headless rendering to a png file?

hydrodog

I can render to a pdf file with:

size(600,600,PDF);

is there any way to do the same for any kind of graphical file, like a .png?? I am trying to render on a headless machine.

headless machine is a different issue, you should search these words from the main site.

The only way I can figure to go headless is to select PDF rendering, then do an offscreen render to png. This is not ideal.

All we need is to attach a PGraphics to a PImage. Unfortunately, it appears the only supported way of doing this is the method createPGraphics() in the PApplet class. Creating a PApplet wants to open a window on the screen. So we select the renderer for PDF: size(1,1,PDF); This fails on Windows 64 with xception in thread "Animation Thread" java.lang.NoClassDefFoundError: com/lowagie/text/pdf/FontMapper
