converting a "Graphics" object to a "BufferedImage"

[Arun Laksh]

Hi,

I have an object of class
java.awt.Graphics
or
java.awt.Component

I need to convert the drawing in this object to an object of type "BufferedImage".

Any suggestions on how this can be done?

Below is a more detailed description of the context of the problem.

Thanks.
-Arun.


I've been using this JGraph library to draw graphs.

Ultimately I would like my drawing to be a BufferedImage object.

The JGraph library uses a JGraph object to make all the drawings.

I can do getGraphics() on that to obtain an object of Class "Graphics"
(java.awt.Graphics) from the JGraph object.

Now, I'm lookin to this to a BufferedImage object.

first create BufferedImage then get Graphics from BufferedImage then paint
your component to this Graphics

how to turn get a Panel's Graphics into a BufferedImage

What you've said is true but I think the original poster may be looking
for something more like this

GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
GraphicsDevice gs = ge.getDefaultScreenDevice();
GraphicsConfiguration gc = gs.getDefaultConfiguration();

dbImage = gc.createCompatibleImage(pWidth, pHeight, Transparency.TRANSLUCENT);

This code works well if your in writing it from inside a Class that extends
JPanel, allowing you to get the Graphics of that specific panel into a BufferedImage
