In this example we are converting image of any format into jpg format.
Import java.io.* package and class javax.imageio.ImageIO and java.awt.BufferedImage. The package java.io.* is used for input and output operations through data streams, serialization and the file system. Classes ImageReader and ImagrWriter inherit the static methods from the class javax.imageio..ImageIO for reading and writing the images respectively. The class java.awt.BufferedImage extends Image class and implements WritableRenderedImage interface. The class BufferedImage is used to access an image.
The methods used in this example are:
write(RenderedImage im, String formatName, File output): This method is used to write an image. This method takes three parameters first one is Renderedimage, second is format in which the image is to be converted and last is name of the file on which the image is to be writen. The format name may be gif, jpg, png etc.
read(File input) : This is used to read an image.
This example reads the image name passed at the command prompt for
converting the image into the jpg format. In this example we are reading the image from system by
using read() method of ImageIO class. We
are using write() method for conversion of an image of any
format into the jpg format.
Here is the code of the program :
Input on DOS Prompts :
C:\image>java GIFToJPG Enter image name
rajeshxml2.gif Enter the output image name(.jpg):
raju.jpg Your image has been converted successfully
Output of The Example:raju.jpg
