hi all

推荐答案

//the width and height of your screen.
int width = 640;
int height = 480;

//The average white pixels of x and y.
int average_x;
int average_y;

//counts the x and y axis.
int count_x = 0;
int count_y = 0;

//tells you how many white pixels there are.
int count = 0;

//Make a for loop for the x axis and the y axis.
for(int a = 0; a < width; a = a+1;){
for(int b = 0; a < height; b = b+1;){

//If the pixel is white
if(pixel(a, b) == white)
{
count = count+1;
count_x = count_x+a;
count_y = count_y+b;
}

}
}

//Calculate the average x and y axis for the white pixels.
average_x = count_x/count;
average_y = count_y/count;

平均值_x和平均值_y是您想要的中心轴.

The average_x and average_y are the center axis you want.
