1. An information handling system comprising:
- a gesture sensitive interface; and
a processor configured to;
receive inputs from the gesture sensitive interface corresponding to first and second interaction points;
determine a relative motion between the first and second interaction points;
obtain a velocity of the relative motion based on an average velocity of the interaction points;
determine if the velocity exceeds a threshold;
determine a scaled magnification necessary to achieve a specified height for the rendered text of a document based on the font size and display size; and
scale an image on a display from an initial magnification to the scaled magnification to achieve the specified height for the rendered text when the velocity exceeds the threshold.

Abstract
An information handling system includes a gesture sensitive interface and a processor. The processor is configured to receive inputs from the gesture sensitive interface corresponding to first and second interaction points, determine a relative motion between the first and second interaction points, and obtain a velocity of the relative motion. The processor is further configured to determine if the velocity exceeds a threshold, and scale an image on a display from an initial magnification to a predetermined magnification when the velocity exceeds a threshold.
