How do you fill a polygon with color in Java?
g. fillPolygon(x, y, 6); Draws and fills a polygon with a previously set color.
How do you change the fill color in Java?
To fill rectangles with the current colour, we use the fillRect() method. In the example we draw nine coloured rectangles. Graphics2D g2d = (Graphics2D) g; There is no need to create a copy of the Graphics2D class or to reset the value when we change the colour property of the graphics context.
How do you fill a triangle with color?
3 Answers. Make a Polygon from the vertices and fill that instead, by calling fillPolygon(…) : // A simple triangle. x[0]=100; x[1]=150; x[2]=50; y[0]=100; y[1]=150; y[2]=150; n = 3; Polygon p = new Polygon(x, y, n); // This polygon represents a triangle with the above // vertices.
How do you fill a polygon in Graphics?
Filling a Polygon
- find intersections of the current scan line with all edges of polygon.
- sort intersections by increasing x coordinate.
- moving through list of increasing x intersections. parity bit = even (0) each intersection inverts the parity bit. draw pixels when parity is odd (1)
How do you fill an object in Java?
fill(object[] a, int fromIndex, int toIndex, object val) method assigns the specified Object reference to each element of the specified range of the specified array of objects. The range to be filled extends from index fromIndex, inclusive, to index toIndex, exclusive.
What is polygon in Java?
The Polygon class encapsulates a description of a closed, two-dimensional region within a coordinate space. Internally, a polygon comprises of a list of (x,y) coordinate pairs, where each pair defines a vertex of the polygon, and two successive pairs are the endpoints of a line that is a side of the polygon.
What are the different methods of polygon filling?
There are two methods by which we can identify whether particular point is inside an object or outside.
- Odd-Even Rule.
- Nonzero winding number rule.
