计算与多边形的几何偏移 [英] Calculate geometric offset from a polygon

问题描述

我正在尝试从多边形执行偏移功能.
我必须偏移的主要多边形是这样的:

推荐答案

取决于您的多边形是什么(图像，点数组等)，您可能可以使用矩阵转换.如果是这样，使用.NET GDI +的C#中的图像矩阵转换 [

Depending on what your Polygon is (Image, Array of Point etc....) you might be able to use a Matrix Translation. If so Matrix Transformation of Images in C#, using .NET GDI+[^] might be of some use.

也许如果您解释了您要尝试的操作...

Perhaps if you explain what you''re trying to do...

要偏移多边形，您要做的就是将所需尺寸的偏移量添加到每个顶点/坐标.

To offset the polygon, all you have to to is add the offset, in required dimension, to each vertex/coordinate.
