Abstract
In a graphical application which allows an image to be displayed according to a display scale, a method of adjusting the display scale during modification of the image. The method responds to user selection of a modification to be performed on the image by storing the current display scale. Then the current display scale is automatically adjusted during modification of the image and in response to user completion of the modification the stored display scale is automatically returned. In a preferred embodiment, the velocity of a pointing device is measured and the display scale is adjusted as a function of the velocity of the pointing device during graphical modification and before the display of the image is re-centered on the pointing device position.
