FlowPaper 3.1.1 Release Notes

Sunday 17th September 2017

This release mainly contains smaller corrections and improvements. We’re getting this release out a little earlier than usual due to iOS 11 being released in the next 48h as we found some optimisations we wanted to include prior to this release. We have seen some issues in iOS 11 related to how background images are being loaded and unloaded in the Safari browser and we have made optimisations accordingly. This was mainly affecting the Zine viewer.

 

How to update

You don’t need to republish existing publications to update if you’re mainly interested in the adjustments for iOS 11. You can simply replace the existing “FlowPaperViewer.js” file in the js/ directory of any publication or installation you have created with the new version. You can grab the minified version of FlowPaperViewer.js here.

How to correct the reading order in PDF documents automatically

Thursday 31st August 2017

You may have noticed that the text selection can behave erratic when selecting text in your PDF reader (such as Adobe Reader). This is because text in a PDF document is not necessarily ordered in logical reading order. You can see an example of this behaviour in Figure 1.

Figure 1

So why is this a problem? It’s a problem because of two reasons; firstly, it means that Google will most likely index text in your document in the incorrect order. Sentences are in some cases broken and as a result you may not be getting the search hits you’re after for your content.

The second problem is that people who use screen readers won’t be able to read the documents properly. Text will most likely be read out in the wrong order.

 

Fixing the reading order automatically

The typical solution when dealing with reading order problems is to use something called PDF tagging. This requires you to go through the entire document and tag each text and mark which text that should follow that text in reading order.

Using machine learning, FlowPaper is able to reconstruct the logical reading order of your documents without any manual tagging work. Single column layouts, multiple column layouts, you name it. FlowPaper does this by analysing the layout of the page very much in similar ways as the human eye is recognising a page and its reading order.

 

How to fix the reading order of your PDF

Make sure you have the desktop publisher installed. It can be downloaded from our public download page.

Figure 2
  1. Firstly, Start up the desktop publisher and select the “Elements – Slide” viewer in the top right corner as seen  in Figure 2
  2. Make sure the “Improved Accessibility” checkbox is ticked in the “Accessibility & SEO” section
  3. You can now go ahead and import your PDF. Make your desired adjustments to style and click “Publish” in the top.

 

Verifying the Results

So how can we check that the corrected reading order is correct?

You could let a screen reader read it out if you have one installed. You can also check the text order manually if you know your way around Chrome a little bit.

  1. To use Chrome to check that the elements are in the correct order, open the publication in Chrome using “View Offline Version” from the desktop publisher and open up the Chrome dev tools from the View->Developer->Developer tools menu
  2. What you will see now is all the HTML5 elements that the desktop publisher has created when converting your PDF document. An easy way to check the reading order is just to step through the elements like in the animation below.

 

Voila! Please let us know if you have any questions regarding reading order or how it can be used in other scenarios!

Next release will be at end of July/beginning of August

Monday 19th June 2017

We’re in the process of implementing new machine learning (AI) algorithms for our desktop publisher which we hope will help a lot in creating responsive publications from PDF documents. The results we’re seeing so far are very encouraging. We have been working hard on getting these in place since the start of the year under the hood and had a big breakthrough in late April when we took a new approach on how documents can be republished using unsupervised and supervised algorithms.

As we’re in the midst of this we have decided to delay next release until end of July or beginning of August. If you are waiting for something you have reported to be fixed and would like a pre-release then you are welcome to flick us an email and we’ll help you out.

All the best
