See File.renameTo()

He Philho,

It's me the student with his slideshow and taking pictures program again :) haha yeah Again!!

I looked at renameTo and it's also allready in the script. But a few things I can't do are things like.

- Counting number of files in a folder
- Moving them all at one time.
- Or move the oldest picture by date.

Can you or someone help me with that.

1. import hypermedia.video.*;
   import java.awt.Rectangle;
   
   OpenCV opencv;
   boolean pictureJustTaken = false;
   int startTimer;
   int interval = 5; // interval in seconds
   String path = "/Users/menno/Documents/Processing/picture_pool/";
   
   void setup() {
     size(320,240);
     opencv = new OpenCV(this);
     opencv.capture(width,height);
     opencv.cascade(OpenCV.CASCADE_FRONTALFACE_ALT);
   }
   
   void draw() {
     opencv.read();
     image(opencv.image(),0,0);
   
      Rectangle[] faces = opencv.detect(1.2,2,OpenCV.HAAR_DO_CANNY_PRUNING,40,40);
   
   
   
     if (pictureJustTaken == false && faces.length >= 1) {
       String fileName = "faces" + year() + "-" + month() + "-"  + day() + " "  + hour() + "."  + minute() + "."  + second() + ".jpg";
       File ff = new File(path + "_" + fileName);
       save(ff.getAbsolutePath()); // Long operation
       // Rename on the fly
       ff.renameTo(new File(path + fileName));
       pictureJustTaken = true;
       startTimer = millis();
       println(frame);
     } 
   
     if (pictureJustTaken) {
       if (millis() - startTimer > (interval * 1000)) {pictureJustTaken = false;}
     }
   }
   
   public void stop() {
     opencv.stop();
     super.stop();
   }
    
   
   

To count the number of files in a folder use File.listFiles

beware that renameTo() isn't guaranteed to work, especially if you're trying to write to an nfs mounted directory (have just been hit by this problem at work) so be sure to check the return value

He Guys,

Thanks for your reactions. But let me tell you something about my background :) In short: I'm a designer and not a programmer. I made and installations and found out the memory is piling up when it takes to much photo's.

The code above works fine but can you help me putting your suggestions in the code. I really don't know how to implement your suggestions

Hope you can help me.

Thanks so far
