To set the scanning preferences press ctrl+p and set the starting page number, Mode of page numbering, double page mode if you intend to keep 2 pages at a time, rotation to select the way in which you want the program to rotate the images before conversion. In full automatic rotation mode, one can keep the book in 00 90 180 and 270 degree angle. In partial rotation mode program will scan once to find out the position of the book and then the rotation will be kept. In manual mode one should select the angle. partial and manual mode is faster than full auto rotation mode in ocr process. One can select the number of pages to be scanned at a stretch by setting number of pages in the case of repeated scanning. One can stop all scanning process by pressing ctrl f4.
2. Cam-scan.

one can now use Hovercam or a Webcam to produce text in LIOS. Adjustments with these devices can be made using LIOS-cam-preferences in edit menu. This feature will help to read books and other printed materials such as visiting cards currency and like and also it makes the ocr process very fast and accurate. Please be specific to use devices with auto focusing facility. remember that there is no autorotation in this utility.so for the same reason, support of a stand for the webcam will be highly appreciated.
3. Cam-reader.

is the utility which will give a continuous output as one moves the webcam. First it will create the image and then will produce the text and it will start reading.
