How can I render an XFA form? #221

|
I'm trying to render an XFA form, for example the one here from iText: https://github.com/itext/i7js-examples/blob/develop/src/main/resources/pdfs/purchase_order.pdf With the default installation of pypdfium2, the XFA form is not rendered and the image below is rendered: Does the pdfium library that is shipped with pypdfium2 include XFA (and therefore V8) support? If not, is there a way I can use my own library, like the one from here, which is built with XFA and V8 support? Thank you for any help you can provide! |

Any XFA form still fails to render, which is very strange. Some time ago I built a version of pdfium from source (off Chromium 4128) and its It also seems that, in order to work with XFA forms, one must invoke
I'll try re-building pypdfium2 with pdfium from source, and see if that helps. Thank you! |

@mara004 Thank you so much for following this through to a resolution. Sorry about the typo in the test program. I was on vacation which is why I couldn't respond sooner. |
