If you expect help with this then you need to provide more information.

Did you create the sketch in Java mode?

Are you using any contributed libraries (what import statements do you have)?

When attempting to display in browser were you using JavaScript mode?

What were you using to export the applet?

GoToLoop

Processing 2+ doesn't export as applet anymore!
For that you either use Processing 1.5.1 or use an existing utility which accomplishes that!

quark

For Java mode sketches using the default (Java2D) renderer there is the Applet Exporter and Signer tool which works with Processing 2.1

jitesh_bhatti

yes m using export in java mode with processing 2.0 with applet signer and export tool

jitesh_bhatti

i have following import statements processing.papplet; processing.pimage;

quark

Are you using the P2D or P3D renderer?

If you are working in Processing IDE then the import statements are not required unless you have created your own class in a .java tab, try running your sketch without them.

m using processing IDE all other apps are running in browser but following code doesnt run in browser nor show any error

String iName="image.jpg";

void setup() {
  llegeixImatge("./"+iName);
  size(465, 600);
}

// parameters
// NO real control, so be careful

int NP=6000; // 1000 for line art, 10000 for complex images, O(N^2) so be patient!!!
int B=1; // try 2 or 3
float THR=28; // range 5-50
float MD=6; // range 0-10
int NMP=6; // range 1-15

float[][] punts;
color[] cpunts;
int [] usat;
int [] NmP=new int[NMP];
float [] NdmP=new float[NMP];

int inici=0;

PImage img;

void llegeixImatge(String s) {
  img = loadImage(s);
  img.loadPixels();
}

float fVar(int x, int y) {
  // neighborhood 2B+1x2B+1 pixels
  float m=0;
  for (int k1=-B; k1<=B; k1++) {
    for (int k2=-B; k2<=B; k2++) {
      color c=img.pixels[(y+k1)*img.width+(x+k2)];
      m+=brightness(c);

the problem was due to following error in java console. but how to slove it?? The file "./image.jpg" is missing or inaccessible, make sure the URL is valid or that the file has been added to your sketch and is readable.

Are you using proper directives? http://processingjs.org/reference/pjs directive/

There are three things to try

1) The size() statement should be the first on in setup() so change it to

void setup() {
  size(465, 600);
  llegeixImatge("./"+iName);
}

2) You might also try changing line 3 to

llegeixImatge(iName);

3) In your sketch folder create a new folder called data and put the image in there.

I tried all the above solution but still getting same error in java console that image is missing or inaccessible.

quark

The solution is

void setup() {
  size(465, 600);
  llegeixImatge(iName);
}

and make sure the image is in a folder called data inside the sketch folder.
