c#实现巴恩斯利蕨,运行出问题,求助解决
代码如下,一个菜单栏一个picturebox控件,一运行就卡死,显示是Bitmap myBitmap = new Bitmap(pictureBox1.Width, pictureBox1出了问题,但是不完全知道怎么改啊哭
private void showToolStripMenuItem_Click(object sender, EventArgs e)
{
int r;
double x, y;
x = 0.0; y = 0.0;
Random ra = new Random(0);//种子
for (int i = 0; i < 50000; i++)
{
Random ran = new Random();
r = ran.Next()%100;//随机数
if (r< 0)
{
x = 0;
y = 0.16 * y;
}
else if (r<8)
{
x = 0.2 * x - 0.26 * y;
y = 0.23 * x + 0.22 * y + 1.6;
}
else if (r<15)
{
x = -0.15 * x + 0.28 * y;
y = 0.26 * x + 0.24 * y + 0.44;
}
else
{
x = 0.85 * x + 0.04 * y;
y = -0.04 * x + 0.85 * y + 1.6;
}
Bitmap myBitmap = new Bitmap(pictureBox1.Width, pictureBox1.Height);
myBitmap.SetPixel((int)((x / 10)), (int)((y / 10 - 0.3)), Color.Green);
pictureBox1.Image = myBitmap;
}
}
