I'm having trouble setting the coordinate of the star are there any better solution for this. I cannot get the the correct shape. Can someone help me on this? The project provides some more shapes often used. All the classes implements Shape interface which allows user to use all the usual methods of Graphics2D like filldrawand create own shapes by combining them.

The advantage is, they are easy to paint and transform. Having said that, the problem you're actually having is the fact that you're not passing the right information to the fillPolygon method. If you take a look at the JavaDocs for Graphics fillPolygonyou'll note that the last parameter is the number of points:.

I find this question is more about math than programming. Active Oldest Votes.Polygon is a closed figure with finite set of line segments joining one vertex to the other. The polygon comprises of set of x, y coordinate pairs where each pair is the vertex of the polygon. The side of the polygon is the line drawn between two successive coordinate pairs and a line segment is drawn from the first pair to the last pair. Output :. Output : drawLine int x, int y, int x1, int y1 : In this method we would connect adjacent vertices with a line segment and also connect the first and last vertex.

Output : Note: The above function are a part of java. Graphics class. Also, these codes might not run in an online compiler please use an offline compiler. The x and y coordinates can be changed by the programmer according to their need.

This state information includes the following properties: The Component object on which to draw. A translation origin for rendering and clipping coordinates.

The current clip. The current color. The current font. The current logical pixel operation function XOR or Paint. Coordinates are infinitely thin and lie between the pixels of the output device. Operations that draw the outline of a figure operate by traversing an infinitely thin path between pixels with a pixel-sized pen that hangs down and to the right of the anchor point on the path.

Operations that fill a figure operate by filling the interior of that infinitely thin path. Operations that render horizontal text render the ascending portion of character glyphs entirely above the baseline coordinate. The graphics pen hangs down and to the right from the path it traverses. This has the following implications: If you draw a figure that covers a given rectangle, that figure occupies one extra row of pixels on the right and bottom edges as compared to filling a figure that is bounded by that same rectangle.

If you draw a horizontal line along the same y coordinate as the baseline of a line of text, that line is drawn entirely below the text, except for any descenders. All coordinates that appear as arguments to the methods of this Graphics object are considered relative to the translation origin of this Graphics object prior to the invocation of the method.

All rendering operations modify only pixels which lie within the area bounded by the current clip, which is specified by a Shape in user space and is controlled by the program using the Graphics object. This user clip is transformed into device space and combined with the device clipwhich is defined by the visibility of windows and device extents.

The combination of the user clip and device clip defines the composite clipwhich determines the final clipping region. The user clip cannot be modified by the rendering system to reflect the resulting composite clip.

The user clip can only be changed through the setClip or clipRect methods. All drawing or writing is done in the current color, using the current paint mode, and in the current font. Since: JDK1.

Viewed 8k times.If an operation that calculates the bounding box of this Polygon has already been performed, such as getBounds or containsthen this method updates the bounding box. Parameters: x - the specified X coordinate y - the specified Y coordinate Since: 1. The bounding box is the smallest Rectangle whose sides are parallel to the x and y axes of the coordinate space, and can completely contain the Polygon. Since: 1.

As of JDK version 1. Returns the bounds of this Polygon. Returns: the bounds of this Polygon. Parameters: p - the specified Point to be tested Returns: true if the Polygon contains the Point ; false otherwise.

Parameters: x - the specified X coordinate to be tested y - the specified Y coordinate to be tested Returns: true if this Polygon contains the specified coordinates x,y ; false otherwise. Determines whether the specified coordinates are contained in this Polygon. Note that there is no guarantee that the returned Rectangle2D is the smallest bounding box that encloses the Shapeonly that the Shape lies entirely within the indicated Rectangle2D.

The bounding box returned by this method is usually tighter than that returned by the getBounds method and never fails due to overflow problems since the return value can be an instance of the Rectangle2D that uses double precision values to store the dimensions.

Note that the definition of insideness can lead to situations where points on the defining outline of the shape may not be considered contained in the returned bounds object, but only in cases where those points are also not considered contained in the original shape. If a point is inside the shape according to the contains point method, then it must be inside the returned Rectangle2D bounds object according to the contains point method of the bounds.

If a point is not inside the shapethen it might still be contained in the bounds object:. The Shape. This means that for some Shapes this method might return true even though the rectangular area does not intersect the Shape.

The Area class performs more accurate computations of geometric intersection than most Shape objects and therefore can be used if a more precise answer is required. This means that for some Shapes this method might return true even though the Rectangle2D does not intersect the Shape. All coordinates that lie inside the rectangular area must lie within the Shape for the entire rectanglar area to be considered contained within the Shape.

This means that for some Shapes this method might return false even though the Shape contains the rectangular area. The Area class performs more accurate geometric computations than most Shape objects and therefore can be used if a more precise answer is required. This means that for some Shapes this method might return false even though the Shape contains the Rectangle2D.
