Re: not quite struts: handling Images

[Mark Lowe]

Not sure about the resize and save (3-4) but the rest i use for 
ensuring users dont upload any old sizes..

java.io.ByteArrayInputStream;
java.awt.image.BufferedImage;
javax.imageio.ImageIO;
byte[] image = form.getImage().getFileData();
ByteArrayInputStream  stream = new ByteArrayInputStream(image);
BufferedImage img = ImageIO.read(stream);
BufferedImage has getWidth and getHeight
Perhaps also better not to use getFileData on the formFile, and use the 
getInputStream method instead as its less heavy..

Hi -
after spending much time wondring through the JAI API I thought maybe 
one of you guys can help me:
I need a very simple:
1. upload-image (jpg/gif)
2. getProps (size, width)
3. resize
4. save JPG with custom compression.
The upload is done via FormFile, so I have the InputStream - all the 
rest via Java API - and I have no clue of where to get started :-(
Cheers,
Ron
