Hi,

Question,

How can I record with a keypress an another keypress to stop recording (the recording has to be a pdf or png but without the background).

This is what I already have.

float x,y,px,py;
                  float zachter = 0.01;

float diameter = 30;

                  int weight;

                  /**

                   * changing colors and size by moving the mouse

*

* MOUSE

                   * position x : size

* position y : color

*

                   * KEYS

                   * s : save png

                   * p : save pdf

                   */

                        import java.util.Calendar;

                        import processing.pdf.*;

boolean savePDF = false;

                        void setup(){

                          size(800,800);

                          smooth();

                          color(225,223);





                              }

                        void draw() {



                          float targetX = mouseX;

                              float targetY = mouseY;



                          float targerY = mouseY;

y = y + (targetY - y) * zachter;

                                x = x + (targetX - x) * zachter;

                                strokeWeight(weight);



                                line(x, y , px, py);



                                px=y;

                                py=x;

                               // end of pdf recording

                                if (savePDF) {

                                savePDF = false;

                                endRecord();

                                }

                              }

                                    void keyPressed() {

                                      if (key=='s' || key=='S') saveFrame(timestamp()+"_##.png");

                                      if (key=='p' || key=='P') savePDF = true;

                                          }



                                      String timestamp() {

                                      Calendar now = Calendar.getInstance();

                                      return String.format("%1$ty%1$tm%1$td_%1$tH%1$tM%1$tS", now);

                              }
