The operating principle of a scanner is as follows:

* The scan through the document line by line;
* Each line is broken down into " basic issues " , correspond to pixels .
* A sensor analyzes the color of each pixel ;
* The color of each pixel is decomposed into three components ( red, green , blue) ;
* Each color component is measured and represented by a value. For quantification of 8 bits , each component has a value between 0 and 255.

You can crop an image before the scan by clicking on Survey in the dialog box Rescan Then, in the preview area , dragging the handles of the cutting tool to resize the image. If you scan the page contains multiple images , you can save each image in a separate file by selecting the checkbox Browse or scan images as separate files.
