Java 2D Graphics
Overview
In this project you will create 3 simple, images or your choice and use Java 2D graphic methods to
rotate, scale and translate each of the images.
Requirements:
1. Using Netbeans or Eclipse, develop a Java 2D graphics application that creates 3 images. The
images should have the following specifications:
a. Size: minimum 25×25 pixels, larger images are Okay
b. Type: Color (consists of two or more colors)
c. Simple form or shape (Hint: consider a letter or number, or even simple shapes such as
crossing lines, rectangles, or circles
d. You should generate the image inside of separate methods and store them as 2D arrays.
2. Use Java 2D graphics to display your original images.
3. For each image use the existing Java 2D graphics transformation methods to translate, rotate
and scale each object. You should perform the following transformations on each image:
a. Translate -5 in x direction, Translate +7 in the y direction.
b. Rotate 45 counter clockwise.
c. Rotate 90 clockwise
d. Scale 2 times for the x component, scale 0.5 times for the y component
e. Each of these transformations should be displayed in sequence with the images always
starting from the previous transformation as opposed to the original image.
f. Use Java 2D graphics to display each transformation for each image. (Hint: review the
Project 1 template for a good start for this project.)
4. All Java source code should be written using Google Java style guide.
5. Prepare, conduct and document a test plan verifying your application is working as expected.
This plan should include a test matrix listing each method you tested, how you tested it, and the
results of testing.
