Q3 is upon us, and so is the release of iText 7 Core 7.2.3! The big news this time round is naturally the official release of our reference implementation of iText 7 for Android, though there’s plenty more that’s new in Core. We have a fix relating to XMP metadata in PDF/A documents, improved support for SVG image dimensions using exponent notation, and revised the way PDF streams with indirect references are flushed.

Plus, we have the usual round of bugfixes and miscellaneous improvements as always.

In other news, a big thank you to @carl-di-ortus for submitting a fix for XMP metadata in canonical format causing issues, and thus generating invalid namespace attributes in PDF/A documents. We determined the reported issue was caused by the XML library used by the .NET version of iText 7 not supporting the 0x1F char, however the fix should prevent such XMP metadata causing similar compliance issues when generating PDF/A documents.

In addition, another pull request inspired us to make some improvements to the way PDF streams with indirect references are flushed. Thank you @LingMan!

In other news for Core, we’ve made some more SVG improvements by adding support for exponent notation using the capital E to specify image dimensions. We’ve prepared a code example to demonstrate this which you can find linked below.

There’s also a nice change for our AGPL users. If a license file is not provided for Core, it assumes AGPL usage and so occasionally a message is printed to stdout as a reminder. However, if you’re happy that you’re in compliance with the AGPL requirements then seeing this message might become a little annoying after a while. If this is the case, you’ll be pleased to learn that you can disable it, see the example linked below to learn more.

  • Save XMP metadata in canonical format for PDF/A documents
