public class ImageOps

extends Object

ImageOps is a class that allows basic opearations on images from the Command Line. Below is a table of the currently supported operations and their syntax

Supported Operations
Operation	Syntax	Comments
Add two images	-add <image1> <image2> <output file>	* Note: Some image types are incompatible for these operations (in any order). GrayImage&ColorImage (or RealColorImage) ComplexImage&ColorImage (or RealColorImage) RealGrayImage&ColorImage (or RealColorImage)
Subtract two images	-subtract <image1> <image2> <output file>
Multiply two images	-multiply <image1> <image2> <output file>
Divide two images	-divide <image1> <image2> <output file>
Add a constant to all the pixels in an image	-addconst <image1> <const>+ <output file>	* Note: It is not possible to use these operations using float or double values on eithier a GrayImage or a ColorImage. * Note: ColorImages and RealColorImages require 3 constants, one for each plane. Complex Images require two, one for the real plane and one for the imaginary plane.
Subtract a constant from all the pixels in an image	-subtractconst <image1> <const>+ <output file>
Multiply a constant by all the pixels in an image	-multiplyconst <image1> <const>+ <output file>
Divide all the pixels in an image by a constant	-divideconst <image1> <const>+ <output file>
Clip an arbitary region of an image	-clip <image1> <const1> <const2> <output file>	const1 is the low value const2 is the high value
Clear an image to a value	-clear <image1> <const> <output file>	the constant is the value to set it to
ByteSize operation	-bytesize <image1> <output file>
Diff operation	-diff <image1> <image2> <output file>

* ImageOps also support a "-debug" option. This will display some helpful imformation in debugging problems you might encounter.

Examples of a Command-lines:

java ImageOpps -add C:\pictures\test1.ppm C:\pictures\test2.ppm C:\Output\out_test.ppm

java ImageOpps -mulitiplyconst C:\pictures\test1.ppm 5 C:\Output\out_test.ppm -debug

java ImageOpps -clip C:\pictures\test1.ppm 40 150 C:\Output\out_test.ppm
