Hi I am trying to create a very simple image thumbnailer in
JSP such as:
Get imageX.png
Reduce 65 pixels X 65 pixels
Output imageXthumb.png
I have read through a million different documents and have seen a million different ways to do this. I know that I need it to be able to read jpg, gif, and png files, which apparently means I need to user the javax.imageIO.* . I know most people would suggest doing this with a
servlet but my boss says I have to do it with JSP so if there is anyone out there who can direct to a good resource or who has some code I can look at I would really appreciate it.
I have checked:
http://java.sun.com/j2se/1.4.2/docs/guide/imageio/spec/imageio_guideTOC.fm.html I have tried to piece together a little JSP app from this info but I cant seem to get problems with the bufferedImage not being recognized in my netbeans. I then looked for other code online and found this which doesn't work either:
<%@ page import="java.io.*" %>
<%@ page import="java.io.File" %>
<%@ page import="java.util.*" %>
<%@ page import="java.util.Iterator" %>
<%@ page import="java.awt.image.*" %>
<%@ page import="javax.imageio.*" %>
<%@ page import="javax.imageio.IIOImage" %>
<%@ page import="javax.imageio.ImageIO" %>
<%@ page import="javax.imageio.ImageIO.*" %>
<%@ page import="javax.imageio.ImageIO.getReaderFormatNames"%>
<%@ page import="javax.imageio.ImageIO.getImageReadersBySuffix"%>
<%
ImageWriter writer;
BufferedImage im = new BufferedImage("/image.jpg");
int tw = im.getWidth() / 5;
int th = im.getHeight() / 5;
BufferedImage thumb = new BufferedImage(tw, th);
Graphics2D g2D = thumb.createGraphics();
g2D.drawImage(im, 0, 0, tw, th, null);
List thumbnails = new ArrayList(1);
thumbnails.add(thumb);
// IoImage holds image, thumbnail, metadata
IIOImage iioim = new IIOImage(im, thumbnails, null);
writer.write(iioim);
%>
If some one could please help me I would be extremely appreciative
