如何从Graphics2D捕获图形基元到SVG [英] how to capture graphics primitives from Graphics2D into SVG

问题描述

我需要从调用java.awt.Graphics2D中捕获图形基元。调用是通过开源工具包（Apache的PDFBox）进行的，通常在JPanel中呈现。我想拦截这些调用并将它们转换为SVG，这样我就可以构建一个非图形数据模型（例如表格，图形等）。我会很高兴在这个阶段的任何类型的黑客，其中可能包括：

I need to capture the graphics primitives from calls to java.awt.Graphics2D. The calls are made through an Open Source toolkit (Apache's PDFBox) and normally rendered in a JPanel. I would like to intercept these calls and translate them to SVG so I can build a non-graphics data model (e.g. tables, graphs, etc.). I'll be happy for any type of hack at this stage, which might include:

• 用MyGraphics2D替换Graphics2D库


• 查找支持SVG输出并捕获


• 的Graphics2D拦截对Graphics2D的调用（我不喜欢因为我必须管理仿射变换）

辅助问题：Graphics2D是否使用图形库？在这种情况下，如果我在此级别捕获应该已应用转换。

Subsidiary question: Does Graphics2D use the Graphics library? In which case if I capture at this level the transformations should have been applied.

推荐答案

我会看看 Batik 项目，提供Graphics2D的扩展以输出SVG文件。

I would have a look at the Batik project which provides an extension of Graphics2D to output SVG files.
