My project structure:

Well, I load the Images from my Background.java with PApplet.loadImage("img/galaxy.gif") for example. It works in eclipse, but if I try it to export them to a JAR file and run it after, it gives me some exceptions:

java.lang.NullPointerException at processing.core.PApplet.dataFile(PApplet.java:8016) at processing.core.PApplet.dataPath(PApplet.java:7993) at processing.core.PApplet.createInputRaw(PApplet.java:7093) at processing.core.PApplet.createInput(PApplet.java:7011) at processing.core.PApplet.loadBytes(PApplet.java:7301) at processing.core.PApplet.loadImage(PApplet.java:5439) at processing.core.PApplet.loadImage(PApplet.java:5363) at make.object.Background.setup(Background.java:47) at make.Applet.setup(Applet.java:16) at processing.core.PApplet.handleDraw(PApplet.java:2412) at processing.awt.PSurfaceAWT$12.callDraw(PSurfaceAWT.java:1557) at processing.core.PSurfaceNone$AnimationThread.run(PSurfaceNone.java:316)

Well, this line here: at make.object.Background.setup(Background.java:47)

It tells me it can't find any images. I had check my JAR file and the structure looks okey. I have my img folder here, my make folder (with the other stuff inside) and the imported core library. But why it doesn't load my images now?

Sorry for my bad english. I hope you understand my problem. ^^

class PWindow extends PApplet { // PImage[] subs = new PImage[2]; // String testKey="m"; PWindow() { super(); PApplet.runSketch(new String[] {this.getClass().getSimpleName()}, this);
}

void settings() { size(1920, 1080); }

void setup() { background(150); // subs[0]=loadImage("test.png"); }

void draw() { //if (keyPressed && key == testKey.charAt(0)){ // image(subs[0], 0,0); println("well it works"); //} }

void mousePressed() { println("mousePressed in secondary window"); } }

How can i put a image in a public class extend PApplet (extra window) I can not figure out how i should do that

Greetings

I'm playing with the 3.0a versions and have been using 5 for a while and upgraded to 9 after a format. I see quite a lot has changed (awesome!), but am finding some things not working. I hope I did enough research before posting here.

I'm using 'sketchPath' to determine the path of the sketch to open some files in my data folder
String UBUPFile = sketchPath + "/data/UBUP.bin";
Where this has been working fine up until 3.0a5, in a9 it produces the following error
The field PApplet.sketchPath is not visible
There doesn't seem to be anything in the revisions.txt, unless I missed something

Tab 1:

void setup() {
  size(500, 500);

  String[] args = {"TwoFrameTest"};
  SecondApplet sa = new SecondApplet();
  PApplet.runSketch(args, sa);

  ThirdApplet ta = new ThirdApplet();
  PApplet.runSketch(args, ta);
}

void draw() {
  background(0);
  ellipse(50, 50, 10, 10);
}    

Tab 2:

public class SecondApplet extends PApplet {

  public void settings() {
    size(300, 300);
  }
  public void draw() {
    background(255);
    fill(0);
    ellipse(100, 50, 10, 10);
  }
}

public class ThirdApplet extends PApplet {

  public void settings() {
    size(400, 400);
  }
  public void draw() {
    background(255);
    fill(0);
    ellipse(100, 50, 10, 10);
  }
}

There is an issue however; when I run the code, the original window is displayed as its default size, even if a size method with different values is called. Strangely this even seems to happen if the other windows aren't called; the code in the second tab just has to be in the sketch folder and doesn't have to be referenced in any way. Does anybody have any idea what is happening and how I might fix it?

To reproduce the issue run the code from the bottom. Conversion will start an you will get pngs like this:

if you do a mouse click on the canvas, the size of the pngs that should be generated is changed and a few new items are added. The results look like in the screenshot below, some of the images are blank, some are distorted and they still have the old size.

Is there a way to avoid this behavior? is this a bug in processing? am i missing something?

Any input appreciated!

PGraphics png;
ArrayList<String> cue = new ArrayList<String>();
boolean conversion = false;
int pngSize = 64;

void setup() {
  size(400, 400);
  println("creating 64px letters");
  cue.add("A");
  cue.add("B");
  cue.add("C");
  conversion = true;
}

public void mousePressed(){
  println("creating 128px letters");
  pngSize = 128;
  cue.add("A");
  cue.add("B");
  cue.add("C");
  cue.add("D");
  cue.add("E");
  cue.add("F");
  conversion = true;
}

void saveNextInCue(){
  String letter = cue.remove(0);
  println("pngSize value is "+pngSize);
  png = createGraphics( pngSize, pngSize);
  png.beginDraw();
  png.textSize(30);
  png.text(letter,30,30);
  png.fill(random(255),0,255);
  png.rect(0,0,10,10);
  png.endDraw();
  png.save(sketchPath(letter+".png"));
}

void draw() {
  int bg = color(255,0,0);
  if (!conversion){
    bg = color(0,255,0);
  }
  background(bg);
  if( conversion == true){
    saveNextInCue();
    if(cue.size() == 0){
      conversion = false;
    }
  }
}

In main project file:

Map map;

void setup(){
...
map = new Map();
...
}

In Map's constructor, where (members) pgMap is a PGraphic and imgMap is a PImage, I create a graphic draw some stuff on it, save it out then reload it as an image:

...
//save to file
pgMap.save("map.png");

//re-load as an image
imgMap = loadImage("map.png");
...
}

Another of Map's methods:

void renderWorld() {
    image(imgMap, 0, 0);
}

If I call map.renderWorld() from draw() I get a null pointer/"map.png" not found error and sure enough map.png hasn't been created. If I comment out the single line in renderWorld() the map gets created normally and the program functions as expected!

I suspected a path issue but I've tried no path (as above), using a relative path to ./data and using an explicit path to /data but none of those work. A separate image used by the program stored in ./data loads from setup() without any path being specified:

loadImage("compass.jpeg");

I've also tried loading Map's image from setup(), rather than within the constructor like so:

map.imgMap = loadImage("map.png");

but that doesn't work either (also tried specifiying paths at that point).

This is on Linux Mint 32 bit with Processing 3.0.2, any help appreciated!

Thank you

launch (sketchPath("programa/test.exe"));

This code works on mac

launch (sketchPath("programa/test.app"));

myapp.exe

programa (directory)

-->test.exe

What is the correct path n windows for launch a external app from my aplication?

i don't know how to add video or image like in code? error: Could not load movie file video1.mov

Followed the recommendation to load the native library: https://www.chilkatsoft.com/java-loadLibrary-MacOSX.asp

and have been unsuccessful. The following provides the sketch and the errors from a debug execution,

Note: the .jar files in the "code" folder support the wrapper class in the sketch and are used to see if an instrument is attached... can't get to that point until I can load the libNatUSB.jnilib

In case you can't read the error message on the screen shot : "Native code library failed to load- try again?. java.lang.UnsatisfiedLinkError: /Users/westgallery/Desktop/Processing3testing/OmniDriverTests/code/libNatUSB.jnilib: dlopen(/Users/westgallery/Desktop/Processing3testing/OmniDriverTests/code/libNatUSB.jnilib, 1): no suitable image found. Did find: /Users/westgallery/Desktop/Processing3testing/OmniDriverTests/code/libNatUSB.jnilib: no matching architecture in universal wrapper Could not run the sketch (Target VM failed to initialize). For more information, read revisions.txt and Help → Troubleshooting."

Read the revisions and the Help... still stuck!

Any suggestions would be greatly appreciated.

error "The function saveTable(Table, String) does not exist"

saveTable() definitely exists in Processing Reference guide, and I think I've used the arguments right, so why am I getting this error?

Thanks!
