飞碟 - HTML到PDF和许可（iText）

Question

I'm writing code to convert HTML to PDF, which includes the following 2 dependencies:

    <dependency>
        <groupId>org.xhtmlrenderer</groupId>
        <artifactId>flying-saucer-core</artifactId>
        <version>9.1.6</version>
        <scope>compile</scope>
    </dependency>
    <dependency>
        <groupId>org.xhtmlrenderer</groupId>
        <artifactId>flying-saucer-pdf-itext5</artifactId>
        <version>9.1.6</version>
        <scope>compile</scope>
    </dependency>

I have it working. And the only way I can see to do this is using the ITextRenderer . Unfortunately, it looks like this is iText 5, which requires AGPL license, or paying a large licensing fee.

Seems pretty clear to me, based on this license: https://github.com/flyingsaucerproject/flyingsaucer/blob/master/LICENSE

Is this correct?

Is there any other way to do this that doesn't require iText (or licensed software)?

I've tried Apache PDFBox, but it's so low-level, I'm not sure it would be possible. I know it wouldn't be easy. HTML -> PDF definitely isn't possible.

OpenPDF looked kinda weak.

Any thoughts/suggestions?

This is a somewhat small part of our project (startup), so licensed software isn't the first choice.

Thanks.

As of today, there are three implementations of Flying Saucer available, one of which is OpenPDF.

Quoting from their readme (emphasis mine):

The available artifacts are:

• org.xhtmlrenderer:flying-saucer-core - Core library and Java2D rendering
• org.xhtmlrenderer:flying-saucer-pdf - PDF output using iText 2.x
• org.xhtmlrenderer:flying-saucer-pdf-itext5 - PDF output using iText 5.x
• org.xhtmlrenderer:flying-saucer-pdf-openpdf - PDF output using OpenPDF
• org.xhtmlrenderer:flying-saucer-swt - SWT output
• org.xhtmlrenderer:flying-saucer-log4j - Logging plugin for log4j

iText 2.x has unfixed security bugs. New projects should avoid it.

OpenPDF and Flying Saucer itself are both licensed under LGPL. So you can use flying-saucer-pdf-openpdf now to avoid security issues with iText 2 and licensing issues with iText 5.
