From inside my library, can I tell the sketch is rendering PDF?

in Library and Tool Development • 2 years ago

Some WordCram users want to render their WordCrams in PDFs, which doesn't work right now. I'm entertaining the idea, but I think I'll need substantially different WordCram "engines".

My question is, how can I tell that the sketch is rendering to PDF? I tried using {sketch}.g.getClass().getName(), which seems to be where Processing stores your choice of JAVA2D, P2D, P3D, PDF, etc. But there are different ways of rendering PDFs, and that technique doesn't always work.

It seems like Processing uses the processing.pdf.PGraphicsPDF renderer if the sketch looks like this:

size(400, 400,PDF, "test.pdf");

...stuff

exit();

But it uses the processing.core.PGraphicsJava2D renderer if the sketch looks like this:

size(400, 400);

beginRecord(PDF, "test.pdf");

...stuff

endRecord();

exit();

Internally, it actually creates a separate PGraphics for the PDF, which you can access through {sketch}.recorder, and check it's classname. That's what I'll be doing for now...
