If you use a transcoder that inherits from the XMLAbstractTranscoder class, there is a limited support for it (the first SVG element is used as the new root). But do not forget to set these hints:
transcoder.addTranscodingHint(XMLAbstractTranscoder.KEY_DOCUMENT_ELEMENT_NAMESPACE_URI,
"http://www.w3.org/1999/xhtml");
transcoder.addTranscodingHint(XMLAbstractTranscoder.KEY_DOCUMENT_ELEMENT, "html");In the rest of the old API, you can't (please see #40). You have to import the SVG subtree into a new DOM document.
However, with the new CSSTranscodingHelper you can specify a selector pointing to any of the SVG elements in your document, so it is used as the SVG root.
See above, you have to appropriately set the KEY_DOCUMENT_ELEMENT_NAMESPACE_URI and KEY_DOCUMENT_ELEMENT hints.
EchoSVG uses the java.awt package which is not available on Android. Although a library like android-awt may be used, this project is unaware of anyone succeeding. Also, a parser-related issue has been reported.
EchoSVG's DOM implements an old version of the CSS Object Model and allows programmatic manipulation of CSS2 style sheets. If your styles are limited to CSS2 you can use it, but beware that the old CSSValue API is deprecated and may be replaced.
If you want to use modern CSS, you may want to process your document with css4j first, then feed it to EchoSVG.
Does this project support Houdini's Typed OM?
For now, this project uses the old (and deprecated) CSSValue API. If you are interested in the switch to Typed OM, please comment on issue #67.
No it is not, as its maintainer does not accept Maven Central's Terms of Use. The distribution is through the css4j Maven repository instead.
Only software coming from the Apache Software Foundation (ASF) source repositories can be used in org.apache packages. If you look at the point 6 of the ASF license 2.0:
- Trademarks. This License does not grant permission to use the trade names, trademarks, service marks, or product names of the Licensor, except as required for reasonable and customary use in describing the origin of the Work and reproducing the content of the NOTICE file.
The term "Apache" is a registered trademark by the ASF (registration number 5906264) and can only be used for attribution. "Apache Batik" is a product name and similar considerations apply.
No you cannot. Submitting code to any Apache Software Foundation (ASF) project implies assigning the copyright to the ASF. Instead, EchoSVG uses a Developer Certificate of Origin copyright model, so contributors keep their copyright.
You cannot assign to the ASF the copyright that you do not own.
The codec and transcoder jar files were a bit entangled in Apache Batik, as they have a runtime circular dependency there. And this often confused people, see:
- https://stackoverflow.com/questions/45239099/apache-batik-no-writeadapter-is-available
- https://bz.apache.org/bugzilla/show_bug.cgi?id=44682
so in EchoSVG both modules were merged. As a result, there is no codec module or Jar file. You only need echosvg-transcoder.
[0.1.x only] java.lang.module.FindException: Module xalan not found, required by io.sf.carte.echosvg.dom
The module system is refusing to create a filename-based module name from the Xalan jar file because it is finding a declaration of a non-existent service provider.
The solution is to upgrade to EchoSVG 0.2 or later (that do not depend on Xalan) but if you cannot do that, the workaround is to use a plugin to force the declaration of a module name.
With Gradle you can use either the extra-java-module-info plugin:
plugins {
id 'org.gradlex.extra-java-module-info' version '1.0'
}
extraJavaModuleInfo {
failOnMissingModuleInfo.set(false)
automaticModule('xalan:xalan', 'xalan')
}or the moditect-gradle-plugin.
With Maven, you could use the Moditect Maven plugin.
Yes there are a few open source projects that use EchoSVG, and Carte is a relatively simple one that you could look at (see SVGtoRaster.java).
