RasterImageManipulator is a free program for image processing and fractal exploration. It has many features for customizing the appearance of fractal images. These include special filters, a palette editor, gradient palette creator, and animated palette cycling.
Java™ 1.4 or higher is needed to run this program. A suitable Java™ Runtime Environment (JRE) can be downloaded from http://java.sun.com
The program is invoked with the following command:
java -jar rimanip-0.1.jar [file]
Main Window
Fractal Browser
- Navigation
- zoom in on fractal be selection of a rectangular region with the mouse
- back/forward buttons work like a web browser
- "stop" button allows interruption of the fractal iteration thread
- fractal locations can be saved as XML files
- Colors
- up to 65536 colors and/or iterations
- gradient palette creator
- create custom palettes
- save/load using standard rgb text files
- Images
- images of any size can be created (limited by the memory and speed of the computer)
- images can be saved in any format supported by the javax.imageio plugins (png format is recommended)
- Histograms
- fractal iterations
- used colors
Image Editor
- Filters
- blur
- color component rescaling
- conversion to/from indexed and rgb formats
- indexed images
- redistribute pixel indexes
- create gradient palette
- sort palette by hue
- Transforms
- rotation by arbitrary angles
- resize
- flip horizontally/vertically
- Histograms
- rgb luminescence
- indexed palette
Color Cycle Animation
- rate adjustable by frames per second orlatency
- reverse button
- adjustable step size
- note: if the animation does not appear to work, it is probably because the step size matches the palette size. Just change the step size to a smaller value.
Gradient Filled Shape
- infinitely scalable gradient fill
- same palette tools as Fractal Browser (above)
- 5 shapes are currently available, though any java.awt.Shape
could be used
- ellipse
- five pointed star
- rectangle
- heart
- daisy petal
