A method and system is implemented on a host computer for operating upon a window system to update a graphic representation of a selected window item using an image information reading apparatus. The invention mainly includes an image cropping manager for providing a cropped image by cropping an image transmitted from the image capturing manager according to a size requested by a user; and an interface manager for providing a plurality of menu items each associated with at least a dialog box for setting the cropped image as a default image of a selected menu item. The plurality of menu items include Startup Screen, Wall Paper, System LOGO, Icon, Cursor, Screen Saver, Shutdown Screen, Theme, and Restore for updating an associated graphic representation. Eventually, an user can easily establish a personalized windows graphic environment with the assistance of the invention.

The method of the invention involves in finding the width and length of a scanned image in real time and then write the length and width into the header of a bitmap file as soon as the bottom line of the scanned image is found. The width of the scanned image can be computed from the width of the first occurrence of the meaningful image region. The width will be transferred to the scanner to reset the scan width for reading subsequent image data. The length of the scanned image cannot be determined until a bottom line is found. Each meaningful image region can be simultaneously written into the bitmap file while examining the bottom line of the scanned image. To find the bottom line, for each meaningful image region, sample a plurality of line areas to determine if the meaningful image region contains the bottom line. For each meaningful image region examined, sum up the total number of image lines until the bottom line is reached. Eventually, when the bottom line is found, the width and length of the scanned image will be written into the header of the bitmap file.
