Retrieving Pixel Data from an image

well i seem to have used the grabpixel to grab the pixels that i wanna check, but to say that there is some slow down would be an understatement, the game barely crawls!!

there must be a quicker way (bearing in mind im only using the pixel grabber to only grab pixels) of doing this, because the slow down is terrible!! - oh and it has to work with the microsoft virtual machine, not suns official virtual machine

heres the code that uses pixelgrabber, as you can see its only checking 3 pixels, but the slow down is so high, its unplayable

int return_value=0;

PixelGrabber pg=new PixelGrabber(offscreen,ball_X+15,ball_Y+33,3,1,pixels,0,3);

try{

pg.grabPixels();

}catch(InterruptedException e){}

test=createImage(new MemoryImageSource(3,1,pixels,0,3));

/*CHECK TO SEE IF BALL IS STALL ON THE PLAY AREA

*0=dead

*1=safe

*2=slow down

*3=speed up

*4=jump

*5=reverse

*6=finsih */

switch(pixels[0]){

//safe

case 0xff808080: return_value=1; break;

case 0xffc0c0c0: return_value=1; break;

//slow down

case 0xff800080: return 2;

case 0xffff00ff: return 2;

//speed up

case 0xff800000: return 3;

case 0xffff0000: return 3;

//jump

case 0xff000080: return 4;

case 0xff0000ff: return 4;

//reverse

case 0xff808000: return 5;

case 0xffffff00: return 5;

//finish

case 0xff008000: return 6;

case 0xff00ff00: return 6;

}

switch(pixels[2]){

//safe

case 0xff808080: return 1;

case 0xffc0c0c0: return 1;

//slow down

case 0xff800080: return 2;

case 0xffff00ff: return 2;

//speed up

case 0xff800000: return 3;

case 0xffff0000: return 3;

//jump

case 0xff000080: return 4;

case 0xff0000ff: return 4;

//reverse

case 0xff808000: return 5;

case 0xffffff00: return 5;

//finish

case 0xff008000: return 6;

case 0xff00ff00: return 6;

}

return return_value;

yeah, so its a bit of a ****** cos its JUST SO GOD **** SLOW!! (sorry i know i keep repeating myself, but its really fu***** me off!)
