Batik

Batik (xmlgraphics.apache.org/batik/) is a Java-based toolkit for applications or applets that want to use images in the Scalable Vector Graphics (SVG) format for various purposes, such as display, generation or manipulation.

Quick Start

Be sure to add your batik installation to the classpath.

Rasterization

# Create a transcoder
transcoder = Batik::Transcoder.new

# Transcode an svg string to a string as a PNG
png = transcoder.to_png(svg_document)

# Transcode an svg string to a string as a JPEG
jpeg = transcoder.to_jpeg(svg_document)

# Transcode an svg string to a string as a PNG with some options
png = transcoder.to_png(svg_document, :dpi => 600, :indexed => 8)

# Transcode an svg string to a file
File.open('new.png', 'wb+') { |fp|
  fp.write(transcoder.to_png(svg_document))
}
