WebOct 8, 2024 · What is the Scan line algorithm for polygon filling . In computer graphics, a scan line algorithm is a process of filling regions of a polygon that are geometrically defined by the coordinates of vertices of this polygon graph. This algorithm is specially used for the region filling just like the boundary-fill and flood-fill algorithm. WebThe header file graphics.h contains line() function which is used to draw a line from a point(x1, y1) to point(x2, y2) i.e. (x1, y1) and (x2, y2) are end points of the line. The function line() draws a line on the graphics screen between two specified points. So this function requires four parameters namely x1, y1, x2, and y2 to represent two ...
