VectorGraphics2D

VectorGraphics2D provides implementations of Java's Graphics2D interface and exports the graphics in various vector file formats. Currently, there's support for the following vector file formats:

Additional formats can be easily added.

Features

Currently, most operations are supported, i.e. VectorGraphics2D is able to handle clipping gradients, or compression. Some features are still missing, like text encodings, embedded fonts, or metadata support. Although its early stage VectorGraphics2D is already used successfully in several projects to export vector graphics.

Requirements

VectorGraphics2D requires at least Java 8 and Gradle 5 or higher to build.

Installation

Without build management system

You can just add VectorGraphics2D-0.13.jar to the classpath of your project.

Using VectorGraphics2D with Gradle

.. code:: groovy dependencies { compile group: 'de.erichseifert.vectorgraphics2d', name: 'VectorGraphics2D', version: '0.13' }

Usage

A VectorGraphics2D object can be used as a replacement for a Graphics2D object. All calls to the VectorGraphics2D instance will be recorded and can later be retrieved as a CommandSequence:

.. code:: java

Graphics2D vg2d = new VectorGraphics2D();
vg2d.draw(new Rectangle2D.Double(0.0, 0.0, 20.0, 20.0));
CommandSequence commands = ((VectorGraphics2D) vg2d).getCommands();

This command sequence can then be exported to a EPS, PDF or SVG document using a processor for the desired file type, i.e. EPSProcessor for EPS, PDFProcessor for PDF and SVGProcessor for SVG. Additionally, format specific output options can be passed to the processor when it is created. For example, a compression option can be passed for PDF:

.. code:: java

PDFProcessor pdfProcessor = new PDFProcessor(true);

Another method to get a processor is Processors.get(String):

.. code:: java

Processor pdfProcessor = Processors.get("pdf");

Finally, a document can be generated from the commands and written to an output stream:

.. code:: java

Document doc = pdfProcessor.getDocument(commands, PageSize.A4);
doc.writeTo(new FileOutputStream("rect.pdf"));
