Drawing control device, laser-light emitting system, drawing method, and computer program product

A drawing method comprising:

• generating, by a fill-stroke generating unit, a fill stroke that includes a plurality of strokes that fill a drawing area;
• generating, by a shape-stroke generating unit, a shape stroke, said shape stroke being a stroke of a shape to be formed on the drawing area;
• detecting, by a first detecting unit, an overlap portion where the fill stroke and the shape stroke overlap with each other;
• modifying, by a modifying unit, the fill stroke to obtain a drawing stroke by removing the overlap portion from the fill stroke and by removing the shape stroke;
• generating, by a drawing-instruction generating unit, a drawing instruction for drawing each stroke in the drawing stroke;
• and
• controlling, by a drawing control unit, a drawing device by using the drawing instruction to cause the drawing device to draw the drawing stroke on an object, the drawing device being a device for drawing visual information on the object by transferring energy to the object.

A computer program product comprising a non-transitory computer-readable medium having computer-readable program codes embodied in the medium for processing information in a drawing control device that includes a fill-stroke generating unit, a shape-stroke generating unit, a first detecting unit, a modifying unit, a drawing-instruction generating unit, a drawing control unit, and a second detecting unit, the program codes when executed causing a computer to execute:

• generating, by the fill-stroke generating unit, a fill stroke that includes a plurality of strokes that fill a drawing area;
• generating, by the shape-stroke generating unit a shape stroke, said shape stroke being a stroke of a shape to be formed on the drawing area;
• detecting, by the first detecting unit, an overlap portion where the fill stroke and the shape stroke overlap with each other;
• modifying, by the modifying unit, the fill stroke to obtain a drawing stroke by removing the overlap portion from the fill stroke and by removing the shape stroke;
• generating, by the drawing-instruction generating unit, a drawing instruction for drawing each stroke in the drawing stroke;
• and
• controlling, by the drawing control unit, a drawing device by using the drawing instruction to cause the drawing device to draw the drawing stroke on an object, the drawing device being a device for drawing visual information on the object by transferring energy to the object.
