How to decrease the size of image using a java peogram
Hi All,
I want to decrease the size of an image from MB to KB. I have some images of size around 1MB to 3MB. While displaying all those images in the browser it is taking so much time to download all those and display. So I want to write a Java program to make a duplicate copies of those images, which are small in height and width and display those images in small size. Basically I need to display all the list of images as thumbnail view or list view with faster speed.
Thanks in advance..

Yes BufferedImage sounds like what you want.
You could (1) Read the image (2) Obtain its dimensions and create a blank
scaled image (3) Draw a scaled version of the original image using the
Graphics2D obtained from the smaller one. (4) Save the smaller image.
The javax.util.ImageIO class will help with reading and writing the data and
Sun's Tutorial has a section on "2D Graphics".

The java.awt.Image class has getScaledInstance() method.
I thought it was what you want.

Thanks for the explanation pbrockway2 ..
but I am not able to create an object for the BufferedImage class. There is no constructor for that which reads the path of the original Image. I guess that there is some other option. I want some sample code for this. I will be very much thanksful to you if you give me that...
Thanks in advance..
