This section illustrates you how to use Image I/O library.
The ImageIO class provides the method to read and write image. We are providing you an example which copies the specified input file into the output file. A file image4.jpg is defined as input file which is read by the method read() of ImageIO class and returns a buffered image after decoding the file.
A matrix is defined in the variable data of float type. This matrix is defined by the class Kernel to describe how a pixel affect its position in the output image of a filtering operation. The class ConvolveOp provides a correlation from the source to the destination. The method filter(input, output) of class ConvolveOp performs a translation on BufferedImages.
The method write(output, "GIF", outputFile) writes into the output file logo.gif.
Here is the code of CopyImage.java
When you run the above program, the input file is copied into the output file specified.
