Image Filters

This project contains a number of image filters written in Java as well as an interface for using them.

Usage

After cloning the repo, compile the Main class. Then run it with the input file, output file, and desired filters as arguments.

javac Main.java
java Main input.png output.png --rainbow --artifacter

The input file can be any file ImageIO can read. The output file must be a PNG.

Filters

Rainbow

This filter adjusts the the hue of pixels in the image based on where the pixel is horizontally. The result is a rainbow like effect.

The command line argument for this filter is --rainbow.

Artifacter

This filter compresses the image as a JPEG with a very low quality. If you wish to adjust the quality you can set the property compressionQuality in Artifacter.java.

The command line argument for this filter is --artifacter.

RGB Shifter

This filter shifts the red, green, and blue values for the image by a random amount.

The command line argument for this filter is --rgb-shifter.

Before	After

Repeater

This filter repeats the image along the X and Y axis. To specify the number of repetitions, set the X_REPEAT and Y_REPEAT constants in Repeater.java

The command line argument for this filter is --repeater.

Before	After

RGB Shift Repeater

This filter combines the Repeater and RGB Shifter. As it repeats the image, it applies the RGB Shifter filter to it.

The command line argument for this filter is --rgb-shift-repeater.
