EchoSVG

EchoSVG is a fork of Apache Batik, a Java based toolkit for applications which handle images in the Scalable Vector Graphics (SVG) format for various purposes, such as viewing, generation or manipulation.

Supports level 4 CSS selectors and RGBA color values (colors with alpha channel), as well as other improvements over Batik.


SVG support

Like Batik, EchoSVG is built on SVG 1.1 although also supports part of the (deprecated) SVG 1.2 specification.


CSS support

The SVG 1.1 standard is based on CSS2, however EchoSVG natively supports RGB colours with an alpha channel, as well as level 4 selectors.

And with the CSSTranscodingHelper, it can render many documents that use modern CSS. For an example of the CSS that can be processed with EchoSVG, please look at this sample test file featuring custom properties, @supports and level 4 @media rules.


Java Runtime

EchoSVG is compatible with Java 8 and later, although module-info files are provided for modular JDKs.


Why EchoSVG instead of Batik?
