JPG sluggish Folio

I was wondering if anyone can offer some insight...

I have a horizontal folio only 2048 x 1536 implemented with 5 items. Each section has 6 pages. In the test initially with a 'live' InDesign document, the folio was very slow when it came to vertically scroll the pages. I thought that this could be a problem of having to load the elements individually, so I exported on every page in high quality jpeg format and re-imported them in the folio. That is how it is currently implemented.

Each jpeg is about 500-700 KB and when I publish to the iPad, the vertical scrolling problem is the same. He stutters / takes 2-3 seconds to load vertical pages. By running tests, I wonder if there is a maximum number of pages that you have in each article. I have two sections currently downloaded and the file for the folio size is only 7 MB. Scrolling has worked when I downloaded the folio with png compression but it inflated the size of the file a little.

Any thoughts would be appreciated!

JPEG is on the slower option that you can select for content ipad high resolution. The JPEG decoder provided by iOS is, ah, pokey. You're much better off the publication in PDF format.

  • You can convert a folio created with jpg to PDF format?

    I want to see pinch and zoom in on some of the pages and it seems that I can't mix the statutes of pdf with png except if 'automatic' knows the difference.

    You have to re-create the articles as a PDF. There is no way to change the format of an article having been created in a folio. You can, however, have a mixture of articles PDF and PNG/JPEG of the same Folio.

  • Folio size

    How do I know what size my folio is earlier than upload them to Apple for approval?

    As Martin says, you can see the size of your folio in the Adobe Content Viewer library when you click the item in the gear button to eliminate the problems. Or, you can view the article .folio files in the temporary folder.

    If your folio seems unusually large, here are a few things to check:

    (1) don't embed you great videos?

    (2) never let you link to a .html file "go" in a superposition of web? For example, if the .html file in your Documents folder (rather than in a subfolder with only the assets used), all files and subfolders in the Documents folder are downloaded.

    (3) for overlays of passthrough as sequences of images and the image pans did you use save for Web to save files in a compressed JPG format?

    (4) for the iPad, have you created folios of 1024 x 768 in PDF format? It is the smallest file size. There is no need to create folios PDF 2048 x 1536 for the iPad from the retina.

  • RESOLUTION OF DPS FOLIO PDF

    Hello

    I followed all the instructions manual Adobe DPS and created PDFs (2048 x 1536, 144ppi) for my iPad folio 3.

    Yet, when I download the folio of the Adobe Viewer, images look at shit, they are shredded, and you can see pixels.

    However when I publish the same folio on the iPad 2 everything seems smooth.

    Can you help me to define the process of good compression for images? (I am exporting from photoshop, save as pdf and then linking to indesign... that should work normally).

    InDesign files any of the folio size, should be 1024 x 768

    and to PDF, which is even more important. My guess is that it is a

    huge folio with regards to the size of the file is.

    2048 x 1536 folios are to be created in PNG or JPG, as "refunds". PDF

    folios are well enough designed to operate at all resolutions using a

    iPad 1 and 2 and 144 for iPads of the retina.

  • "The cover image you selected does not fit this folio." - but should be.

    I get the error message.

    "An error occurred during the loading of an image. The cover image you selected does not fit this folio. There must be no more to 1024px in height and width 768px. »

    Jpg files horizontal and vertical I'm trying to download for coverage are exactly the 1024 x 768 and vice versa. I have tred exporting to different presets and resoluitions and Folio Builder still will not accept them.

    I know I ran this problem before and I have searched for it in this forum thinking it would have been displayed in all but impossible to find aynthing - sorry if I'm double posting.

    I think I realized my problem... I got 96 DPI selected, when it should have been 72. stupid.

  • Uploaded to the producer of folio DSP - what to do next?

    Hi all

    I did an ipad, Iphone format and sizes two folios. She could also have been a size Android. Shouldn't matter.

    I've updated everything to the PSD. Both are listed in the Organizer. All required fields are filled and I can hit the button release.

    So far so good, no errors. When I switch applications "publish", I see a list for my folio iphone and my iPad folio. But that's all.

    The question: what do you do when the folio is produced? Where the app does stuff?

    Also, when I'm in the organizer and open a folio, I do not see the pages, I see only a header that I can drag back.

    Update: OK, I got it. You must use jpg or png format, not pdf. This cannot be selected when you create a folio. The Panel that opens the 'default' format is defined in pdf format. You need to change this. Strange.

    Also, I work with a windows PC. With a paid account of CC.

    Any suggestion is welcome.

    Thanks in advance.

    Dan

    If you use creative cloud you use not of all producer Folio, or do you not use "publish." Inside of InDesign, in the Folio Builder Panel, select your folio and open the context menu and select Create App.

    Note that as a CC customer, you can only build iPad applications. We do not support editing simple apps for the iPhone.

  • switching from JPG to PDF editing images of low resolution

    Hello

    I go from jpg to PDF publication for my folio. Most of the things are great. There are some things that seem to always really crappy, like animations with logos and JPG images from photoshop.

    What can I do to fix? I have to redo them with a higher DPI?

    Some assets will look pixelated on HD devices. Use PPP 108 and also use different means for SD and HD devices. Read more here: http://helpx.adobe.com/digital-publishing-suite/help/creating-multi-rendition-pdf-articles .html #creating_multi_rendition_pdf_articles_for_ios_devices

  • Update Folio format or publish again?

    Hello

    I have published a leaflet with the PDF format.

    It works great on ipad, but it does not on Android.

    the folio is published and public... and some are saled...

    I need to change the format of android in PNG or JPG... like this version I would update the folio and not published it. cause I don't want users to buy twice.

    But it seems to be impossible.

    so... First: is it possible to update a folio and change PDF to JPG format?

    If it is not: if I don't publish and remove the folio, then download and publication it once again with the same product ID, users will have to buy again? or they see the folio to download, but for free?

    Thank you

    Unfortunately, you cannot change the image of the folio format. Delete and re-create it. When you publish the folio, use the same product ID you used in the folio deleted.

  • Share app DPS to the customer (no folio)

    Hello

    I have a problem - when I need to share my application with a customer - but the question I have is that if I share the folio (to view in Adobe Content Viewer) then I can't turn off the option to zoom in on the content of the PDF.

    Unfortuantly, I found that if the zoom is activated (as is standard) and then the effects of overlay produce weird effects when content is expanded. I really like to share my application with clients - but must be able to send a version that cannot be enlarged. I understand that I can publish the app as a png or jpg, but this seems to cause pixelation to the text on an iPad 3 (new iPad).

    Any help on this would be greatly appreciated.

    If you have an enterprise of DPS and an iOS Developer Enterprise License license, you can create signed company built using DPS App Builder to distribute the application directly to your customer.

    If you do not have two of them, you need to add your UDID iPad client and re-create the MP files then rebuild the Viewer to distribute.

  • Help needed - "cannot download the folio on your local drive.

    Hello

    (WARNING: for the first time post :-))

    I have trouble downloading my folio published. During the last 24 hours I repeatedly get the following error (after a long wait with the status 'Preparation content by downloading... ") on different computers (Mac/PC) and browsers:

    An error occurred during the export of the folio

    Could not download the folio on your local drive

    My first version is delivered to an Android app (created using the viewer Builder) and has been incorporated into an iOS app (also created using View Designer).  All this worked without any problems and I can export this now.

    In order to optimize the folio for the new iPad, I decided to use the PDF option that required me to rebuild the folio.  The content is identical to the bar a few dates changed from 2011 to 2012.  I just need to export the folio so I can incorporate into an update iOS application.  The folio is not (at this stage) given to the Android app.

    I hope someone can help :-)

    Edit: Using the new Adobe Content Viewer I see TWO versions of the folio - one with the lightning bolt blue - but maybe that's normal?

    Hi Philippe,.

    Thanks for the reply.  After a lot of testing, I discovered that my preview of the cover images were the problem.  I've been using PNG files and when I used the versions JPG export worked.

    Maybe that's a one-time problem, but I thought I'd share the solution in any case.

    Kind regards

  • using folio producer for the 1st time

    I just created a test application which is only one vertical orientation. But when I try to post I get a message telling me that I need a glimpse at both vertical and horizontal. I used to be able to create a version, has that changed? (It is not a big problem for me because I always create two directions, so I'm just curious)

    see you soon

    Alistair

    When you publish, the tools check to make sure that all required files and fields are specified. The edition is to make publicly available folios. In this case, you click the preview options Horizontal and Vertical preview, then select jpg files.

    You can watch videos or a walk through the tutorials to learn more about the publication process.
