To draw points with the minimum possible radius (one pixel on typicalĪll geometric shapes (such as points, lines, and circles) are drawn using The thickness of the lines and the size of the points to be five times Points, the result will look like a line.įor example, tPenRadius(0.025) makes You will be able to see individual circles, but if you draw 200 such You draw 100 points equally spaced along a horizontal or vertical line, Radius is about 1/200 the width of the default canvas, so that if Is 0.005 and is not affected by coordinate scaling. The pen is circular, so that when you set the pen radius to rĪnd draw a point, you get a circle of radius r.

The points in the polygon are ( x, y).įor example, the following code fragment draws a filled diamond You can draw polygons with the following methods: For example, StdDraw.arc(0.0, 0.0, 1.0, 0, 90)ĭraws the arc of the unit circle from 3 o'clock (0 degrees) to 12 o'clock (90 degrees). Polar (counterclockwise angle from the x-axis)Īnd represented in degrees. The arc is from the circle centered at ( x, y) of the specified radius.

arc(double x, double y, double radius, double angle1, double angle2).

You can draw circular arcs with the following method:

filledRectangle(double x, double y, double halfWidth, double halfHeight).

filledSquare(double x, double y, double radius).

filledEllipse(double x, double y, double semiMajorAxis, double semiMinorAxis).

filledCircle(double x, double y, double radius).

The methods above trace outlines of the given shapes. The convention for drawing squares and rectangles is parallel to those forĭrawing circles and ellipses, but may be unexpected to the uninitiated. The size of a square or rectangle is specified by its half-width or half-height. Specified by the lengths of its semi-major and semi-minor axes. The size of a circle is specified by its radius and the size of an ellipse is The location is always specified by the x- and y-coordinates

rectangle(double x, double y, double halfWidth, double halfHeight)Īll of these methods take as arguments the location and size of the shape.

square(double x, double y, double halfLength).

ellipse(double x, double y, double semiMajorAxis, double semiMinorAxis).

circle(double x, double y, double radius).

You can draw squares, circles, rectangles, and ellipses using Squares, circles, rectangles, and ellipses. (between 0 and 1 and by default) or the points and lines will not be visible. The x- and y-coordinates must be in the drawing area

line(double x1, double y1, double x2, double y2).

You can draw points and line segments with the following methods: The methods StdDraw.line() and StdDraw.point()ĭraw lines and points the methods tPenRadius()Īnd tPenColor() control the line thickness and color. This program illustrates the two main types of methods in standardĭrawing-methods that draw geometric shapes and methods that If you compile and execute the program, you should see a windowĪppear with a thick magenta line and a blue point. Now, cut-and-paste the following short program into your editor: If you used our autoinstaller, you should be all set.Īnd add to your Java classpath or downloadĪnd put a copy in your working directory. To use this class, you must have StdDraw.class in your User interaction via the keyboard and mouse. Standard drawing also includesįacilities for text, color, pictures, and animation, along with It uses a simple graphics model thatĪllows you to create drawings consisting of points, lines, squares,Ĭircles, and other geometric shapes in a window on your computer and

The StdDraw class provides a basic capability forĬreating drawings with your programs.
