Hi

Is there an ETA on processing 2.0

Hi

When runing an exported applet / jar from the command line using

java -jar QubulusMaps.jar

it works just fine. This jar has all the dependencies merged into it and is the default export option.

However when choosing the option "Force 'Multiple-Jars' (for custom OpenGL renderers)" I get the following results.

C:\users\martin\workspace\QubulusMaps\applet>java -jar QubulusMaps.jar

Could not find the main class: qubulusmaps.QubulusMaps. Program will exit.

I tried the approach here http://processing.org/discourse/yabb2/YaBB.pl?num=1271480246 by calling

java -cp .\core.jar;. QubulusMaps

but get the following error

Could anyone tell me how to make the multi jar scenario run so it finds both PApplet and my main class?

Hi

Has anyone managed to use ProGuard on jar files exported by EclipseP5Exporter in Proclipsing?

Does anyone know?

Looking the the controlP5 homepage the image shows a horizontal layout. But the example code arranges them vertically. I can't figure out how to arrange them horizontally. Thanks.

Hi

Is there anyway to get a mouse over event for individual items in a ListBox?

I see the background color changing on mouse over so there must be some events. Are they accessible outside?

Hi all

I am having some problems with the GStreamer factory.

System:
- W7 x64,
- Eclipse x64,
- java 7 x64 u2,
- Procssing 1.5.1
- Using proclipse

Background:
After first installing GStreamer I had to fix libraries not being imported to eclipse properly. See problems and fixes below.

NoClassDefFoundError
https://forum.processing.org/topic/gsvideo-proclipsing-eclipse
(jna.jar was not imported properly by proclipse)

UnsatisfiedLinkError
https://forum.processing.org/topic/gsvideo-0-8-in-eclipse-unsatisfiedlinkerror-unable-to-load-library-gstreamer-0-10
(Moving gstreamer folder not imported properly by proclipse)

Current status:
Everything builds and runs now but I am experiencing other problems.

1. Can not start GStreamer factories
No such Gstreamer factory: xvidenc
No such Gstreamer factory: x264enc
No such Gstreamer factory: schroenc
No such Gstreamer factory: jp2kenc

Why is this? Are the codecs in some library that I am still missing?

2. MJPEG is the only one working on very short movies
I can only use MJPEG output without erros. However if I record more than 20+ seconds I can not play the video. The file grows to the correct size but I can't view it. Can I post it somewhere for you to have a look at it? My guess is that the container does not agree with MJPEG?

3. THEORA files are 0 bytes (less important but maybe a bug?)
When using THEORA the file is never larger than 4 bytes.

Hi

I have encountered two problems with the ContolP5.Range class.

First question is setLow/HighValue() vs setArrayValue()

1. //This works but yields to controller events
   
2. adlDateRange.setLowValue((float)animationRunnerStart);
3. adlDateRange.setHighValue((float)animationRunnerEnd);
4. 
   
5. //This does not seem work?
6. //Atleast it does not trigger a controller event. But if I click the bar it jumps to the udpated position.
7. adlDateRange.setArrayValue(new float[]{(float)animationRunnerStart,(float)animationRunnerEnd});  

Hi

I am trying to visualize GPS data on top of a map and I am having a hard time creating transparent images to use as layers.

DotLayer is not a PApplet but gets PApplet passed in constructor. To set things up I read GPS values from a csv file

1. public class DotLayer {
      
       PApplet parent;
       PGraphics pg;
       PImage im;
       CSVReader csvreader;
      
       int layerWidth;
       int layerHeight;
      
       float xy[][];
   
      
       DotLayer(PApplet parent, int layerWidth, int layerHeight) {
           this.parent = parent;
           this.layerWidth = layerWidth;
           this.layerHeight = layerHeight;
      
           pg = parent.createGraphics(layerWidth, layerHeight, PConstants.JAVA2D);
       }
   
       public void loadCSV(String csvfile) {   
           csvreader = new CSVReader(this.parent, csvfile); //CSVReader is Table class http://benfry.com/writing/archives/3
          
           createPoints();
       }
      
       private void createPoints()
       {
           im = parent.createImage(layerWidth, layerHeight, PConstants.ARGB);
   
           xy = new float[csvreader.getRowCount()-1][];
          
           for(int i=1;i<csvreader.getRowCount();i++){
              
               //Get long and lat and convert to floats.
               float lon = Float.parseFloat(csvreader.data[i][1])*0.000001f; //Parse and shift string
               float lat = Float.parseFloat(csvreader.data[i][2])*0.000001f;
              
               //Convert to screen coords
               xy[i-1] = map.getScreenPositionFromLocation(new Location(lat, lon)); //Unfoldingmaps
      
           }
   
           drawDots();
   
       }
   

In my first attempt I draw directly on the PImage. Then I tint(gray, alpha) the PImage which gives me ability to fade the dots in and out.

1. //    public void drawDots()
   //    {
   //        //Add dots to image
   //  
   //        for(int i=1;i<csvreader.getRowCount();i++){
   //            im.set((int)xy[i-1][0], (int)xy[i-1][1], ((PApplet)parent).color(r,g,b)); //Only a small pixel dot.
   //        }
   //    }
   //   
   //    public void draw() {
   //        pg.background(255,0);
   //       
   //        pg.beginDraw();
   //        pg.tint(255,a); //Working fine
   //        pg.image(im,0,0);
   //        pg.endDraw();
   //        parent.image(pg,0,0); //Give pg to parent
   //    }

Hi

Is it possible to connect to a mongo db from inside processing?

If not is there any way to mix java to get access to a mongo db?

Hi
I am trying to use Control P5 with a simple exampel I found at openprocessing. However I am not able to draw lines anymore if I choose to initiate ControlP5. If I comment out the ControlP5 everything works.

My guess is that controlP5 overdraws the canvas but I can't figure out how to synch them right.

main program - here controlSetup() is commented out and it is possible to draw on canvas. Try to commenting it in and the canvas becomes undrawable.

1. import controlP5.*;
   
   // Globals
   ControlP5 controlP5;
   ProceduralScribbler ps;
   public float rseed = 0.4; // seed value
   public float brushdist = 40.0; // brush distance sensitivity
   
   // Canvas
   int backgroundColor = 255;
   int strokeColor = 50;
   
   void setup(){
     size(900,600);
     background(backgroundColor);
     stroke(0, strokeColor);
     smooth();
     //controlSetup();
     ps = new ProceduralScribbler(0);
   }
   
   void draw(){
   
   }
   
   void mouseDragged(){
    
     ps.update(mouseX,mouseY);
   
   }
    
   void keyPressed(){
     if (key == ' ') {
       ps.reset();
     }
     if (key == 'm') {
       //controlP5.draw();
     } 
   }
   

scribble class

1. class ProceduralScribbler
   {
     ArrayList history = new ArrayList();
   
     int activeScribble = 0;
     public ProceduralScribbler(){}
    
     public ProceduralScribbler(int activeScribble)
     {
       activeScribble = activeScribble;
     }
   
     public void update(int mouse_x, int mouse_y)
     {
       switch(activeScribble)
       {
         case 0: // Sketchy
         {
           PVector d = new PVector(mouse_x,mouse_y,0);
           history.add(0,d);
           
           for (int p=0; p<history.size(); p++){
             PVector v = (PVector) history.get(p);
             float joinchance = p/history.size() + d.dist(v)/brushdist;
             if (joinchance < random(rseed)) 
             {
               line(d.x,d.y,v.x,v.y);
             }
           }
         }
         break;
         default: break;
       }
     }
    
     public void reset()
     {
       background(255);
       history.clear();
     }
   }
