No library found for krister.Ess

noonjaka

I have made this code to make our face star, triangle, or rectangle pixels on webcam. but the processing program keeps saying that there is no library found for krister.Ess Libraries must be installed in a folder named 'libraries' inside the 'sketchbook' folder. I have already downloaded and put this in a libraries inside the sketchbook folder. I don't know what is the problem. Please help me! The code below is what I made.

PImage img;

PImage pnimg;




import processing.video.*;

import krister.Ess.*;

FFT myfft;

AudioInput myinput;

int bufferSize=512; 

import processing.video.*;




// Size of each cell in the grid

int cellSize = 8;

// Number of columns and rows in our system

int cols, rows;

// Variable for capture device

Capture video;

PShape star;




int status = 0;

int ready = 0;

int count = 0;




void setup() {

size(1024,768,P3D);

background(0, 102, 153);

img = loadImage ("back06.jpg");

// Set up columns and rows

cols = width/2 / cellSize;

rows = height/2 / cellSize;

//colorMode(RGB, 255, 255, 255, 70);

// ellipseMode(CENTER);



// Uses the default video input, see the reference if this causes an error

video = new Capture(this, 640, 480);

video.start();

frameRate(45); 

//filter(BLUR,30);

smooth();




Ess.start(this); 

myinput=new AudioInput(bufferSize);

myfft=new FFT(bufferSize*2);

myinput.start();




myfft.damp(.1);

myfft.equalizer(true);

myfft.limits(.005,.01);




}

tint(255,70);

if (video.available()) {

video.read();

video.loadPixels(); 




// Begin loop for columns

for (int i = 0; i < cols;i++) {

// Begin loop for rows

for (int j = 0; j < rows;j++) {




// Where are we, pixel-wise?

int x = i*cellSize + cellSize/2;

int y = j*cellSize + cellSize/2;

int loc = (video.width - x - 1) + y*video.width; // Reversing x to mirror the image



// Each rect is colored white with a size determined by brightness

color c = video.pixels[loc];

float sz = ((percent)*5000/ float(width)) * brightness(video.pixels[loc]) + 80.0;

float sy = brightness(video.pixels[loc])+20.0;

pushMatrix();

Since Processing is saying that it can't find the library then it is either a problem with the import statement or the library has been placed in the wrong folder. It is NOT caused by errors in your source code. (When posting code in this forum, select the code and press K or click on the C button).

The problem is almost certainly that you have put the library in the wrong place. It should be

Process
     |-- Libraries
               |-- Ess
                    |-- library
                            |-- Ess.jar
