition) can recompose single-page or multi-page documents correctly. These pages don't have to be scanned as with a feeder scanner but are inserted purely virtual during transfer to the calling application. You can scan images using a TWAIN-compliant image processing application. With the option "Insert barcode" (tab: Options) you can insert a seperating barcode page between the individual documents. This scanner is a TWAIN-compliant device. Instead of passing the scanned documents into a target folder or via Email, you can send the pages with the button "Twain Transfer" via TWAIN back to the calling application.
Please note: As for sceye-Autoscan a license is required to use sceye via the TWAIN interface.Īpart from the functions known from sceye-Autoscan two special features are availble when you access this driver: Please refer to the chapter "sceye-Autoscan" for closer information about its operation.
The driver can only be used when Autoscan is displayed as TWAIN dialogue. When selecting the TWAIN source, this driver is called "sceye-Autoscan" (with version number). The driver interface described herein is the TWAIN driver that has been developed for your scanner. The TWAIN scanning interface can be accessed from any TWAIN scanning application you have installed on the computer. The scan is immediately started with the scan button and the result is redelivered to the calling application. TWAIN is a widely recognized standard that comp uters use to receive images from scanners and digital cameras.
There is also a contrast controller below the preview window to adjust the appropriate contrast setting in the live preview fast and easily.Īs in the sceye Explorer you can draw a frame right onto the preview image to define a manual crop. Apart from the basic settings (color mode, resolution, filter) you can control here advanced functions such as auto crop, laser and lighting. The same settings as in sceye Explorer are also available in the embedded menu of the preview window. 2) Restart browser 3) In the drop-down menu you will see list scanners, if not, sure that you installed device or you can set 'Show Twain' as virtual scanner for test.
1) Install extension, tap 'Install' and complete all steps. In the following of course only the use of the TWAIN dialogue is relevant for operation. Extension for scan paper documents from scanner device and send base64 on page web application. The driver can be used with or without TWAIN dialogue. When you select it as a scanning source, the UniTwain interface appears, allowing you to import documents, images, snapshots from cameras, and even scans from other scanners. The TWAIN driver appropriate for the given scanner must be installed. UniTwain, a virtual scanner, appears in your application just like any physical scanning device. The TWAIN scan engine allows you to capture images from a scanner using TWAIN drivers. When selecting the TWAIN source, this driver is simply called "sceye" (with version number). How does the universal TWAIN importer work 1.
There are two TWAIN drivers for Windows and one TWAIN driver for Mac available, tailored for sceye.
