A few days ago I asked a question about creating PDFs without recording them ( http://forum.processing.org/topic/problem-creating-with-pdfs-behind-the-scenes )

Thanks to someone here, that problem was solved but I can't quite figure out how to create a PDF of a particular size, manipulate it, and then save it again.

What I can do is this :

1. PGraphicsPDF pdf;
2. pdf = (PGraphicsPDF)beginRaw(PDF, "find.pdf");
3. pdf.beginDraw();
4. // do some stuff with pdf as the graphics canvas
5. pdf.endDraw();
6. endRaw();

This works to create a pdf, draw on it and save it to disk. But using beginRaw this way doesn't allow me to set the size / resolution of the pdf file.

Alternatively I can do this :

1. PGraphicsPDF pdf;
2. pdf = (PGraphicsPDF)createGraphics(paper_x, paper_y, PDF, "find.pdf");
3. pdf.beginDraw();
4. // do some stuff with pdf as the graphics canvas
5. pdf.endDraw();

Which would seem to let me define the width and height of the pdf file. But I can't find any example online of then saving the pdf into a file. In every pdf file writing example I've discovered, writing to file just seems to happen at endRaw()

But there must be another way of achieving this if you aren't using the beginRaw / endRaw methods.

Update :

I should mention. If I just try to do a

pdf.save("fileName.pdf");

after the pdf.endDraw() I get the following exception :

1. java.lang.RuntimeException: No save() for PGraphicsPDF
2.     at processing.pdf.PGraphicsPDF.nope(Unknown Source)
3.     at processing.pdf.PGraphicsPDF.save(Unknown Source)

 
Clearly, something in Processing's PDF library knows how to write a PDF file. But it seems that that knowledge hasn't been incorporated into the PGraphicsPDF class.
