pfd export a specific area / box

in Core Library Questions • 9 months ago

hello everyone. I'm a beginner at processing, so I'm pretty sure my question can be answered pretty quickly :)
so, i trying to figure out this task:

in my program there should be a box or area ( let's take for example a rect 500 x 500 px) and my control-field on the left side of the program via controlP5.

if i press the button "save", there should be 1 pdf generated, with all the information from / inside of this 500 x500 px box, without the control filed.

how can this be acchived?
thanks for any help!

It doesn't work like this: to make a PDF file, you must first tell to record the drawing, then to draw. No magical "save" button...

Hi, since controlP5 is by default drawn after processing has finished its own drawing routine, the following example shows you how to save a pdf without controlP5 elements.

import controlP5.*;
import processing.pdf.*;
// using controlP5 version 2.0.4 with processing 2.0b7
ControlP5 cp5;
boolean record;
void setup() {
size(800,600);
cp5 = new ControlP5( this );
Bang b = cp5.addBang( "save" )
.setPosition( 20 , 20 )
.setSize( 100 , 100 )
;
b.getCaptionLabel()
.align( CENTER , CENTER )
;
}
void draw() {
background( 230 );
pushMatrix();
if( record ) {
beginRecord( PDF , "grid-" + frameCount + ".pdf" );
}
fill( 0 );
translate( 200 , 50 );
for( int i = 0 ; i < 250 ; i++ ) {
float f = sin( ( frameCount + i ) * 0.01 );
pushMatrix();
translate( ( i * 50 ) % 500 , ( i / 10 ) * 20 );
rotate(f);
rect( 0 , 0 , 50 , 2 );
popMatrix();
}
if( record ) {
record = false;
endRecord();
}
popMatrix();
}
void save() {
record = true;
}

hey andreas! thanks for your reply, it's almost the thing i want! but, is it possible just to get the maxtrix grid as a pdf, without the space (where actually controlP5 was)? one way would be 2 windows, 1 for controlls and 1 for the matrix, but this solution would be windowed only right? the goal would be a fullscreen app
