IBooks Author Scale and Rotate in preview

I just started with iBooks Author. I made a simple book with several chapters and pages. When previewing the book in the iPad the pages zoom and rotate with a two finger gesture. Then snap bak to the default scale and rotation. Imagine trying to pinch to zoom, but having the page scale.
How can make the pages use the standard zooming behavior with out rotating and hold the zoom without snapping back to the initial scle?

Sorry about that. I haven't used that software before, but they appeared to fit the bill according to their descriptions.
There is another program, Image Tricks, that is for Tiger and it will let you rotate images and save the changes.

I can't find any hacks for Preview that will let you do what you want.

JS CS3 flag duplicate images with scale and rotation differnce

I've been trying to cut down on the number of images a script I have would produce. The old script would look for links that are being used multiple times and then just version the link which is fine. What I am finding this that although a document may have one image linked 9 time 6 times out of the nine the image is scaled and rotated the same amount and the other 3 times the rotation and scaling also match. In this example the image only needs 2 versions the first as the original and the second with the scale and rotation of the image used 3 time let say.
So to the code:
The following code will work through the doc and create an array of the links as duplicates:
function LinkUsage(myLink) {
    var myLinkCounter = 0;
        for (var myCounter = 0; myCounter < myDoc.links.length; myCounter++) {
        if (myLink.filePath == myDoc.links[myCounter].filePath) {
            myLinkCounter++;
    return myLinkCounter
var myDoc = app.activeDocument;var myNumLinks = [];
for ( var t = myDoc.links.length-1; t >= 0; t-- ){
    if(LinkUsage(myDoc.links[t])>1){
            myNumLinks.push(myDoc.links[t].id);
Is there a way to loop through the array and only flag the differnent scale and roatations. What I should get is that out of the multiple link uasage the image is only changed twice out of the 9 times used.
I was trying to loop through the array and then loop through it within the loop to compare the link but this does not work for obvious reasons.
for (var i=0 ; i <myNumLinks.length; i++){
    var valLink = myDoc.links.itemByID( myNumLinks[i]);
        if(valLink.parent.constructor.name == "Image"){
            for (var j=0 ; j<myNumLinks.length; j++){
                if(myDoc.links.itemByID( myNumLinks[j]).parent.constructor.name == "Image"){
                    if(valLink.parent.parent.images[0].rotationAngle != myDoc.links.itemByID( myNumLinks[j]).parent.parent.images[0].rotationAngle){
                        $.write(myNumLinks[i]+"\n");
Is what I am trying to do possible and if so any suggestions would be appreciated.
Cheers, John.

I think I might be one step closer to getting this to work. I've been able to just capture the file path of the duplicates using:
//count the number of times the link is used
function LinkUsage(myLink) {
    var myLinkCounter = 0;
        for (var myCounter = 0; myCounter < myDoc.links.length; myCounter++) {
        if (myLink.filePath == myDoc.links[myCounter].filePath) {
            myLinkCounter++;
    return myLinkCounter
//check if the filepath has been added to the array
function chkVal(val){
    var compCount = 0;
    for(var arr = 0; arr < myNumLinks.length; arr++){
        if(val == myNumLinks[arr] ){
        compCount++;
    if(compCount >=1){
        return false;
        }else{
            return true;
//check the links inthe doc
var myDoc = app.activeDocument;
var myNumLinks = [];
for ( var t = myDoc.links.length-1; t >= 0; t-- ){
    if(LinkUsage(myDoc.links[t])>1){
        if(myNumLinks == 0){
            myNumLinks.push(myDoc.links[t].filePath);
            }else{
                if(chkVal(myDoc.links[t].filePath)){
                    myNumLinks.push(myDoc.links[t].filePath);
for (var i=0 ; i <myNumLinks.length; i++){
    $.write(myNumLinks[i]+"\n");

Scale and rotate a tiff image

How do you scale and rotate a tiff image without running out of memory?
I have been trying to scale the image and rotate it before i pass it to the DisplayJAI but i keep running out of memory.
code i use to rotate the image.
private Image rotateImage(boolean rotateRight)
Image img = imageHolder.getInUseImageIcon().getImage();
Image rot = null;
int imageWidth = imageHolder.getInUseImageIcon().getIconWidth();
int imageHeight = imageHolder.getInUseImageIcon().getIconHeight();
int buffer[] = new int[imageWidth * imageHeight];
int rotate[] = new int[imageWidth * imageHeight];
try
MediaTracker tracker = new MediaTracker (this);
tracker.addImage (img, 0);
tracker.waitForAll();
PixelGrabber grabber = new PixelGrabber(img, 0, 0, imageWidth, imageHeight, buffer, 0, imageWidth);
try {
grabber.grabPixels();
catch(InterruptedException e) {
e.printStackTrace();
if(rotateRight)
for(int x = 0; x < imageWidth; x++)
for(int y = 0; y < imageHeight; y++)
rotate[(x*imageHeight)+y] = buffer[((imageHeight-y-1)*imageWidth)+x];
else
for(int y = 0; y < imageHeight; y++)
for(int x = 0; x < imageWidth; x++)
buffer[(y*imageWidth)+x] = rotate[((imageWidth-x-1)*imageHeight)+y];
for(int y = 0; y < imageHeight; y++)
for(int x = 0; x < imageWidth; x++)
rotate[((imageWidth-x-1)*imageHeight)+y] = buffer[(y*imageWidth)+x];
rot = createImage(new MemoryImageSource(imageHeight, imageWidth, rotate, 0, imageHeight));
catch (Exception e)
e.printStackTrace();
return rot;
this is the code i use to scaled the image.
Image scaled = originalImage.getImage().getScaledInstance(
(int)(currentWidth * 1.5),
(int)(currentHeight * 1.5),
Image.SCALE_FAST);
I tried this method, it works and does what i want but the scrolling and loading is too slow.
public void paintComponent(Graphics g)
Graphics2D g2D = (Graphics2D)g;
g2D.rotate(Math.PI/2, (int)dimension.getWidth()/2, (int)dimension.getHeight()/2);
g2D.drawImage(image, 0,0,(int)dimension.getWidth(), (int)dimension.getHeight(), this);
Help plss.

Nvm got the answer :)

Flash crashing when using Command + Option + S for Scale and Rotate?

Flash crashing when using Command + Option + S for Scale and Rotate?
It's happening to me when I use those hotkeys
Please let me know if it's happening to you too.
I don't know the cause but I need a fix.
I'm using Adobe FLASH cs6 for Mac
My computer:
Mac mini
Mid 2011
Software OS X 10.8.1 (12B19)
-Line

With all due respect to your totally coindescending reply, this is a bug in Flash. Happens every 4-5 times I use that menu item. Been happening for months, but we just installed a Brand new iMac (1/13). Quadcore 3.4 16G RAM and 1TB Fusion drive. Fresh install of CS6. Not running any other 3rd Party Software. Problem STILL happens in new Flash docs with small, simple vector Graphics.
So instead of blaming the users computers, how about you guys just fix the effin' problem? Thanks.

IBooks Author books and iPhone 6 Plus

Will ibooks author books that have pictures, audio, video, and other widgets, be readable on iPhone 6 Plus?

It seems like apple would have announced this if it were possible. But we will find out shortly....

Ibooks author web links lost when preview to iPad

Created a long book with ibooks author including links to web sites. Works fine on Mac version but when I open the book on iPad ibooks, web links are lost and default to apple web site. What do I do to retain links for iPad version of ibooks?

No, catually I can't. I don't see my iPad nor my iPhone either in Image Capture, iPhoto, iTunes. They are nowhere. I even tried 3 different dock-USB cables. The cables are ok and I can charge the devices. But they won't be recognized by all the apps. This never happened before. The only thing that has changed recently is that I installed OSX Lion. Any connection ? What happened????

IBooks Author iOS6 and iPhone

Hi all, this probably can't be answered immediately as ios6 has only just been annaounced, but I'm wondering if iBooks made using iBooks Author might now be compatible with the iPhone/iPod Touch running ios6? rather than exclusively on for the iPad

There is no public discussion at this time that this will be the case.....that means no news to share, at least not right now.
Beta users are behind NDAs that otherwise do not permit chatting here, sorry.

Problems with Flash CC user interface. Mainly I can't seem to click certain buttons and input fields on various modal windows. (eg. Scale and Rotate, Sound Properties,

Hi there,
I'm wondering if anyone else is experiencing issues like this. I'm basically finding that a bunch of different buttons, fields, and tabs do not respond to my clicks. This seems to be spread out throughout the application.
I've had to work around most of this by using the tab and arrow keys to navigate around modal buttons and fields... but it is a bit of a pain.
There are some parts of the interface that can't be accessed via tabs and arrow keys... for example the ActionScript Tab on the Sound Properties window... there's no way to get to that... and clicking the tab itself does nothing, although I can see that the rollover state of the tab is activated.
I've ended up having to run Flash CS6 in order to set the export classes of sound files and that's a bigger pain.
Similar UI issues exist with other things... for example the color picker (eye dropper) seems to pick colors near, but not directly under itself.
I'll be honest... I'm running on Windows 7... via boot camp... on a Mac Book Pro with retina display... so the issues could stem from this combination. However... Flash CS6 does not have any of these issues... so I can only think that it is a Flash CC issue.
I appreciate any input you can provide. ( Although the obvious "run it on OSX instead" or "just use CS6" aren't the kinds of answers I'm looking for. I have my reasons for the setup. )
Thanks.
Cheerfully,
- JR

Thank you for the suggestion. I've just done the uninstall, clean, re-install process.
No luck.
Even the first-run modal that comes up to choose Sync Settings has the same problem. All three buttons will go to a rollover state if I mouse over them... however, none of them are clickable. The only clickable item is the OS window close button. If I use the TAB key to move from button to button it moves the yellow button selector accordingly. If I press the ENTER key it responds correctly. For some reason clicking is not working on these parts of the Flash CC UI.
*Note: This does not happen with all of the Flash CC UI elements... only some key ones (Save As - Confirm Overwrite, Symbol Properties and Swap Symbol dialog boxes also do not work with clicks, only with the keyboard navigation). Really a pain in the posterior.
Again, I'm wondering if this is an issue particular to my hardware/os combination but I have had no luck finding answers online.
Any other possible solutions out there?

I read about outside publisher assistance that helps get the books correctly formatted for uploading - any info on this? I found it yesterday while searching iBooks Author information and have lost it! :) thanks

Is this assistance, for a nominal fee, called aggregators? I can't find this info anymore, and wonder if anyone else has heard of this.
thanks,

I created a book in iBooks Author using the Photo Book template. When I rotate to portrait orientation, the photo or widget disappears and a table of contents appears with only the interactive media showing.

I created a book in iBooks Author using the Photo Book template. When I rotate to portrait orientation, the photo or widget disappears and a table of contents appears with only the interactive media showing.

Thanx for the prompt response, KT. I have indeed seen that thread, only just after I posted the question.
I have spent hours on the phone with what I now know is a call center in Texas on this question.
I think Apple could be a little more "hands on" with iBooks Author users, and it should also be pointed out that landscape photos will not display in portrait mode.
In my case, I used gallery widgets to display vertical photos, since they look better in portrait mode.
But instead of simply rotating, the page disappears and a TOC of interactive media appears. The gallery behaves as expected when tapped. This is not what I expected, but since the gallery works, I can live with it.
Right now I have "tickets" telling me to "fix" this "problem or to disable portrait mode.
I don't want to disable portrait mode.
Will Apple accept the books if I tell them this is not an "error?"

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.

Using Google GWT to create (Dashcode) widgets for iBook Author I would like to embed interactive widgets in iBooks using iBookAuthor. The widgets in question started life in Java but GWT has allowed them to be converted to javascript and to run on web pa

I would like to embed interactive widgets in iBooks using iBookAuthor. The widgets in question started life in Java but GWT has allowed them to be converted to javascript and to run on web pages (for example, http://softoption.us/content/node/437 scroll to the bottom). In theory, iBookAuthor can bring in most html5, and much javascript. The technique is to wrap the html in a folder, with 2 extra files, a plist and a default png and then change the extension of the folder to ‘.wdgt’. This is the technique for making Dashboard widgets for the Mac, and Apple even have the Dashcode software to do it. So what you really do is to make a Dashboard widget, then iBookAuthor can import it. So far, so good. And some folk have been doing this, for example http://www.prweb.com/releases/2012/2/prweb9242432.htm http://www.panophoto.org/forums/viewtopic.php?f=64&t=10417&p=158330#p158423 However, if you start with GWT and create a single page with one button and a Hello World, compile it, and get the WAR file (I use Eclipse here)… the Safari browser and others will run it properly (even on an iPad). Then if you wrap it, a proper Dashboard widget is created, which runs properly on a Mac. Then if you go to iBookAuthor and put a custom widget in the Text, then drag it in. It is accepted by the text and shown as being there. However, if you use Preview to look at it on an iPad, it is gone (or was never there in the first place). Anyone any ideas on this? [And iBook Author seems to give no warnings.] The widget is at https://dl.dropbox.com/u/46713473/Test6.wdgt.zip I have bells and whistles that I’d like to get into an iBook!
Thanks for any insights.
Martin

I do have a little to add, which might help someone. Indeed, opening a blank page and dragging the widget straight in seems good in difficult cases. But, actually, I was also able to insert successfully from the Toolbar especially to blank pages. So, it may have been something to do with the columns and stuff like that. Anyway back then the insertion would show in iBooks Author but not in the Preview on the iPad. I moved on to actual Google Web Toolkit output javascript. Basically I had three at hand to try: a Hello World with a button which went straight it, one of moderate complexity, (for example with a built in Lisp interpreter), which also went straight in, and finally a more complex one that initially was rejected by iBook Author. Author complained that there was an unsupported media file (of course, Author does not tell you which one it is, that would be too easy). [Remember, this was a proper working Dashboard widget which could be installed on a Mac]. Among other things I had read remarks about .gif files. When looking through the GWT war directory at the actual javascript etc files, I noticed there were two gifs there one called ‘clear.cache.gif ‘ and a second one called ‘0F89659FF3F324AE4116F700257E32BD.cache.gif’. (Now, there is obfuscation so the numbers here may be different from case to case.) The clear.cache.gif did not seem to be anything special. But the other one is an animation. It is three little boxes that twinkle (rather like a waiting spinning cursor). So, I opened that file and saved it to itself (that picks the top frame of the animation and saves only that, leaving you with an unanimated gif). The resulting widget drags and drops into iBooks Author (and seems to work properly at a quick glance). So, if you are having trouble with ‘unsupported media files’ converting animated gifs into unanimated gifs might help in some cases.

Ibook Author can't preview message

Hi,
I have almost finished my book in iBook Author. Today I added short titles to the videos. I've got 50 videos throughout the book. But when I started to Preview the book on iPad IBook Author says it Can't preview. it loaded perfectly fine on iPad till today. This is a screenshot.
After I added the video titles my file jumped up from 170Mb to 225Mb. I know the file is huge but how 50 short lines can expand it to 55 MB.
May the file size be the reason that it doesn't upload the book to iPad? I uploaded for the test the previous versions and it works fine, but not the new file.
Does IBA have a file size limitation to upload it to iPad?
Any ideas?
Best regards,
JaSok

Issue resolved.
I think it's a file size issue. I managed to reduce the file back to 170 MB and it loads fine now. But the reason of file expansion to 50 MB was that I applied the character style for video labels to make it ALL CAPS via Widget tool. This simple step added 50MB to the file.

Ibooks 2 and iBooks Author!

Hi guys!!
I have some questions about the iBooks 2 Store and the iBooks Author, please help me further with them.
1. Can anyone post self-made books for sale or for free download in iBooks 2 Store? (For example, students at a school that has made books on a topic, they learned about?)
2. Is Apple strict with photos and other material taken from the internet, google or books etc? (Must every materials be selv produced?)
3. How long does it take to get a book published in iBooks 2, so other students and teachers can download the same book?
4. Does someone have a guide on how to publish the book in iBooks 2 Store?
Thank you in advance!

1.) See iBooks Author: Publishing and distribution FAQ - Support- but, yes, anyone...once they have completed the required agreements and been accepted into the program. There are separate programs for 'paid' and 'free'. You might want to utilize the method of putting free books on your own server and not going thru the store.at all, if the audience is limited to other students in your school, as an example.
2.) Of course You are expected to be able to show proof-of-right-to-use should Apple ask.
3.) If you go through the store it can from a few to several days. 'Text' books for edu can take longer.
4.) When you sign up, you are able to download guides for iTunes Producer, which is the tool used to submit books.
Good luck
Ken

I am a teacher and want to distribute a textbook I created using iBooks Author through Ibooks. We are not 1 to 1 and students share devices on a cart. Can I publish and distribute the book if it is used by multiple students?

Title says it. I created a textbook using Ibooks Author and want to load it on my class set of 30 iPads that are used by 5 different groups of students throughout the day. It is not a 1 to 1 device. Is there a problem with doing this as the Apple ID would be a generic that downloads the content many times on each iPad for my students?

The two processes are so unalike that you need to bone up on what they involve before answering, I think...you can't just shrug and expect specific help, sorry.
See iBooks Author: Publishing and distribution FAQ - Support
Distribution isn't automatically like iOS apps, where the store is involved by default.
You are free to put your .ibook file on a school server/your own server, and anyone can download for free and use it, independent of any Apple ID and the app store. If you want to restrict to your school/students, put it behind a login.
You can put it in the store as a free download and any Apple ID can download and use via any iTunes Account. If you sell via the store, each download/purchase is tied to the Apple ID used to facilitate that transaction. This is not a requirement.
Again, you need to become more familiar with the distribution process and not worry so much about the Apple ID scheme involved at the moment so you can make an informed decision, I think
