我有一个2D数组,其中包含来自C#中以数值方式解决的传热问题的温度数据。为了可视化温度分布,我使用了“位图”。最低的温度用蓝色表示,而最热的用红色表示!
问题在于,生成300x300图像尺寸的位图需要花费太多时间!当我尝试与较大的打印机一起工作时,这是不可能的!
有没有更有效的方法来使其工作?
任何帮助将不胜感激
这是我的一些代码和一个生成的位图:
enter image description here
//RGB Struct
struct RGB
{
public Int32 num;
public int red;
public int green;
public int blue;
public RGB(Int32 num)
{
int[] color = new int[3];
int i = 2;
while (num > 0)
{
color[i] = num % 256;
num = num - color[i];
num = num / 256;
i--;
}
this.red = color[0];
this.green = color[1];
this.blue = color[2];
this.num = (256 * 256) * color[0] + 256 * color[1] + color[2];
}
}
//Create Color Array
Int32 red = 16711680;
Int32 blue = 255;
Int32[,] decimalColor = new Int32[Nx, Ny];
for (int i = 0; i < Nx; i++)
{
for (int j = 0; j < Ny; j++)
{
double alpha = (T_new[i, j] - T_min) / (T_max - T_min);
double C = alpha * (red - blue);
decimalColor[i, j] = Convert.ToInt32(C) + blue;
}
}
//Bitmap Result
Bitmap bmp = new Bitmap(Nx, Ny);
for (int i = 0; i < Nx; i++)
{
for (int j = 0; j < Ny; j++)
{
RGB rgb = new RGB(decimalColor[i, j]);
bmp.SetPixel(i,j,Color.FromArgb(rgb.red,rgb.green,rgb.blue));
}
}
pictureBox1.Image = bmp;
