IBook Author (pictures/images)

On the iPad, how can I stretch either an image or picture to be the full size of the iPad screen?

Add it the full size of the screen. 1024 x 768 / Portrait

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:

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?

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?

Importing full-page images into iBooks Author (without image degradation)

Hi ,, I have had little success importing images created with paint programs such as Corel Sketchpad, Photoshop, Corel Painter, etc. Everything seems to work just fine, but there are pixelated artifacts in the final image that shows on the iPad. I create the orginal images at 1024 x 768 ... and save them as high-qulaity jpgs and pngs .... but still poor qualiting especially where large blocks of solid colors are adjacent to one another.
When I use a vector program such as Flash or Illustrator and export those images as jpgs ... they look perfect on my iPad. I don't want to use a vector program however ... I want to use paint programs.
Anyway have success with paint program images? If so, what is your step-by-step process? Hopefully Apple will fix this bug so that paint program's exported jpgs don't have pixelated artifacts at edge areas. There is also a very noticeable color shift in the imported image .. much ligher and less saturated colors.
In the image below you can see the imported image showing artifacts and the orignal image is not showing artifacts.
Thanks, Frank

An iPad 2 screen is 132 - new ipad is 264.
In cases where you're seeing noticable degradation I wouldn't work with less than 132.
Start high and reduce....don't try to make low do something it can't by simply adjusting the resolution up.
I tend to avoid those 'paint programs' And remember, this isn't just about iBooks Author....iOS does the heavy lifting, but sure, it can only do as good as iBA spits out. I think they're working to trim the sails on compression etc. and it will only get better over time.
The @2x scheme is working well for iOS - I have some stunning graphics for the new iPad in my latest app.
Good luck.

IBooks Author ( interactive image )

Hi to everyone,
I have a problem with an interactive image in iBooks Author. i've added the image in .jpg format and all the interactive "buttons" with own interactivity zoom for each one. When I test it on the working area, it works correctly even it's quite slow, but once I preview it on mac book pro or ipad, it doesn't work as shown in the working area. when i click on bottom to see the details, it becomes white. Who can help me?
Thanks
Alberto

Have you solved your issue? If not, can you provide us with some screen shots of what it looks like in iBooks author and as preview in iBooks on your mac?

Widgets using ibook author - centering images when resizing

When I drag and drop png files into my ibook author widgets and attempt to zoom out to the maximum, the top portion of the image gets cut off. What am I doing wrong?

You need to click on the edit mask button until a little grab hand icon appears( may have to click a few times)
with this hand you can click on the image and drag it around with in the frame (croping it however you want)
ie drag it down so top of image shows
Images should be at the resoultion the are going to display at.
they should be scaled/croped in photoshop etc befor bringing into IBA.

IBook author interactive image label: graphic control is locked?

The interactive image lets you adjust the frame and background, but not the labels nor end the point styles! The ability is there but it is locked! Here's a screen shot showing the 'greyed out' control options. Is there a trick to enable the capability? Or is it on the debug list for the next update?

Hello Vita,
When I was last working with this widget and came across the same issue.
The only way to try and control it was by adding in character returns to change the height and to stretch the box out by the handles at the left and right of the box itself. But yes it would be great to have more control over the the parameters.
Regards,
Nigel

How to copy/paste texts/images from webpages in iBooks Author?

Hi,
I want to copy/paste text/image contents from webpages with iBooks Author, somehow images can't be copied, only texts can be copied with copy/paste editing. Wonder if there are any ways to include images with simple copy/paste?
Tried to search iBooks Author help, could not find answers. Please help.
Thanks

Perhaps the people who spent a lot of time and money to produce the websites.....and who own copyright ...don't want anybody using their work without payment or credits. Have you contacted the websites owners to ask permission?
IF any person(s) use anything from websites without permission apart from being to lazy to email to request permission....could face a legal action if and when the sites owners fins out.
There is another her misconception that "free" websites and content on "social media" such as the dreaded FaceBook....can be used without consequence. Almost all "free" websites are common licence material - which requires permission and those who give permission do so only for personal or none profit reproduction.
i Use a blocking script on my websites which apart from preventing a right click...those who try are whisked off my website to the the UK copyright website page which explains my rights!
You may wish to check out your iBooks contract with Apple and read their warnings on use of others copyright material.
You could ..and should contact the websites...explain what you want to use and why....and ask them if they can supply media.

Can't drag image into widgets using ibooks author

i have ibooks author 2.0 and i'm running on 10.8.2. i was working on ibooks author and suddenly i couldn't drag any pictures into the widgets, not the Interactive Image, not the Gallery. In the Gallery widget i could get around it by manually inserting pictures (tediously) using the inspector, but there's no option for that using the Interactive Image widget. i've restarted the computer, hasn't made any difference, any help would be appreciated, thanks

yes, it goes onto the page, but it won't go inside the widgets. i've also tried deleting and re-installing ibooks author and it hasn't resolved the issue

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...

Image swipe on iBooks without the use of iBooks Author

Im working on an e-book using calibre and dreamW. It contains lots of pictures. What i want to do is tap on one picture, make it pop at you (make it larger, just like it does when you tap on an image) but then from that be able to swipe to the next image, swipe back and so on. I manage to use JavaScript and make it happen in html, but not in xhtml...
So i would really like to know before going any further, Is this action possible for iBooks without the use of ibooks Author?? in other words: Does iBooks allow the swiping gesture to see images within the normal swiping of the page
Any thoughts, ideas? thanks!

If you're looking to trap the swipe gesture and take some custom action with it, yes, it's easily doable within a hand-coded ePub and iBooks. We do it in our books to suppress the normal page turn response on certain controls. Trap the move event, act on it, and preventdefault.

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.

What is the best resolution for adding and viewing pictures/images in ibooks?

I'm trying to add pictures/images and I was wondering what the best resolution is for viewing? Any help would be great.

iBook Author seems to scale the images automagically during the book generation, so targeting iPad's native resolution should be fine.
Havign said that, I'm currently creating art based on the assumption the next generation of the device will have double resolution screen, so a photograph should be scaled to 2048x1536 pixels if you want it to be full screen at 1:1 pixel mapping.
If you're creating widgets, the art (probably) won't be scaled, and you'll need to use the pixel dimensions you want the art to appear on screen.

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.
Moe

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.
