在python中将点转换为png [英] Converting dot to png in python

问题描述

我有一个从代码生成的点文件，想要在输出中呈现它.为此，我在网上看到该命令在cmd

I have a dot file generated from my code and want to render it in my output. For this i have seen on the net that the command is something like this on cmd

dot -Tpng InputFile.dot -o OutputFile.png  for Graphviz

但是我的问题是我想在我的python程序中使用此内置函数.

But my problem is that I want to use this inbuilt in my python program.

我该怎么做??

我看着pydot，但似乎找不到答案.....

I looked at pydot but can't seem to find an answer in there.....

推荐答案

pydot 需要无论如何都将安装GraphViz二进制文件，因此，如果您已经生成了点文件，则不妨直接自己直接调用点.例如:

pydot needs the GraphViz binaries to be installed anyway, so if you've already generated your dot file you might as well just invoke dot directly yourself. For example:

from subprocess import check_call
check_call(['dot','-Tpng','InputFile.dot','-o','OutputFile.png'])
