Image zoom control using stylus force sensing

An electronic device comprising:

• a screen;
• a memory operable to store a first image;
• and
• a processor, operatively coupled to the memory and the screen and responsive to a stylus location input and a stylus force input;
• the processor operable to display a modified image in a first region of the screen determined from the stylus location input, the modified image dependent upon the first image and having a modification dependent upon the stylus force input.

A non-transitory computer-readable medium having computer-executable instructions that, when executed by a processor, cause the processor to:

• in response to a stylus location input, select a region of the screen;
• determine a first part of the image associated with the selected region of the screen and a second part of the image associated with a region of the screen outside of the selected region;
• in response to a stylus force input, modify the first part of the image to provide a modified first part of the image;
• display the modified first part of the image in the selected region of the screen;
• and
• display the second part of the image on the screen outside of the selected region of the screen.
