- providing an original document comprising a plurality of pixels, and a having a width in pixels and a height in pixels;
calculating a reduction ratio equal to a ratio of the original document width to the digital handheld device screen width;
processing color values of a two dimensional array of pixels of the original document;
building a reduced document comprising a plurality of pixels, and having a width in pixels equal to the width of the original document divided by the reduction ratio and a height in pixels equal to the height of the original document divided by the reduction ratio, a color value of each pixel of the reduced document determined by said processing; and
displaying the reduced electronic document on the digital handheld device screen.

Abstract
A method of displaying an electronic document on a digital handheld device first calculates a reduction ratio equal to a ratio of an original document width to the digital handheld device screen width. The method then calculates color values of pixels in a reduced document by processing color values of an array of pixels in the original document. The method builds the reduced document having a size related to the original document by the reduction ratio. Finally, the method displays the reduced electronic document on the digital handheld device screen, and allows a user to switch between the original and reduced documents.
