How to export PDF files in P3D mode ?

all

Hello,

I'm surprised not to find the answer on the forum : How to export PDF Files in P3D mode ? I don't have trouble in P2D. I use the PDF library without difficulty. But now, I need to do it in P3D, to get 2D PDF files... Thank you for your help. Best,

koogs

Use beginRaw with PDF. See reference.

BeginRecord moans about not being available using this renderer in 3d but beginRaw doesn't. I only found this out on Monday.

Hello koogs,

Thank you for your time. Unfornunately, it doesn't work. I tried with a easy example (from the Reference page) :

import processing.pdf.*;
Boolean saveOneFrame = false;

void setup() {
  size(400, 400, P3D);
}

void draw() {
  if (saveOneFrame == true) {
    beginRaw(PDF, "Export/Raw"+frameCount+".pdf");
  }

  line(pmouseX, pmouseY, mouseX, mouseY);

  if (saveOneFrame == true) {
    endRaw();
    saveOneFrame = false;
  }
}

void keyPressed() {
  if (key == 'r') saveOneFrame = true;
}

But I have only a white background ! I keep looking for... Best

Your sketch works for me, but if you don't move the mouse while pressing "r", then it will result in drawing only a point instead of a line, which might be hard to spot. Does it still appear empty if you draw a fixed line?

line(0, 0, width, height);

koogs

line(mouseX, mouseY, mouseX + 100, mouseY + 100);

it's exactly as benja says, you'll get a 0 length line if you aren't moving the mouse. the above replacement will fix it.

but you will only get at most 1 line in the pdf with that example, because you're only drawing one line between the start and end of recording.
