Use Rectangle2D.Double, Ellipse2D.Double, Line2D.Double from the package instead of Rectangle, Ellipse, Line.If you can't use the simple graphics library, make these changes in your program. Note that the row index is the y-coordinate and the column index is the x-coordinate that is, grays is the gray level of pix.getColor(x, y). Why not an array of colors? This method is used for some practice assignments with two-dimensional arrays, and an array of int is easier to work with than an array of Color values. Here, x goes from 0 to pic.getWidth() - 1 and y goes from 0 to pic.getHeight() - 1.įinally, you can get a two-dimensional array of gray levels between 0 and 255 with the call int grays = pic.getGrayLevels() This one-dimensional index is useful if you simply want to iterate over all pixels and transform them in a uniform way, for example to make all pixels in an image redder.Īlternatively, you can access pixels by their x and y coordinates, for example Color c = pic.getColorAt(x, y) It is the same as pic.getWidth() * pic.getHeight(). The index goes from 0 to pic.pixels() - 1, where pic.pixels() is the total number of pixels in the image. You can use a single integer index to access the pixels. You access the pixels of a picture with the methods getColorAt and setColorAt. If you want to do the latter, you can construct an empty picture as Picture pic = new Picture(width, height) The Picture class can be used to add images to scenes, or to write programs that manipulate pixels. By taking repeated snapshots, you can show movement.

Any newer drawings appear at full intensity. This can be useful when you want to see a picture before you change its pixels.Ĭanvas.snapshot() takes a snapshot of the canvas, fades it, and sets the faded image as the canvas background. You don't need to worry about it, but the Canvas class has a couple of convenience methods.Ĭanvas.pause() pops up a dialog so that the drawing is stopped until the user dismisses the dialog. For convenience, getMaxX and getMaxY return the coordinates of the bottom right corner.Īll shapes are drawn on an object of type Canvas. The getX and getY methods return the coordinates of the top left corner. You can get the the width and height of any shape with the getWidth, and getHeight methods. To construct a picture, provide the name of the image file, and then move it to the desired location with the translate method. For text, specify the top left corner and the string to be drawn. Rectangle box = new Rectangle(x, y, width, height) Įllipse egg = new Ellipse(x, y, width, height) įor a line, specify the end points.

For an ellipse, give those values for the bounding box of the ellipse. To construct a rectangle, give the x- and y- positions of the top left corner, the width, and the height. For example, if you view a Rectangle object in BlueJ and change the color, position, or size (with setColor, translate, or grow), the shape gets updated right away. box.translate(20, 30) // Move by 20 pixels to the right, 30 pixels downĮgg.grow(5, 5) // Grow by 5 pixels on all four sidesĪll changes to a shape are instantaneous. You can change a shape by translating (i.e., moving) or growing it. (Filling fills the entire shape with its color.) Rectangle box = new Rectangle(5, 10, 60, 80) Įllipse egg = new Ellipse(100, 100, 40, 60)

Then add Rectangle, Ellipse, Text, Line, and Picture as needed.Ĭonstruct a shape and then either draw it or fill it. You always need Shape, Canvas, and Color. Simply include the classes that you need (or, if you prefer, all classes) in your project. Here, you will find an overview of the library, the API documentation, and a cookbook for translating your simple graphics programs to standard graphics. It is similar to the standard Java graphics library, but it works better with BlueJ. I created the Simple Java Graphics library for the CS46A Udacity course.
