Question

我制作了一个python脚本，用graphviz绘制目录结构。为了正确渲染图形，我使用rankdir = LR。但是，具有相同等级的节点居中。

见下图。

Graph result

正如您所看到的，“。gitignore”，“。travis.yml”等节点由于其标签而不具有相同的宽度。我希望无论宽度如何，左侧都有相同等级的节点。

我见过其他相关帖子，例如this one，但我不想强制节点宽度。

还有其他办法吗？

提前感谢您的回答并度过愉快的一天。

P.S .: 以下是我的图表代码示例：

经过一些研究并感谢@TomServo，我已经能够“修复”节点宽度。

我使用以下代码。可以找到ImageFont doc here

font = ImageFont.truetype('DejaVuSansMono.ttf', FONT_SIZE)
width = font.getsize("YOUR STRING TO MEASURE HERE")[0]
# convert pixels to inches and add extra space for icons and margins
# icon size is defined as points which is a 72's of an inch
width = width / GRAPHVIZ_DPI + ((1 / 72) * 20 * 2)

然后结果：

Graphviz：在左侧对齐节点而不是居中（有答案）
