Hi. I'm having problems with this code from the PDF reference:

Code:

import processing.pdf.*;

PGraphicsPDF pdf = createGraphics(300, 300, PDF, "output.pdf");
pdf.background(128, 0, 0);
pdf.line(50, 50, 250, 250);
pdf.dispose(); 

I suppose I could poke my nose into what’s going on under the hood, but I'm a) feeling a little lazy today, and b) sort of tight on how much time I can take out on this.

Following Marius Watz' export example, I tried to force it's hand with this addition:

Code:

PGraphicsPDF pdf = (PGraphicsPDF)createGraphics(300, 300, PDF, "output.pdf"); 

Which makes it happier, since it gives me back an instantiated object, but then I get a nullpointer exception on the pdf.background() method and all other methods (even pdf.line()).

beginExport() works fine, but I want to export directly to PDF, no writing to the screen, which the above method is supposed to cover.

Any ideas?

I tried various arrangements of the commands. This was the first I managed to get to work:
Code:

import processing.pdf.*;
PGraphicsPDF pdf;

void setup(){
  size(200,200,P3D);
  pdf = (PGraphicsPDF)createGraphics(300, 300, PDF, "output.pdf");
  beginRaw(pdf);
  pdf.fill(255);
  pdf.stroke(10);
  pdf.line(0,0,200,200);
  endRaw();
}
 

It didn't like actions being performed on "pdf" before beginRaw(pdf) and it doesn't like not using P3D either. It does however not draw to the screen and create a pdf separate from the stage.

Great. Works on my end. That sure was fast. I should have waited. Now I have to remove all that work-around code
