Export JFrame contents without making the JFrame visible

The attached (working) program creates a JFrame, adds a custom JPanel, draws some basic Graphics2D shapes, and finally exports the contents to a png file.

I need to be able to run the attached program without the JFrame actually showing up on my screen. Eventually, it will be run from the command line, and all I want is the exported file.  I tried to comment out the f.setVisible(true) line, but this causes an error.

Can this be done?

All you need to do is ignore the gui and work directly on the BufferedImage and save it as i showed

It seems that the whole approach so far is to use GUI components. I am having trouble stripping out the GUI and still making the png image. Am I not to use JFrame and JPanels? If not, what am I to draw on?

Ok. I understand now. I got it to work. It actually made my code a lot simpler getting rid of the unneeded GUI components. Thanks for your help. My java skills sure are rusty...
