Creating Cells Text Extraction. Batik SVG Toolkit. Overview 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. The project’s ambition is to give developers a set of core modules that can be used together or individually to support specific SVG solutions. Examples of modules are the SVG Parser, the SVG Generator and the SVG DOM. Another ambition for the Batik project is to make it highly extensible —for example, Batik allows the developer to handle custom SVG elements. Even though the goal of the project is to provide a set of core modules, one of the deliverables is a full fledged SVG browser implementation which validates the various modules and their inter-operability.
What Batik can be used for With Batik, you can manipulate SVG documents anywhere Java is available. Batik makes it easy for Java based applications or applets to deal with SVG content. The Batik toolkit includes the following: Busy Developers' Guide to HSSF and XSSF Features. Busy Developers' Guide to Features Want to use HSSF and XSSF read and write spreadsheets in a hurry?
