Memory Handling in DPS

If DPS articles include memory-intensive overlays, you might run into trouble when viewing them on mobile device with obvious memory limitations. Sometimes the app becomes sluggish, sometimes it crashes, and sometimes it takes a PDF article too long to load.

How do you avoid these memory problems? If you go against guidance and do something like create a pan and zoom image with a 5000×5000-pixel PNG image or scale down a huge video, you’ll likely crash your app. However, in some cases, individual overlays that by themselves wouldn’t cause memory problems can be a problem when combined with other memory-intensive overlays on the same page or even on adjacent pages.

Whenever you turn to a page in an article, the DPS viewer loads each page above and below that article into memory, and it loads the current page of the next or previous article. This pre-loading improves the performance of articles and helps prevent crashing when users swipe quickly.

In this example, viewing page 2 of the third article loads the pages above and below it as well as the first page of the articles before and after.

How to Submit DPS Apps to the Gallery

The Digital Publishing Suite Gallery is a great place to check out apps created with DPS tools. Apps used to be added to the gallery through an obscure option in the DPS App Builder that’s no longer available. To add your DPS app to the gallery, take a couple minutes to fill out a form.

First Folio Free and Digital Blow-ins

Publishers want to use many of the same techniques for digital magazine publishing that they use in their print magazines. With the v25 release, both Professional and Enterprise publishers can take advantage of a few new features that help them market their magazine more effectively.

First, take a look at Colin’s video. Then come back and read the rest of this article for additional details.

First Folio Free

Here’s a common experience. Someone wants to check out the new magazine on their iPad, so she downloads the free app from the App Store full of anticipation. When she opens the app, she doesn’t see any content–just a library with issues for sale. So she gives the app a poor rating, deletes it, and goes back to play another level of Angry Birds.

With First Folio Free, publishers can now select an option in the Account Administration tool that entitles the most recently published retail folio to first-time users of an app. That way, when users download the app from the App Store, the most current issue can start downloading, providing a better initial experience for some publications.

Select this option in the Account Admin tool to enable First Folio Free. [Click image to enlarge.]

DPS Tips HTML5 Examples

In DPS Tips, I included several HTML examples that are used in Web Content overlays. I’ll attach the source files for these effects.

NOTE: Several people have reported to me that they cannot download the .zip files. I’m looking into this.

Scratch Off

Let’s start with the scratch-off effect example.


Download (as used in DPS Tips)

Download (no extra text or borders)

  1. Create two images the same size.
  2. Name them “foreimage.jpg” and “backimage.jpg.”
  3. Unzip the file, and replace the foreimage.jpg and backimage.jpg with your images.
  4. Rename the scratch_off_v.html file, if necessary. Change the suffix to _h for horizontal-only folios or remove the suffix for dual-orientation folios.
  5. Create a Web Content overlay the same size as your images.

Viewing DPS Tips on a Computer

In the DPS forum, people frequently answer questions by pointing to the such-and-such article in DPS Tips to see an example and steps. In response, several people have mentioned that they don’t always have access to an iPad or other device to view DPS Tips. You don’t need an iPad. If you know where to look, you can view all the DPS Tips articles on a computer.

I used the social sharing feature to make all of the folios available in most computer browsers. If you click the following links from an iPad, you’ll jump to the first article of the issue in the DPS Tips app. Click any of these links on a desktop or laptop computer (or a new Surface tablet), and you’ll see a “Web Viewer” version of the articles in each issue.

In Web Viewer, click the icon in the lower left corner to switch to a different orientation. Click the icons in the bottom center to view different articles. Click the icons in the lower right corner to view different pages in the article.

Note that not all features are available in Web Viewer. For example, panoramas are not yet supported. You’re better off using DPS Tips on an iPad or another mobile device, but if you’re away from your iPad, use these links.


DPS Health Status Page

The new DPS Status page shows ongoing issues with DPS servers as well as planned maintenance. If you’re a DPS publisher, you’ll want to bookmark this page or opt in to receive email notifications. If you know you’re going to publish your new issue at a specific date and time, you’ll want to check the DPS status page to see if maintenance is planned for that time period.

If you wish to receive email notifications when the Adobe DPS team updates the DPS Status page, go to the DPS Status page and specify your contact information in the “Receive Updates” section.


Again, here’s the DPS Status page.


DPS Sections

The Sections feature is new with the v24 release. This feature is primarily intended for newspaper publishers who want to allow their customers to download only specific sections of a folio, such as Entertainment, Sports, News, and Lifestyle.

How do you create Sections?

Simple. Go into the Folio Producer Organizer and open a folio in the Folio Producer Editor. Specify a section name for each article. Make sure that you specify the same section name for at least two articles. Section names are case sensitive, so take care when adding values. Copy/paste is a good idea.

If you don’t specify a section name for an article, that article gets downloaded when any other section is downloaded. You might want to leave the section name blank for articles such as covers and tables of contents.

Specify section names in the Folio Producer Editor. (Click to view larger image.)

You can also use the sidecar.xml file to specify section names for articles in a folio.

Once you specify sections for the folio, you need a v24.1 or later viewer to see the sections.

Creating DPS Folios for Android Devices

This article used to contain a bunch of complicated information about various options for targeting the various Android models. However, now that the native Android viewer is available, the following articles are better resources:

Structuring Files for DPS

If you’re using the Adobe Digital Publishing Suite to create apps for mobile devices such as the iPad and Kindle Fire, it’s important to structure your source files appropriately. There are two main reasons for structuring files appropriately:

  • To import articles, re-create folios, or create folio renditions for multiple devices.
  • To transfer files from one computer to another.
