No get() for PGraphicsPDF
May 22nd, 2009, 12:49pm  
Hi,

The sketch works fine using P2D or Java2D renderer, but when I try to write to
Code:
PDF (size(x, y, PDF, "filename.pdf")
;
I get "No get() for PGraphicsPDF" error.
The sketch uses the PApplet's get() function, but it is always trying to find the PGraphicsPDF's get() function - even if I specify Code:
super.get(x,y)
- , which I've seen it isn't implemented, so how can I solve this?

Thanks

Well, looks clear enough: get() isn't available for this PGraphics mode, probably because it is a vector format, with no pixels to get() from.
You might have to change your algorithm, or perhaps do a double rendering, on another 2D PGraphics, to get() from there and use the result on the PDF one.

Thanks PhiLho, that confirms my worst guess... so PGraphicsPDF is a vector format... but then which is the right way to render hires images (raster) bigger than screen size/resolution? Using double rendering mode (let's say P2D) and PDF(with   Code:
beginRecord()
and Code:
endRecord()
), am I forced to use the size specified in Code:
size(x,y)
?? or not?

Barring memory issues, you can (should) create a PGraphics of wanted size (no need to display) is where you do all your drawings. You can save it later.

Thanks a lot PhiLho, so this is the right way to render to disk!
Code:
PGraphics pg;

void setup() {
  size(100, 100);
  pg = createGraphics(high-x, high-y, P3D);
}


Unluckily, I'm having java.lang.OutOfMemoryError: Java heap space error at 2000 x 2000 pixel image Sad
so, maybe should I crop the the PGraphic and save them individually... I'm into mosaics now...

thks

If you go in the PDE to File > Preferences, you can assign more memory to Processing.
Beside, there are several threads in the forum on making big images, maybe they can be of help.

That's great PhiLho, ! I didn't read anything about this setting yet; Things go smooth now, so thank you very much!
