Based on your comments/answers, this is What I did to obtained an "approximate solution":
这是一个图示,其中特定的小右矩形中包含的特征的部分反映在相应的小左矩形中。
Looks like reflection in a line. If the line is not "straight" it looks like a polyline.
I see no curves, arcs etc. (also you can always stroke a non line)
If all or some of the lines of the polyline have different angles, then you are warping your object. Or in your example, as they are point objects, displacing geographic features. (lidar samples or something)
和你似乎反映线(段)st to the objects.
Looks visibly warped.
你为什么要这样做的是geo功能?
The reflection question has been posted on this forum before by the way.
On the screen shot, I zoommed in a lot just to illustrate the methodology. There are some cases where the reflection has to be done on a line having an arc shape or an S-shape.
I'm not reflecting to the closest object. I used the small rectangles to split the object and it is only the part included in that small rectangle that will be reflected. In the previous image, I only show the part of the object that was included in one of those small rectangles.
I'm going to use the reflected objects in combination with the original objects to create a worst case scenario of possible obstruction of any structure over or beside a railway track.
It is possible to do that, though the calculation is much more difficult (often very much so ).
这也是一个伸展的结果是“反射”。它更像是一个笑的镜面反射。
You end up with distortions up to extremes.
Depending on the curve and weather it can be described as a single function.
I don't see any apparent use for such in Geography.
I'm wondering if@arthyis talking polylines. Which are still lines.
反映折线的细分提出了问题,就像你认为反射一样。
AS you can reflect anything in any line.
So reflecting in a polyline might also be considered as reflecting in any line segment of the polyline.
那么你在哪里设置了你的界限?
我将使用带有变压器。
If I understand the math correctly the parameters should be
A :( 1-M ^ 2)/(1 + M ^ 2)
B: 2m/(1+m^2)
C: -2mb/(1+m^2)
D: 2m/(1+m^2)
E: (m^2-1)/(1+m^2)
F: 2b/(1+m^2)
对于y = mx + b线
If the line is the y-axis it simplifies to -1 0 0 0 1 0
If the line is the x-axis it simplies to 1 0 0 0 -1 0
Hello@jdh
It is a line from an FME perspective (i.e. with multiple vertices) not from a math perspective.
It wouldn't be possible to describve the line with an equation like y =mx +b
