位图具有轮廓

感谢任何线索。

解决方案

您可以使用imagemagick做到。尽管有ImageMagick的PHP API，但我认为异步生成/执行convert命令并从FS读取输出图像更加容易和安全得多

我从此讨论

I am working on a project that requires creating an outer contour from a bitmap image. eg. please check the images below. Is there any php library that I can use to achieve this task? I have found open source library http://docs.opencv.org/trunk/d4/d73/tutorial_py_contours_begin.html but this is not on php

bitmap image only

bitmap with contour

Thanks for any clues.

解决方案

You can do it with imagemagick. Although there's a PHP API for ImageMagick, I think it's much easier and safer to just spawn/execute asynchronously the convert command and read the output images from FS
