How can I square(^2) the pic in the grid?

public Picture makeGrid(int size)
{
Picture targetPicture = new Picture(this.getWidth()*size, this.getHeight()*size);
Pixel sourcePixel = null;
Pixel targetPixel = null;
int targetX = 0;
int targetY = 0;

//loop through the source picture columns
for(int sourceX = 0; sourceX < this.getWidth(); sourceX++)
{
//loop through the source picture rows
for(int sourceY = 0; sourceY < this.getHeight(); sourceY++)
{
// get the source pixel
sourcePixel = this.getPixel(sourceX,sourceY);

// loop copying to the target y
for(int indexY = 0; indexY <size; indexY++)
{
// loop copying to the target x
for(int indexX = 0; indexX < size; indexX++)
{
targetX = sourceX + size*2 + indexX;
targetY = sourceY + size*2 + indexY;
targetPixel =targetPicture.getPixel(targetX, targetY);
targetPixel.setColor(sourcePixel.getColor());
}
}
}
}
return targetPicture;
}

my code give the following result:

for makeGrid(2)


for makeGrid(3)



But the code should work like this as show:

what do you mean by replies ? Nobody gave me a reasonable answer.
