Jpeg Load and Modification

[fpgiv]

Hi,
I'm trying to load a jpeg image from a file, add some text to the image, and then save it through Java--again as a jpeg. I don't need to see the image anytime during this process. I've been searching online all day, and I can't find anything. Can anyone point me in the right direction?
Thanks!

Use the ImageIO class to read and write the image, and use the Graphics object obtainable from the BufferedImage ( obtained from ImageIO.read() ) to draw you desired text/graphics.

OK, I got it to read in no problem, but I just realized that I do need to see the image that I am reading--so I can check on the modifications I've made to see if they are what I wanted to do. So, how would I either view the image once I read it, or print it to a file so I can see it?
Thanks,

How much swing/awt do you know ?
To display an image on screen, you need to use the Graphics2D.drawImage() method.

Not that much. However, what I am doing is just viewing the file in my file system after I make a change and write it to a file. This seems to work.

What I am working on now is trying to expand the area I have to work with once I read in the image. Once I read in the image, I want to add a blank area beside the original image where I can add more text, etc. Is there a simple way to do that?

Yes, as I said in my first reply, obtain a Graphics object from your BufferedImage, and then utilise the methods in that object.

Sounds like you need to learn Swing if you want to do this in an "interactive" application.
