Small library for converting DOT (graph description language) to various image formats (svg, jpeg, png)

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.

What things you need to install the software and how to install them

• sbt 0.13 or greater if you want to build from source
• JVM 8 for the Scala 2.12 build, JVM 6+ for the 2.11 build

If you're using Maven simply specify the GAV coordinate below and Maven will do the rest

<dependency>
  <groupId>org.bradfordmiller</groupId>
  <artifactId>dot2img_2.11</artifactId>
  <version>0.0.21</version>
</dependency>

Add this GAV coordinate to your SBT dependency list

libraryDependencies += "org.bradfordmiller" %% "dot2img" % "0.0.21"

Building the library requires SBT 0.13+ and a 1.8 version of the JDK for the Scala 2.12 version, or a 1.6+ version of the JDK for the Scala 2.11 version

You can build the library with this command

sbt publishLocal

The resulting jar will be published to ~/.ivy2/local/org/bradfordmiller/dot2img_{SCALA_VERSION}

The library is quite simple. Feed in your dot grammar as a string along with an output path as seen below

import org.bradfordmiller.dot2img
...

//Set up your dot data
val data = "digraph G {\n  \"Welcome\" -> \"To\"\n  \"To\" -> \"Web\"\n  \"To\" -> \"GraphViz!\"\n}"

val p = Dot2Img.save(data, "/tmp/testformat.jpg")

println(p)

The saved image will be at the path in the appropriately specified format. Currently svg, jpeg and png are supported.

The above code will produce the following image:

• scala - The programming language
• Apache Batik - SVG image conversion
• viz.js - Javascript rendering engine for dot grammar

For the versions available, see the tags on this repository.

• Bradford Miller - Initial work - bfm

• This library wraps viz.js to do the heavy lifting with the graphics rendering as seen here
