Ibooks author image size

Hello ibooks author new users,
Any idea about the "good size" for a picture or photo in order to create a not too heavy ibook?
I am working on a new edition of a 19e century old book in French.
More than 20 chapters + 1 different picture for the first page of each chapter + 15 to 20 interactive images (old maps + engraving) within the book = 100 Mo for the book already... So it is scary or attractive ?
What about the other books already in store? Any limit?
Any "specialist" or studio around able to improve and to lighten my work at the end?
Thanks for your help.
Frederic

You can look at other books already in the store to give you a perspective how they act and feel.
Know that the max book size is 2GB. Also know that anything over 20mb must be downloaded via Wi-Fi or docked connection.
Create a sample, load it to a device and test drive...

IBooks Author Page Size Question

I would like to use iBooks Author to put together a book for print (instead of using InDesign which is not intuitive for photo placement). iBooks Author looks good and the templates seem to work very well, but I have found no way to specify total page size dimensions - specifically A4 (210 × 297 mm) in portrait orientation.
Also the PDF export - which I should be able to use for printing - has strange lines around the overall graphics (indicating larger actual document size?), and has a big watermark at the bottom reading "iBooks Author," which wouldn't be good for printing.
Can anyone give me instructions as to how I can:
1) Specify page spread dimensions for the whole document (except for the cover which I will design separately)?
2) Export to PDF in proper printing format without faulty document dimensions or watermarks?

esagustin013,
Indesign as well as Quark are still the mainstream layout tools fore creating Print collateral...as of the latest versions of InDesign and Quark...both are beginning to introduce ebook production.
As for your last sentence, it is not true that both are beginning to introduce eBook production. Adobe InDesign has been doing that for a couple of years, along with PDF technology. Now it even gets much better and, it is true that it is getting more powerful. It is not recommended for novices to use these apps, so iBooks Author app is a very nice simpe app especially designed for iPad platform.
I would highly suggest you search for a tutorial pertaining to how to place images into indesign and how to minipulate them with your text boxes. Far more power in these programs...completely tailored for Print.
Again, last sentence, it is not true that it was completely tailored for Print production. Adobe InDesign app is a totally different app now than it was once developed for at the time when Adobe first released InDesign 1.0 some years ago. I can't believe how time flew from 1.0 to now CS5.5. However, you are correct it is very powerful professional layout app for print and even eBook production and even ePUB production and all. And even PDF files for web. Even it works just fine in iPad opening PDF files.
I am intrigued by iBooks Author is capable of making more interactive iPad iBook textbooks.
I am interested about what Adobe have to say about iBooks Author app. I wonder if Apple eventually develop professional-grade layout app - more powerful than that of iBooks Author or iWorks app. I guess we'll wait and see. Probably not.

How do I find iBooks author file size? want to stay under 1gb.

I am wondering if there is anything like Get Info for the iOS. May be obvious but I have not found it. TIA.

Share/export as .ibooks file to where you can find it - then locate it in the Finder - Use the menu Get Info it is't now shown in the Finder window.
You can also load it to iTunes and do a get info there as well.

Ibooks author file not accepted by itunes producer

I have completed a book with an Ibooks author file size of 830MB; it is not being accepted by itunes Producer for upload. Do I need to export it to IBooks format? I did this export but the resulting file is just 77MB. I did not try to upload it via Itunes Producer as it seems to small to be correct. ????????

Thanks this helped but not enough. I was trying to feed the I books author file directly. So, i went to File/publish and created a file labeled ITMSP. Then went back to the Publisher wizard. I was unable to load the ITMSP file but the Publication window in ITUNES Producer has the Ibook file I exported from IBA in it. I continued through the wizzard but chose not enter a target audience. When I got to the end and clicked on the button to send to Apple it went through a verification process and flagged the lack of target audience. So I went back and entered 13 and up. But the same error keeps occuring and I can not proceed. Any ideas on the following
1. How I clear the error message now that I have entered the right data
2.Is the Ibooks export the file that should show in the produce window, or should it be the ITMSP file that wont load there?

Image size for ibooks author

Hi
I am making a book using iBooks author. It will be image heavy. (40-50 images)
I have a few question on images.
1. I do not want the file to be huge or take an age to download so an Apple rep informed me that the images should ideally be no more than 500-600kb per image saved at 72dpi
Forgve my ignorance but can someone eplain to me what this means in terms of pixels? What size (height and width) and resolution (pixels per inch) should I save images so that they can be seen at their best but not be overly large?
The finder window when I try to resize images gives me some standard options. Should I take these? Also if I click on 1024 x 768 pixels as a standard size, the width and height boxes do not change.
I'm a little confused.
Many thanks

This thread is over 12 months old now...perhaps you posted here by mistake. Your problems have slready had rep,ies in another thread, however to answer your question..
No, iBA does not seem to change image size....which is why you see posts about tickets for images size in books held back by the review team.
Consider that Apple gave you free use of iBA. Pages, inDesign and others come at a cost.
If you intend to create other books with a high photo image content, you really need to consider investing in suitable software.
I suggest you search the net for "photo image editors" or similar, dont wait for iBA updates..I doubt Apple will address image sizing and "cropping" can effectively be done using the image mask.
As in all projects be it eBooks, making kitchen tables or building a tree house...its sensible to gather all your assets and ensure they are suitable for the planned use....before starting the construction process.

Searching for original image size of jpgs inserted into iBooks Author.

Does it matter or does iBooks filter and change the jpg within program after inserted? Does the jpg become part of the iBooks Author file or read the original jpg until collected for publishing?
I'm creating a full-page layout with images for a children's style book. The jpgs insert small and I've been dragging each one to fill the page. Look great on my MacBook Pro but don't know how they translate into iPad as I don't own one. The jpgs' outer boundaries cross onto the next page to fit as I want it too.
If I knew the exact size of the iBooks Author page and the pixels allowed, I could crop in photoshop and insert it meeting the dimensions. Can't find dimensions of the page size in all my reading.
Thank you!

You should size/crop outside and then bring in...

Re: Exact page size?

Size & scale images before import or let iBooks Author do it?

I'm importing images into iBooks Author and wondering if I should size them and compress them to roughly the size I need them on the page thus redicing their file size. Or go with the highest resolution and quality and just let iBooks Author compress and scale the pictures. Wonder also what gets the best result.
Is there any benefit to importing high resolution TIF or highest quality JPEGs???
Any help, thoughs, tips appreciated.

Open the Help files and check the section dealing with Graphics.
Better, if you have an iTunes Connect ( if not get one you will need it) account you should open it look for Deliver your Content, top right are a group of PDFs download them.
One is the Asset guide - which give full info about graphics. Including.. Tiff is not acceptable.
Maximum image file size is 3.2 megabyte. For iPad retina ( and basically everything) 2048 x 1536 rsolution is of choice really, subject to the file size and the books size max of 2 gig. Unless all your images are intended for full screen, re-size to suit your layout.
iBA does not compress or scale anything.. thats your job.. and if you get it wrong.. the book will be rejected by the preview team until you sort it out.
Save yourself work and time, download and study the asset guide and the help files.

How can I create an iBook using iBooks Author using images from a PDF?

I have a complex book with custom fonts and lots of images, and the client wants it on the iPad. So my most reasonable option seems to be to take images from a PDF and use them for the pages. However, images in iBook Author don't get "laid out" as expected in Portrait mode. How can I create a layout that is essentially one image per page in portrait mode, and then convert that to landscape mode? Or is there an easier way to go about this?

tk0us wrote:
Make sure you have disabled portrait in the Inspector.
I don't understand why portrait mode defaults images and other "widgets" to thumbnails. The original format of the book (and of 99% of all books I'm guessing) is in portrait format. By forcing the book to work only in landscape mode it's forcing the page image to be half the size, and that makes using this book particularly difficult. Is there no way to force the pages to be full-size in portrait mode?

On Ibooks Author, my programmed image for the Chapter page no longer shows up on new pages, just appears as a question mark inside a box, How do I fix this?

On Ibooks Author, my programmed image for the Chapter page no longer shows up on new pages, just appears as a question mark inside a box, How do I fix this? Please help, its the same when I try and copy and paste the same image within Ibooks author.

You may have moved or removed content on your page or its possible you used the"Adjust Image" and over sharpeed one or more images.
I assume you mean it does not show up of new Chapter pages... have you checked the template?
Where you see the ? you need to either reduce teh box outline size - or drop anther copy of the original image onto it, it may fill the ? box or sit on top.... delete the ? box.
If its Chapter page only related, its better doing this in the template.
Is you image .jpg or .png?

What is the best kind of images should we use in iBook Author?

We are using a png image in a keynote inside our iBook.
But we are loosing the quality of the image when we reduce the box size of the keynote.
Is png the best kind of images for a keynote in iBook Author? Is there a better kind of image to use?
For example, we are using a png image in a Pop-Over widget, and it is perfectly clear.
But if we use the same image in the first slide of a keynote, the image showed in the iBook is not as clear.

Basically jpg for digital photos and png for everything else.

IBooks Author changed placed video size on it's own. Anyone else have this happen?

I'm creating a rather large ebook with iBooks Author (2.1.1) on Mac OS 10.9.2 (mavericks) . Currently over 350 pages typset. Was final proofing and ran into a font conflict over the weekend (Palatino was substituting), which miraculously resolved itself when I ran typical Mac diagnostics (so maybe a font got corrupted or something). So I was celebrating my victory when I noticed that randomly, a number of placed videos had changed size
I noticed because I purposefully set all video preview images at 285x214. I've found at least six that changed to 200 x 150 (which possibly is the default when you create a new video).
I just find it curious that this would happen for the first time, after I've been working on this book since last November (so about 6 months)
I did upgrade to Mavericks April 15th. But I was working on the book last Saturday and these issues did not show up. Took Sunday off. Then mid-day Monday, I started noticing the font issue. Then this morning noticed the resized videos.
This is what it changed it to:
This is how i originally designed it:
Of course, the change in size made the text reflow throughout the chapter. So now I'm going back page by page from the beginning to see if this annomoly only happened in this chapter or throughout the book. It didn't affect every placed video — only some.

Is there a way for you to disable the firewall and your anti-virus software? That should help.

Using keynote in ibooks author do you set slide size to 2048x1536

For my second book I want to use the keynote widgit. If I set the slide size to 2048x1536 will that be ok for the ipad 2 and origanal ipad in addition to the new ipad? Also, when you initially bring an image (jpg) into keynote that will eventually be for import into ibooks author should it be resized to 2048x1536 just as we do when bringing one directly into ibooks author. I am using keynote 5.1.1.

Why does ibooks author automatically resize all images of a gallery?

The point here is, I have more than one graphic files (not pictures taken by a camera) to put into one gallery widget of an iBooks Author document. Unfortunately, not all figures have the same height/width aspect ratio. If I put them together in the gallery, some of them have cropped widths others have cropped heights. Impossible to losslessly fit all into the same gallery. If I scale alle figures to the same width, the result is acceptable for the figure with the highest heigth, all other figures are cropped again.
Well in a first time, I was not that much concerned, but the iBooks Author Quality check refused to publish such eBooks, where some picutes appear cropped in the small view (not in the full-screen view).
Now, why is the iBA software automatically sizing all images of a gallery w.r.t. the center of an image? It would be of much more help, to leave some white background boarders on images of un-equal height, as long as the width of all images is exactly the same. The crop-pan function would then be useful to individually place a smaller-than-the-rest image in that frame of its larger precedecor image.
Can this autosize function be turned off? Am I really forced to paste smaller images into a white image of the maximum height/width of the galery's largest image?

If you have differently shaped (height/width) images that you want to place in one gallery....
The first image you place will determine the shape (max height and width) of your gallery mask, so choose it wisely.
Before you add each image to the gallery go to photoshop and:
1. Size the IMAGE to be at the max height OR width of your gallery mask -- do this if you want at least one dimension (height or width) to fit all the way across or up and down in the gallery mask.
2. Size the CANVAS to the same height and width of your first image (the size of your gallery mask).
I hope this makes sense and is helpful. Yes, it's ridiculous, but it's the only way I found to make images of different dimensions fit in a gallery.

IBook Author of the video size

I would like to know what's best way to set up iBook Author of the video size and format file for all ipad devices including ipad air.
I already knew about this part:
   •    To create up to a 420p movie: Select “iPod touch & iPhone 3GS.”
   •    To create up to a 720p movie: Select “iPad, iPhone 4 & Apple TV.”
   •    The numbers refer to the number of vertical lines. For the best quality, select the 720p (iPad) option
I wonder if I can set up the aspect ratios like 4:3 frame (small video of box with story) in iBook Author for ipad air to be able to see this on full screen from iBook shelf. I have ipad and ipad mini but I don't have ipad air. I wonder if it will have good quality video like 4:3 ratio for ipad air screen with Retina display? Since Apple support didn't provide enough details how the overall video would look like on screen without stretching or using proper proportions.
Thanks,
Alfredo

If you create a 1024x768 video, you will be making the fullest possible use of screen real estate on a non-retina iPad (no letter boxing or pillars needed). Double that to 2048x1536 for retina.
Having said that, I should point out that the dynamic duo of iOS and the iPad;s video firmware provide some of the best scaling routines I have seen. So 1024x768 video on a retina iPad will look just fine. With moving pictures, high resolution doesn't return as much benefit as it does with static images.
It would be interesting to see what the video optimizer in iBooks Author does with 2048x1536 video. To find out, we'll need to use iBooks Author to create project file that includes a 2048x1537 video and then export as *ibooks and deconstruct that *.ibooks file.

PNG-8, PNG-24, or does IBooks Author optimize images?

We have a fairly large reference book that is being converted to IBooks Author. The book contains hundreds of line art drawing that are being colored. Because of the large amount of drawings we are considering using PNG-8 format, but for some reason in the back of my mind I thought IBooks Author used PNG-24 only.
Does IBooks Author optimize images?
We are using Photoshop “Save for Web” feature to save the files. Dimensions are 2048 x 1536.
Here is the file size of 3 PNG-8 files: 42k, 58k, 55k
Here is the file size of the same 3 PNG-24 files: 71k, 102k, 99k
The colors and quality seems to stay the same. Can anyone see any “gotchas” before I continue? Hate to add hundreds of PNG-8 files only to need to replace them later.
Thanks,
Rhek

Drilling down into an exported .ibooks file, shows info an example png as follows:
Color Model: RGB
Depth: 8
DPI Height: 72
DPI Width: 72
