batik-rasterize

Clojure batik wrapper for rasterizing SVG graphics.

Inspired by Clojure dali library.

Clojars Project

Usage

Add dependency

[batik-rasterize "0.1.2"]

require it

(require '[batik.rasterize :as b])

and rasterize SVGs!

Functions

(b/parse-svg-uri "https://github.com/HausnerR/batik-rasterize/blob/master/clj_logo.svg")
(b/parse-svg-uri "clj_logo.svg")

Creates batik SVG document object from file/uri

(b/parse-svg-string "<?xml version="1.0" encoding="UTF-8" standalone="no"?><svg>...</svg>")

Creates batik SVG document object from given SVG string

(b/render-svg-document document filename options)

Render rasterized version of SVG document, and save it at filename path.

Filename can be nil then result is returned as byte-array.

Available optional options:

  • :width - define output image width. By default it tries to determine width from source SVG,
  • :scale - you can define scale instead of width (2 times bigger, 0.5 times bigger etc.),
  • :type - output type. Possible values :jpg, :jpeg, :tif, :tiff, :png. Default by output extension,
  • :quality - define JPEG output quality. By default 95%
(b/render-svg-uri "clj_logo.svg" filename options)

Conjunction of parsing uri & rendering in one function

(b/render-svg-string "<?xml version="1.0" encoding="UTF-8" standalone="no"?><svg>...</svg>" filename options)

Conjunction of parsing SVG string & rendering in one function

Known bugs

Due to bug in batik library, exporting to JPEG doesn't work :(
