如何从 XY 坐标数组中添加列表框中的 n 个项目

Question

我有一张 Blob 图像，我将其 COG 转换为 XY 坐标 Apoints[i] 数组。我想将这些坐标添加到列表框中。根据图像的不同，可以有 0 到最多 300 个 XY 点。我有一个语法，我想将它们添加如下：

P1 = (Y,X,0.0,0.0,0.0,0.0)(0,0)
P2 = (Y,X,0.0,0.0,0.0,0.0)(0,0)
.
.
.
P300 = (Y,X,0.0,0.0,0.0,0.0)(0,0)

在列表框中换行

但是点可以是 0 到 300 之间的任意值，并且不是固定的，它取决于图像。有些图像可能有o点，所以不需要添加。有些图像可能有 20 个点，所以我需要 P1 到 P20。我不知道该怎么做。

Answer 1

我认为

• 您可以使用循环遍历Apoints[]
• Apoint[i] 具有 X 和 Y 属性
• "P1 = (Y,X,0.0,0.0,0.0,0.0)(0,0)" 是一个字符串
• 您可以通过某种方式计算图像的点数

如果我错了就告诉我...

然后你可以这样做：

var n = GetNumberOfPointsInImage()
for(var i=0; i<n; i++){
  var y = Apoints[i].y;
  var x = Apoints[i].x;
  var p = $"P{i} = ({y},{x},0.0,0.0,0.0,0.0)(0,0)";
  myListBox.Items.Add(p);
}
