Mermaid Diagram Image Export

mermaid-image-export.md

We can export a mermaid diagram to PNG very simply using the official Mermaid CLI Tool.

Installation via npm

npm i -g mermaid.cli

Usage:

mmdc -i ${input_file_location} -o ${output_file_location}

Example

echo 'sequenceDiagram\nAlice ->> Bob: Hey, Bob!\nBob ->> Alice: Hey there, Alice!' > /tmp/alice-bob.mmd
mmdc -i /tmp/alice-bob.mmd -o /tmp/alice-bob.png
open /tmp/alice-bob.png

Bonus Round

We can combine using mmdc to create images from Mermaid diagrams with creating data URLs from the command line (as illustrated here) to include Mermaid diagrams into markdown files where the rendering engine does not support mermaid diagrams but does support data URIs.

data_url="data:image/png;base64,$(base64 < /tmp/alice-bob.png)"

Result of this is the following base 64 string

Hi Friedrich,

I have a question about the PNG resolution. I tried to create a PNG for my .mmd which is a little bigger than usual. When I enlarge the resulting PNG, the quality is a little bit too low. Do you have suggestions on how to enhance the quality?

This is my sample .mmd
