java - int[] to BufferedImage -

i'm trying filter image. first, put rgb values inside int[][] , filter. in next step have convert int[][] int[] , want display new image again. code:

 int row,col,count=0;           int[] pixels = new int[width*height];              while(count!=(pixels.length)){                    for(row=0;row<height;row++){                      for(col=0;col<width;col++){                          pixels[count] = imagearray[row][col];                          count++;                      }                 }             }               bufferedimage image = new bufferedimage(width, height, bufferedimage.type_int_rgb);              writableraster raster = (writableraster) image.getdata();               raster.setpixels(0,0,width,height,pixels); //the problem appear in line 

and error.

exception in thread "main" java.lang.arrayindexoutofboundsexception: 181000 @ java.awt.image.singlepixelpackedsamplemodel.setpixels(unknown source) @ java.awt.image.writableraster.setpixels(unknown source)

i check types, size of both arrays , don't know can do.

the first array, int[][], created next code:

int[][] imagearray = new int[height][width]; //...dar tamaño al array donde guardaremos la imagen            (int row = 0; row < height; row++) { //en este doble bucle vamos guardando cada pixel              (int col = 0; col < width; col++) {                  imagearray[row][col] = image.getrgb(col, row);                      }                   } 

arrays in java 0 based, therefore

int[] array = {1,2,3}; 

will have length of 3, maximum element reference of 2 and

while( count <= array.length ) {     system.out.println( array[count] );     ++count; } 

will overrun array because while doesn't fail until count == array.length, or 3, , array[3] doesn't exist.

use while( count < array.length ) instead
