I have a task to choose a Java PDF libraries for PDF generation.
1. Can write table directly into PDF. So that the table is scalable compared to a table image.
2. Support for writing SVG image into PDF.
The lib I finally choose is iText
Finally I choose iText. Because iText has a lot of documentation and tutorial. The book “ITEXT IN ACTION – SECOND EDITION” is a an excellent book, however it’s not free. But there’s collection of “the best Q&A in 250 pages”, which helps you find fast and creative solutions for any iText project. ITEXT is not commercial free. The fee is $1325 / 1025€ for a pack of 10 desktops. ITEXT Desktop License detail.
At the first, I use apache PDFBox, which is commercial free. But I found that PDFBox cannot write table into PDF directly. If it’s for this reason, I wouldn’t choose ITEXT.
Write SVG into PDF is not supported by any PDF libraries. We should use a third part library to handle SVG image. What I use is Batik. 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.
