Re : PDF export / preserving ability to edit text

It works for me in Processing 1.5.1 and 2.0b7 on WinXP. The problem may be your font.

I can select the text in Adobe Reader and also edit it in Adobe Illustrator CS6.

Adapted Code

1. import processing.pdf.*;
2.  
3. void setup() {
4.   size(200, 200, PDF, "output.pdf");
5.   textMode(MODEL);
6.   background(100);
7.   textFont(createFont("Arial", 30), 30);
8. }
9.  
10. void draw() {
11.   fill(0);
12.   text("Hello", 30, 60);
13.   exit();
14. }
