Zusammenfassung:A method for implementing a brush stroke of an electronic whiteboard marker, a storage medium, and an electronic whiteboard are disclosed. The method includes: obtaining touchpoint coordinates in a writing process, and constructing a Bezier curve equation based on the touchpoint coordinates; dividing a handwriting curve into continuous handwriting units equidistantly based on the Bézier curve equation; connecting adjacent ones of the handwriting units to form a closed compensation zone; and filling the compensation zone with a handwriting-related color. In this way, different brush strokes such as horizontal, vertical line, left-falling, and right-falling strokes can be formed, and a toothed border formed by superposition of the handwriting units can be effectively covered, making a boundary contour smoother.
