You select color and paint mode, and call methods of the Graphics class such as drawRect or fillOval. You can easily produce a wide variety of shapes. You have control over the stroke, the pen that traces shape boundaries.

Float to support double- and float-precision. High-quality 2D rendering e. Hence, double and float subclasses are introduced in Java 2D for better accuracy and smoothness. The earlier int-precision classes, such as Point and Rectangle are retrofitted as a subclass of Point2D and Rectangle2D.

Float are kept in package java. GeneralPath class represents a geometric path constructed from straight lines, quadratic and cubic curves. Source codes of java.

Nested Class Summary

Point2D Point2D is an abstract class that cannot be instantiated. It declares the following abstract methods: Hence, it is designed as an abstract class, instead of interface.

Point2D does not define any instance variable, in particular, the x and y location of the point. This is because it is not sure about the type of x and y which could be int, float or double.

The instance variables, therefore, are left to the implementation subclasses. Three subclasses were implemented for types of int, float and double, respectively. Float How to design these subclasses? Point is the subclass for int-precision. It declares instance variables x and y as int, provides implementation to the abstract methods declared in the superclass, and provides some additional methods.

Point is a legacy class since JDK 1. For higher-quality and smoother graphics e. Java 2D, hence, introduced float-precision and double-precision points. Double for double-precision point and Point2D. Float for float-precision point are, however, implemented as nested public static subclasses inside the Point2D outer class.

Recall that nested class or inner class can be used for: Keeping codes together and namespace management. In this case, it is used for namespace management, as there is no access-control involved.

In other words, they can be referenced via the classname as Point2D. Float, and used directly without instantiating the outer class, just like any static variable or method e. They are subclasses of Point2D, and thus can be upcasted to Point2D.

Float and Point to superclass Point2D. Float as ordinary classes with a slightly longer name. These classes were designed before JDK 1.

The Shape interface declares abstract methods contains and intersectswhich are useful in game programming for collision detection: Polygon class was retrofitted to implement Shape interface.

A Stroke object implements java. Java 2D provides a built-in java.

A Paint object implements the java. RED, Color. Working with Bitmap Images Reference: The dimension of the image is represented by its width and length in pixels. In Java, the origin 0, 0 of an image is positioned at the top-left corner, like all other components.

Most of the image display and processing methods work on java. Image is an abstract class that represent an image as a rectangular array of pixels.

The most commonly-used implementation subclass is java. BufferedImage, which stores the pixels in memory buffer so that they can be directly accessed.

Image is typically read in from an external image file into a BufferedImage although you can create a BufferedImage based on algorithm.The following example will read an image file named ““, convert it into byte array, and then reuse the converted byte array, and convert it back to a new BufferedImage, and save it back into a new name ““.

package; import Goal¶. Whenever you work with video feeds you may eventually want to save your image processing result in a form of a new video file.

For simple video outputs you can use the OpenCV built-in VideoWriter class, designed for this. UnFreez is a small program for creating animated GIF files but is short of more advanced features. Gimp a free software raster graphics editor good for image editing.

And it's definetly not worth buying. Transform is key in game programming and animation! An affine transform is a linear transform such as translation, rotation, scaling, or shearing in which a straight line remains straight and parallel lines remain parallel after the transformation.

Description. You’re making a music video for an acid rock band. Far out man! Of course they want visual effects with fractals, because they’ve googled fractals, and they’re super course, they don’t know the mad programming needed to make these fractals.

Similar to the images on, make images where each pixel is a unique color (no color is used twice and no color is missing).. Give a program that generates such an image, along with a screenshot or file of the output (upload as PNG). Create the image purely algorithmically.
