![]() The PhantomJS was also discontinued since Mar 2018.īesides, I could not use PDFBox to embed fonts fully either. I couldn’t do anything here because PhantomJS used a very old version of Qt (only Qt v5.x onwards supported PDA/A). ![]() This did not comply with the PDF/A specification. The library always embedded the fonts using Subsetting (meaning only the characters were used in the document were embedded). My project used node-html-pdf which in turn used PhantomJS to render HTML into PDF. I could not successfully generate PDF/A document by converting the existing normal PDFs generated from Meteor because the PDF generated did not embedded the font fully. But, I have really got stuck at part 1 for a long time.Įventually, I found the root cause by delving deeper into source code of some libraries PDFBox, PDFBox Preflight, node-html-pdf, PhantomJS, etc. With filling some mandatory information, I passed the parts 2 and 3 successfully. Automation tests: writing unit tests with using PDFBox Preflight as here.Acrobat Reader: opening a file, I could see the document properties.I used these following tools to verify the result: But my templates were built on HTML, CSS and Meteor and data was bound dynamically.īasing on the example of creating PDF/A here, I tried to convert an existing normal PDF file into another PDF/A. There seemed to be no tools for converting from HTML, CSS into XSL-FO.Due to limitation of formatting support, it’s hard to format content of a PDF if its template is complex such as including images, tables, etc.Apache FOP strictly required to provide templates with XSL-FO format which is not supported wisely. I needed to know the specification of PDF/A compliance, and to build my own lib for generating PDF/A documents.īasing on these insights, I decided to go with approach (2). Forking a open source project/building my own PDF/A generating engine It looked promising that I could convert a normal PDF document to PDF/A one. I needed to defined the templates by its own ways (FOP files) instead of HTML and CSS. I tried to contact them to know the price but they requested me some information even I could not estimate to answer it. Several approaches for creating a PDF/A documentĪt the first glance, I found some approaches as follows: For example, no executable file launches are allowed or no external content references are allowed. The fonts of document’s content will always be displayed the same on all places, not depending on any devices.In my point of view, it’s a standard file for archiving thanks to key features: The ISO requirements for PDF/A file viewers include color management guidelines, support for embedded fonts, and a user interface for reading embedded annotations. ![]() PDF/A differs from PDF by prohibiting features unsuitable for long-term archiving, such as font linking (as opposed to font embedding) and encryption. Dig through the forums for more info.PDF/A is an ISO-standardized version of the Portable Document Format (PDF) specialized for use in the archiving and long-term preservation of electronic documents. If you are running into any problems, please make sure you are stopping your displays and not letting them persist (which is what happens if display.stop() doesn't get executed).
