Using Graphic Shapes. You can add various graphic shapes to images. From the Viewer, select an image. Click Show Graphics. Artisan: Shapes Library. Our unique Artisan Shopify theme includes an easy method for adding some visual interest to your shop background! Browse through the shapes below and note the name of the one you want to use; then enter that name in the Theme Editor settings for that section. You can also control the size and color, and display.

I created the Simple Java Graphics library for the CS46A Udacity course. It is similar to the standard Java graphics library, but it works better with BlueJ. Here, you will find an overview of the library, the API documentation, and a cookbook for translating your simple graphics programs to standard graphics.

Simply include the classes that you need (or, if you prefer, all classes) in your project. You always need Shape
, Canvas
, and Color
. Then add Rectangle
, Ellipse
, Text
, Line
, and Picture
as needed.
Construct a shape and then either draw
it or fill
it. (Filling fills the entire shape with its color.)
You can change a shape by translating (i.e., moving) or growing it.
All changes to a shape are instantaneous. 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.
To construct a rectangle, give the x- and y- positions of the top left corner, the width, and the height. For an ellipse, give those values for the bounding box of the ellipse.
For a line, specify the end points. For text, specify the top left corner and the string to be drawn.
To construct a picture, provide the name of the image file, and then move it to the desired location with the translate
method.
You can get the the width and height of any shape with the getWidth
, and getHeight
methods. The getX
and getY
methods return the coordinates of the top left corner. For convenience, getMaxX
and getMaxY
return the coordinates of the bottom right corner.
All shapes are drawn on an object of type Canvas
. You don't need to worry about it, but the Canvas
class has a couple of convenience methods.
Canvas.pause()
pops up a dialog so that the drawing is stopped until the user dismisses the dialog. This can be useful when you want to see a picture before you change its pixels.
Canvas.snapshot()
takes a snapshot of the canvas, fades it, and sets the faded image as the canvas background. Any newer drawings appear at full intensity. By taking repeated snapshots, you can show movement.
The Picture
class can be used to add images to scenes, or to write programs that manipulate pixels.
If you want to do the latter, you can construct an empty picture as
You access the pixels of a picture with the methods getColorAt
and setColorAt
. You can use a single integer index to access the pixels. Zack and cody pizza party pickup unblocked.
The index goes from 0 to pic.pixels() - 1
, where pic.pixels()
Office 2019 windows 7 32. is the total number of pixels in the image. It is the same as pic.getWidth() * pic.getHeight()
.
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.
Alternatively, you can access pixels by their x
and y
coordinates, for example
Here, x
goes from 0 to pic.getWidth() - 1
and y
goes from 0 to pic.getHeight() - 1
.
Finally, you can get a two-dimensional array of gray levels between 0 and 255 with the call
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.
Note that the row index is the y-coordinate and the column index is the x-coordinate; that is, grays[y][x]
is the gray level of pix.getColor(x, y)
.

If you can't use the simple graphics library, make these changes in your program.
Rectangle2D.Double
, Ellipse2D.Double
, Line2D.Double
from the java.awt.geom
package instead of Rectangle
, Ellipse
, Line
main
, and change all calls shape.draw()
to g2.draw(shape)
and shape.fill()
to g2.fill(shape)
. However, for Text
objects, there is no analogous object. Instead, use g2.drawString(x, y, messageString)
.java.awt.Color
instead of the Color
class. Replace shape.setColor(c);
with g2.setColor(c);
just before drawing or filling the shape.Fgteev hello neighbor mod kit. Now you probably know why I supply the simple library instead :-)
The Shapes Library panel manages libraries of reusable shapes. You can create your own libraries, save shapes, and reuse them throughout multiple projects.
Graphic includes a few built-in example libraries to help you get started. The included shapes can be used to add symbols or annotations to an existing design, create floor plan layouts, and even design iPhone app mockups.
Saved shapes can be organized into libraries of related objects. To switch between libraries, simply select one from the pop-up menu. The shapes from the selected library will appear in the panel below.
To add a shape to a design simply drag it from the list onto the canvas.
