I've written a sketch (with some help) that can run on a folder full of SVG, manipulate them and then produce gif files of the manipulations. The only problem I'm having appears to lie with Geomerative. It appears to try to load the next file but doesn't display it on screen. Is there a way to unload one file in order to load another? Code is below. It requires Geomerative and GifAnimation

1. import gifAnimation.*;
   import geomerative.*;
   
   RShape shp ;
   RShape polyshp;
   
   int filecount = 0;  //for number of files
   int filecounter = 0; //to read through the next file
   
   String[] svgfile;   //for array of files
   String directory;   //directory of files
   
   String filename;
   
   float svgborder=20;
   float svgaspect, svgwidth, svgheight;
   
   GifMaker gifExport;
   
   void setup() {
     size(500,500);
    
     directory = selectFolder();
     println(directory); 
     File dir = new File(directory);
     svgfile = dir.list();
     println(svgfile);
   
   if (svgfile == null) {
     println("Folder does not exist");
    
   }
   else {
    
       //count how many files there are
       filecount = svgfile.length;
      
       //get the filename and full path of first svg file in directory
       filename = directory + '\\' + svgfile[0];
        
       RG.init(this);
      
       //load first shape
        shp = RG.loadShape(filename);
        shp = RG.centerIn(shp, g, svgborder);
        shp.translate(width/2, height/2);
       
       //create first gif file
        gifExport = new GifMaker(this, svgfile[filecounter]+"_destroyed"+".gif");
        gifExport.setRepeat(0); // make it an "endless" animation
        gifExport.setTransparent(28, 255, 26); // greenscreen effect
        
       //set pointer to next svg file
        filecounter++;
     } 
   }
   
   
   void draw() {
     // Green screen
     background(28, 255, 26);
   
     // We decided the separation between the polygon points dependent of the mouseX
     float pointSeparation = map(constrain(frameCount+175, 175, width-175), 175, width-175, 5, 275);
   
     // We create the polygonized version
     RG.setPolygonizer(RG.UNIFORMLENGTH);
     RG.setPolygonizerLength(pointSeparation);
   
     polyshp = RG.polygonize(shp);
     RG.shape(polyshp);
   
     // sometimes the first frame from the previous gif is displayed
     // so offset recording by 2 frames
     if (frameCount > 2) {
       gifExport.setDelay(1);
       gifExport.addFrame();
     }
   
     //after 92 frames get next file if there is one
     if (frameCount == 20 && filecounter < filecount) {
       filename = directory + '\\' + svgfile[filecounter];
       println(filename);
      
       //load new shape into screen this is the bit I cant get working
       shp = RG.loadShape(filename);
       shp = RG.centerIn(shp, g, svgborder);
       shp.translate(width/2, height/2);
      
       //polyshp = RG.polygonize(shp);
       RG.shape(polyshp);
      
       //close last gif file
       gifExport.finish();
      
       //open up next gif file
       gifExport = new GifMaker(this, svgfile[filecounter]+"_destroyed"+".gif");
       gifExport.setRepeat(0); // make it an "endless" animation
       gifExport.setTransparent(28, 255, 26); // greenscreen effect
      
       //reset framecount
       frameCount=0;
       //move pointer to next svg file
       filecounter++;
     }
     else {
       println("Files Processed");
     }
   
     println(frameCount);
   }
   

I wan to run this code on a folder containing around 1000 files (requires geomerative)

1. import processing.opengl.*;
   import processing.xml.*;
   import geomerative.*;
   import java.io.*;
   
   RShape shp;
   RShape polyshp;
   
   String svgfile;
   
   float svgborder=20;
   float svgaspect,svgwidth,svgheight;
   
   void setup() {
     size(600, 600, P3D);
     colorMode(RGB, 255);
     frameRate(1000);
   
     // VERY IMPORTANT: Allways initialize the library before using it
     RG.init(this);
   
     svgfile = selectInput();
   
     if (svgfile != null)
     {
       shp = RG.loadShape(svgfile);
   
       shp = RG.centerIn(shp, g, svgborder);
       shp.translate(width/2, height/2);
     }
   }
   
   //code to generate transparent image
   void greenScreen() {
     PGraphics frameToSave = createGraphics(width, height, P2D);
     frameToSave.beginDraw();
     loadPixels();
     frameToSave.loadPixels();
     float r,g,b;
     for (int i=0; i<pixels.length; i++) {
       r=red(pixels[i]);
       g=green(pixels[i]);
       b=blue(pixels[i]);
       if (r == 28 && g == 255 && b == 26) frameToSave.pixels[i]=color(r,g,b,0);
       else frameToSave.pixels[i]=color(r,g,b,255);
     }
   
     frameToSave.updatePixels();
     frameToSave.endDraw();
   
     int a = frameCount;
   
     frameToSave.save(svgfile+nf(a,5)+".png");
   }
   
   void draw() {
     background(28,255,26);
   
     // We decided the separation between the polygon points dependent of the mouseX
     float pointSeparation = map(constrain(frameCount+100, 100, width-100), 100, width-100, 5, 200);
   
     // We create the polygonized version
     RG.setPolygonizer(RG.UNIFORMLENGTH);
     RG.setPolygonizerLength(pointSeparation);
   
     polyshp = RG.polygonize(shp);
     RG.shape(polyshp);
   
     greenScreen();

Currently I'm having to open each file individually and then decide whtn to stop it but I'd like the script to run and then select a new file after 20 seconds or so. The files currently have random names.

I'm familiar with how to do this in bash (for file in *.svg do...) but can something similar be accomplished in Processing?

I'm trying to create a Processing sketch that can read the text from a file (preferably a .txt file) and then randomise the order of the sentences. So far I've succeeded in loading the text into an array but I've not found a way to recognise sentences instead. Can anyone advise how you'd do this?

I eventually want it to be able to recognise paragraphs and such, but baby steps ;-)

I'm trying to create a random date generator (borrowed some code from here) that generates dates in the future but I'm encountering a few problems. With my current code (below) the random dates sometimes are in the past or have the value "00". IS there a way to get around this, perhaps with using day() seconds() etc?

1. PFont reloj;
   
   int h; // hour
   int m; // minute
   int s; // second
   
   int d; // day
   int mo; // month
   int y; // year
   
   int lastsecond = 0;
   
   void setup() {
     frameRate(60);
     reloj = loadFont("Commodore_64_Angled-48.vlw");
     size(700,100);
     loop();
     textFont (reloj);
   }
   
   void draw() {
     h = int(random(24));
     m = int(random(60));
     s = int(random(60));
   
     d = int(random(31));
     mo = int(random(12));
     y = int(year()+random(2));
   
     if (lastsecond != s) {
       background(0);
       String y2 = nf(y,2);
       String y3 = y2.substring(2,4);
       String date = nf(h,2)+":"+nf(m,2)+":"+nf(s,2)+" "+nf(d,2)+"/"+nf(mo,2)+"/"+y3;
       println (date);
   
       // print text on screen
       fill(114,234,183);
       text(date,23,60);
       filter(DILATE);
       filter(BLUR,8);
       fill(176,242,215);
       text(date,20,60);
       filter(BLUR,1);
   
       // horizontal lines
       for (int y = 0; y <= height; y+= 5) {
         strokeWeight(0.1);
         stroke(20,200,20,20);
         line (0, y, width, y);
       }
       saveFrame("fecha-####.png");
     }
     lastsecond = s;
     fill(0,random(0,3));
     rect(0,0,width,height);
   
     //To select a date
     if((keyCode == ENTER)) {
       noLoop();
     }
   }
   
   

I'm loading an svg (though could be an image) into processing and centering it onto the screen (600x600). As I've made my graphic small enough to fit the screen I have no problems but eventually I want to be able to load any svg of any size and have it automatically fit to the size of the screen (proportionally), probably with a bit of a border. Is there any way to do this? I've tried scale() but it doesn't seem to have an option to scale to screen size

I'm trying to accomplish something like this but in Processing http://www.dinkypage.com/76566 I know that Processing is able to use PShape to load an SVG but are there any specific functions to modify the nodes and node handles?
