使用JFreeChart和Apache PDFBOX生成图表 [英] Generate chart with JFreeChart and Apache PDFBOX

问题描述

我需要使用 JFreeChart 生成图表，然后使用

I need to generate charts using JFreeChart and then export them to PDF using Apache PDFBOX. I don't want to use iText as it cannot be used in proprietary software.

我搜索了整个Google，但没有运气！有人做过吗?

I searched all over Google, but no luck! Has anyone done it?

推荐答案

从PDXObjectImage的InputStream .org/repos/asf/pdfbox/trunk/examples/src/main/java/org/apache/pdfbox/examples/pdmodel/AddImageToPDF.java"rel =" nofollow noreferrer> AddImageToPDF . 此处显示了典型的copyStream()实现.

Copy the OutputStream from your chosen writeChartAs*() method in ChartUtilities to the InputStream used to create a PDXObjectImage in AddImageToPDF. A typical copyStream() implementation is shown here.

附录:或者，使用管道流从输出复制到输入，如此处和此处.

Addendum: Alternatively, use piped streams to copy from output to input, as shown here and here.
