C＃抗锯齿算法

Question

我想在C＃中编写自己的抗锯齿算法。我的照片只有两种颜色;黑与白。

在维基百科（https://en.wikipedia.org/wiki/Spatial_anti-aliasing）上，我找到了以下pseudecode：

Define function PlotAntiAliasedPoint ( number x, number y )
    For roundedx = floor ( x ) to ceil ( x ) do
         For roundedy = floor ( y ) to ceil ( y ) do
              percent_x = 1 - abs ( x - roundedx )
              percent_y = 1 - abs ( y - roundedy )
              percent = percent_x * percent_y
              DrawPixel ( coordinates roundedx, roundedy, color percent (range 0-1) )

如何在C＃中实现这个伪代码？

Answer 1

private void PlotAntiAliasedPoint(decimal x, decimal y)
{
  for (var roundedx = Math.Floor(x); roundedx <= Math.Ceiling(x); roundedx++)
  {
    for (var roundedy = Math.Floor(y); roundedy <= Math.Ceiling(y); roundedy++)
    {
      var percent_x = 1 - Math.Abs(x - roundedx);
      var percent_y = 1 - Math.Abs(y - roundedy);
      var percent = percent_x*percent_y;
      //DrawPixel(coordinates roundedx, roundedy, color percent(range 0 - 1))
    }
  }
}
