Abstract
Disclosed examples include drawing apparatus and methods of rendering lines on a display screen, in which a first angle is determined that corresponds to a hand drawn line created by a user on the display screen, and a new line is rendered on the display screen to represent the hand drawn line created by the user. The new line is selectively rendered parallel or perpendicular to an existing line on the display screen at least partially according to the first angle using the processor.
Claims23
A method of rendering lines on a display screen, the method comprising:
- using a processor, determining a first angle corresponding to a hand drawn line created by a user on the display screen;
- and
- using the processor, rendering a new line on the display screen to represent the hand drawn line created by the user, the new line being selectively rendered parallel or perpendicular to an existing line rendered on the display screen at least partially according to the first angle using the processor.
A non-transitory computer readable medium with computer executable instructions for rendering lines on a display screen, the computer readable medium comprising computer executable instructions for:
- determining a first angle corresponding to a hand drawn line created by a user on the display screen;
- and
- rendering a new line on the display screen to represent the hand drawn line created by the user, the new line being selectively rendered parallel or perpendicular to an existing line rendered on the display screen at least partially according to the first angle.
A drawing apparatus, comprising:
- a processor;
- a display screen operatively coupled with the processor;
- a user interface to provide input data associated with a hand drawn line created by a user;
- the processor operative to execute program instructions to:
- determine a first angle corresponding to a hand drawn line created by the user on the display screen, and
- render a new line on the display screen to represent the hand drawn line created by the user, the new line being selectively rendered parallel or perpendicular to an existing line rendered on the display screen at least partially according to the first angle using the processor.
