I try to use Processing in eclipse and it works great without P2D, but when i use P2D, i can run as application, but when i export as runnable jar it didn't work (white screen) : it works when i have an application without P2D.

Any idea ?

Thanks you in advance

I made an application using face recognition with openCV( http://ubaa.net/shared/processing/opencv/) and processing 2.08.

When i export and run the application on mac or windows where opencv framework is installed everything is ok, but when i put the exported application on another computer, this didn't work : do you if it's a regular issue or if there is a solution to distribute the application with the opencv framework embedded in the app ?

Sorry for my bad english, and thank you in advance for the help !

I work on a processing project for an exhibition, and i work on the 2 version : do you think its better to work with the 1.5 for better stability for my exhibition ?

Thank you !

I'm just trying to use the resize function on a PImage, and it seems that this function don't work if you get greater parameter than the PImage original size (to get a larger image). I knon that i can do this by an another way, but i just want to know is this issue is "normal".

Here is my code, form the natives examples (the original size image " moonwalk.jpg" is 640x480).

2. /**
3.  * Load and Display 
4.  * 
5.  * Images can be loaded and displayed to the screen at their actual size
6.  * or any other size. 
7.  */
8.  
9. // The next line is needed if running in JavaScript Mode with Processing.js
10. /* @pjs preload="moonwalk.jpg"; */ 
11. 
    
12. PImage img;  // Declare variable "a" of type PImage
13. 
    
14. void setup() {
15.   size(800, 600);
16.   // The image file must be in the data folder of the current sketch 
17.   // to load successfully
18.   img = loadImage("moonwalk.jpg");  // Load the image into the program  
19.   img.resize(800,0);
20. }
21. 
    
22. void draw() {
23.   // Displays the image at its actual size at point (0,0)
24.   image(img, 0, 0);
25. }

Thanks for your help !

And happy new year :D

Edit : BTW this work on 1.5, but didn't on 2.0

Edit 2 : The issue is known : http://code.google.com/p/processing/issues/detail?id=1463, we have to wait for the new release :)

I'm new on processing, and i don't know wich processing version is better to start to learn now (i'm already used to programmation) : is it a loss of time to learn the 1.5.1 because the transition to 2.0 is on the way ? or is it better to start with the 1.5.1 because more stable, more documented, more library ?

Thanks for your help !

I'm really new in Processing, and used to work with AS3, but i'm really excited to play with Processing. I have a project for an art installation, that i first code in AS3, and i wanted to made this project in Processing to get better performance.

The first step of my project is just to play in fullscreen what the webcam see.

I tried this with the basic Capture function with the video lib, and i made an other version with openCV. I'm suprised that the performance i really bad : only 15 FPS with this 2 version. I noted, for the openCV version, that just the  opencv.capture (without feedback of the capture in fullscreen) slow down to 15 FPS.

I tried the same thing in AS3 with AIR, and i got 40+ FPS ... So i'm suprised of processing performance ...

Here is the code i used :

Video Lib Version :

1. import processing.video.*;
   
2. Capture cam;
3. void setup() {
4. size(displayWidth, displayHeight)
5.     cam = new Capture(this, 640,480);
6. cam.start();
7. }
8. }
9. 
   
10. void draw() {
11. if (cam.available() == true) {
12. cam.read();
13. }
14. image(cam, 0, 0, width, height);
15. text(int(frameRate),200,200)
16. 
    
17. }

Here is the OpenCV version

 
                   

                    
import hypermedia.video.*;
                    
OpenCV opencv;
                    
void setup() 
                    
{
                    
  size(displayWidth, displayHeight);
                    
 opencv = new OpenCV(this);
                    
 opencv.capture(640, 480);
                    
}
                    


                    


                    


                    
void draw() {
                    
 opencv.read();
                    
 image(opencv.image(), 0, 0, width, height);
                    
 text(int(frameRate),200,200); 
                    
}
                   

I'm on the last beta release of processing 2, m'y resolution is 1280x800, i'm on old macbook (2008) - OSX 10.6, and i use the isight integrated webcam.

Anybody can help me to get better performance ? Or do you think AS3 is much performant than Processing to do that ?

Thanks in advance for your help !
