我编写了一个宏，它给出了一条直线，将其分成等长的段，并生成一系列垂直线穿过每个段的起点/终点。宏是（对不起，如果它看起来很基本，但我只是在学习这些东西......）：

getLine(x0,y0,x11,y11,width);
dx = x11 -x0;
dy = y11 -y0;
xstep = dx/11;
ystep = dy/11;

// Interpolate segment points
xs=x0 - 1xstep
x1 = x0 + 1xstep;
x2 = x0 + 2xstep;
x3 = x0 + 3xstep;
x4 = x0 + 4xstep;

x5 = x0 + 5xstep;
x6 = x0 + 6xstep;
x7 = x0 + 7xstep;
x8 = x0 + 8xstep;
x9 = x0 + 9xstep;
x10 = x0 + 10xstep;
x11 = x0 + 11xstep;
x12 = x0 + 12xstep;
x13 = x0 + 13xstep
ys=y0 - 1ystep
y1 = y0 + 1ystep;
y2 = y0 + 2ystep;
y3 = y0 + 3ystep;
y4 = y0 + 4ystep;
y5 = y0 + 5ystep;
y6 = y0 + 6ystep;
y7 = y0 + 7ystep;
y8 = y0 + 8ystep;
y9 = y0 + 9ystep;
y10 = y0 + 10ystep;
y11 = y0 + 11ystep;
y12 = y0 + 12ystep;
y13 = y0 + 13ystep;

// Create sections at regular intervals along the strait line

makeLine(xs, ys, x1, y1);
Roi.setStrokeColor(255,126,0);
run(“Rotate…”, “angle=90”);
roiManager(“Add”);

makeLine(xs, ys, x3, y3);
Roi.setStrokeColor(255,126,0);
run(“Rotate…”, “angle=90”);
roiManager(“Add”);

makeLine(x0, y0, x4, y4);
Roi.setStrokeColor(255,126,0);
run(“Rotate…”, “angle=90”);
roiManager(“Add”);

makeLine(x1, y1, x5, y5);
Roi.setStrokeColor(255,126,0);
run(“Rotate…”, “angle=90”);
roiManager(“Add”);

makeLine(x2, y2, x6, y6);
Roi.setStrokeColor(255,126,0);
run(“Rotate…”, “angle=90”);
roiManager(“Add”);

makeLine(x3, y3, x7, y7);
Roi.setStrokeColor(255,126,0);
run(“Rotate…”, “angle=90”);
roiManager(“Add”);

makeLine(x4, y4, x8, y8);
Roi.setStrokeColor(255,126,0);
run(“Rotate…”, “angle=90”);
roiManager(“Add”);

makeLine(x5, y5, x9, y9);
Roi.setStrokeColor(255,126,0);
run(“Rotate…”, “angle=90”);
roiManager(“Add”);

makeLine(x6, y6, x10, y10);
Roi.setStrokeColor(255,126,0);
run(“Rotate…”, “angle=90”);
roiManager(“Add”);

makeLine(x7, y7, x11, y11);
Roi.setStrokeColor(255,126,0);
run(“Rotate…”, “angle=90”);
roiManager(“Add”);

makeLine(x8, y8, x12, y12);
Roi.setStrokeColor(255,126,0);
run(“Rotate…”, “angle=90”);
roiManager(“Add”);

makeLine(x10, y10, x12, y12);
Roi.setStrokeColor(255,126,0);
run(“Rotate…”, “angle=90”);
roiManager(“Add”);

makeLine(x0, y0, x11, y11);
Roi.setStrokeColor(255,126,0);
roiManager(“Add”);
run(“Measure”);

在某些情况下，我需要使用分段线/折线获得相同的结果。为了更好地“模拟”我想要测量的对象的形状，我将样条曲线拟合到我的折线。这很容易做到。如何将样条线分成相等的段并在每个样条的开始/结束处运行一条垂直线？任何帮助是极大的赞赏。到目前为止，这就是我拼凑起来的：

makeLine(x100, y100, x101, y101, x103, y103);
run("Properties… ", “stroke=red”);
roiManager(‘add’);
run(“Fit Spline”);
run("Properties… ", “stroke=green”);
roiManager(‘add’);
run(“Measure”);
