Has the Book Proofer app been updated? Apple recommends using the ibooks app on your mac and iOS device to preview your books. If your EPUB includes interactive content, the book proofer in Apple Books lets you see and interact with your book the way your readers will; you can make sure . Sorry, I didn't realize that. I've only done "paid for" books so far.

Email. Prior to OS X Yosemite, Apple had a standalone app called Book Proofer that EPUB producers could use to test EPUB files on iOS. Book Proofer User Guide Apple - Download as PDF File .pdf), Text File .txt) or read online. Apple Book Proofer. I am trying to drag my book in ePub format created with Book Creator into Book Proofer. I keep getting the error message "book.

Of course they could. Should they have done so? Of course. Then again, given the trouble they've been having getting the bugs out of Yosemite, perhaps the holes in their iBook workflow escaped their attention.

There are a few words for that kind of work: And it's great, if belatedly so, that they finally provide a reader app for iBooks so that now we can bypass iTunes for proofing and reading purposes alike. And yet Apple still left an unnecessary hole in the workflow. The rest of us are fortunate you - and Mr. Durrant - have gone to all the trouble of figuring this out for us. Don't get me wrong - I'm grateful for your efforts.

And Apple has, however inadvertently, provided you with work explaining how to use their not-ready-for-primetime software. I can't help thinking, though, that you would have nearly as much work explaining their software even if it were complete. That said, I see no reason to apologize for, to try to brush off or ignore Apple's oversights in this matter. If they're not held accountable for these problems, they'll have little incentive to do a better job going forward - as they so clearly lacked the incentive to do the job right the first time, or even the second and third time.

Not to aggrandize myself, but someone's got to point out that the emperor is walking around in public in his skivvies. Apple's Book Proofer was meant as a convenience utility for those book publishers who had signed up to sell their books through the iBooks Store.

It was not meant for the general public. The new proofing capability built into iBooks is still not meant for the general public, but Apple is making it available without requiring you sign up with Apple Connect as a book publisher.

You are faulting Apple for failing at a task that it has never, in fact, promised to undertake: Nonetheless, Apple has provided EPUB export capabilities in Pages as a convenience for Pages users, and it has provided EPUB proofing capabilities for book publishers whether professional or amateur as a convenience for them.

Where did I ever say, or even imply, that Apple "owned" or "curated" the ePub format? That's a straw man from way out in left field. Apple wants people to write books for the iBook Store and to sell them there. The harder they make that for writers of any kind - and publishers - the fewer books they will attract. It's just that simple. And they have made some tools available for that purpose, but left an important one out. It's hard to see why they've chosen to make it difficult at any point.

But they have. You choose not to see this as a problem because you've already learned the steps to their song and dance. But in these days of a booming self-publishing industry - where the distinction between professional and amateur author is all but irrelevant yet another straw man - not everyone has acquired your level of expertise.

Once upon a time Apple was known for ease of use. With writing books for the iBook Store, ease of use was not even on their radar. Yes, there are other ePub authoring tools, most of them even harder to use than Apple's hence the poor quality of so many ebooks. As for other ebook readers, they can't handle iBooks.

So that's another straw man argument - as is the jape about whether they "promised" to create such tools or not. Promise has nothing to do with it.

I am faulting Apple for failing at a task that is clearly relevant to their business: They sell ebooks. And they are in competition with site, the pound gorilla of the publishing business. Where does making it harder to create content for the iBook Store facilitate that competition for them?

Bluntly put, it does not. Apple did not provide the ePub export feature for Pages out of the goodness of their heart. Nor did they offer up the iBooks app because of their generous nature. These were calculated business decisions, nothing more.

Take into account that users will have control over font face, font size, and justification in Flowing books — test your book to make sure it works in most, if not all, cases. Font sizes should be defined in em or px , not by name for example, x-small, small, medium, large.

How to Create a Custom Sample of a Fixed Layout Read Aloud Book for the iBooks Store

The main text of a book should either not have a defined font-size or should have a font-size of 1em. This will ensure ideal readability and font scaling. Check the font hinting and metrics on embedded fonts to avoid layout problems. Be sure to test them to avoid layout issues and cropped text. For more information about font mangling, see http: This section describes asset requirements for video and audio and how to embed the content for EPUB books only.

For audio and video requirements for books created with iBooks Author, see the knowledge base articles on the Apple Support Site:. When sending books with embedded audio or video content, keep in mind that the maximum file size for the. For usability's sake, the maximum recommended size is MB. Larger files take longer to download and may become unwieldy on older devices. Apple recommends that audio be encoded using iTunes as follows with.

See Embedding Audio and Video for an example of embedding audio. All videos must begin and end with at least one black frame. All encoded content must include pixel aspect ratio pasp that defines content as either 4: Select the H.

When using the anamorphic encoder instructions, select the gear across from the Aspect Ratio scroll and select This creates a Pixel Aspect value that appears in the Geometry pane. Click the Preview button on the Compressor Batch window to verify the accuracy of the crop values and also to access the source and setting buttons to test the results of the aspect ratio setting. Video files must be H. The posterframe is the image that displays inline in the book. It is usually a clip or frame from the video.

The posterframe should be the same size and aspect ratio as the video. The maximum file size for the. The larger the file is, the longer it will take for a consumer to download your book. It may take longer for your book to appear on Apple Books because the files need to be checked by Apple for quality control purposes. Note that audio and video files do not have DRM applied in the final book, regardless of contract or the metadata; however, DRM is applied to the text in the book.

Fallback video content is not currently supported. All video must be h. For optimal user experience, audio and video content should appear on its own line in the EPUB and be centered on the page using text-align: Apple Books provides default dimensions for audio and video.

The standard video pane dimensions are a 1: However, the width can also be defined using CSS, ideally as a percentage of the screen width.

Apple Books will ensure that video and audio fit on a page, no matter the screen size. To avoid layout issues, do not set an explicit height on video elements. To enable readers to revisit embedded media, Apple recommends that you provide entries in the Table of Content that point to media.

Note that the video tag must include the required poster image. The customer sees the poster image in the text and clicks the image to start the video. The controls attribute allows readers to play, pause, and scrub the media; autoplay will automatically start playing the audio or video without stopping. The controls and autoplay attributes are boolean; including them will activate the attribute no matter their value.

Note that although autoplay is supported, Apple recommends that it not be used. It is best to allow readers to control their own reading experience as they know the environment in which they are reading. The following two examples show how to embed audio and video content in the EPUB, followed by a screenshot of how the audio and video would appear on the device:.

Links can be within a document, as in the case of an index or endnotes, or can link to the web or other external resources such as an author or publisher website. Apple Books also has a very simple linking architecture that enables you to link directly to books within Apple Books. This could be used for marketing from your own website or online advertisements, or it could be used within an EPUB to direct a customer to other related titles at the end of a book.

You can also create your own link based on the book's ISBN. Apple Books will automatically include a page at the end of Flowing books that includes links to other books by the same author, prioritized by most popular. You can link to a specific location, such as a figure, chapter, section, or page number.

If the other book was created using iBooks Author, you can link to a specific location in it using the same link structure as above, but include the asset ID in the link. In the example below, the asset ID is To link to an EPUB. Control-click or right-click on Windows the book on Apple Books and copy the link.

Note that linking to a specific part of a different book is only supported for books created with iBooks Author. The links will open in Apple Books. To customize the style and color of links, you can use CSS. If you define the color of the link, you must also include the specified-fonts layout metadata.

See Defining Book Layout Metadata. When the image is tapped, it opens the PDF in a new window where the reader can pan and zoom-in. Larger PDFs may also cause poor performance on some devices. This section provides information and tips for creating interactivity using JavaScript. Apple Books supports JavaScript similarly to Safari. In books, JavaScript allows for features like drag and drop, and touch or mouse events to initiate audio or animation.

However, scripts developed for books should take into account the following best practices:. Develop scripts that perform well on both macOS and iOS devices. Interactivity on desktop computers requires input from a mouse while interactivity on iOS devices require touch input.

When developing interactive books, be mindful of file size and the amount of interactivity on each page. Interactivity can be a great addition to a book, but good performance must be a priority.

Books must not rely on external resources. Do not use JavaScript to access resources outside of the book. Books must be self-contained. Books must not include databases. Do not include these resources for interactivity in your books. Avoid using the JavaScript alert feature.

Apple recommends that you not use the JavaScript alert feature, which is frequently used to alert users of errors.

If you choose to use this feature, keep in mind while you are crafting these alerts that they will be seen by your readers. The following sections discuss the technical considerations and design tips to keep in mind when designing content for books with JavaScript interactivity.

By default, Apple Books recognizes gestures and clicks to cue menus, pagination, and zoom. However, in books with JavaScript interactivity, Apple Books needs to know when to ignore gestures and clicks so that the reader can interact with the interactive portions of your book without prompting Apple Books' user interface options to appear.

You can disable this default behavior for the interactive element by sending the preventDefault message to the event object. It is important to keep a significant portion of the page edge unaffected by preventDefault to allow the reader to turn the page.

Design interactive books to work on both iOS devices and macOS. Interactivity on desktop computers use input from a mouse while interactivity on iOS devices use touch input. This means that your script must determine if it should provide a touch or mouse event as required by that platform. You can query if a platform supports mouse or touch by using hasFeature as defined in the EPUB 3 spec http: For example, if navigator.

If your book uses features that are specific to iOS like the accelerometer or multi-finger gestures, you need to include input alternatives, like buttons, that are supported on desktop computers.

Keep in mind that a finger is larger than a mouse, so interactive objects should have a hit area that's large enough for a finger. Because Apple Books will scale the page to fit the screen of the device, the size of the hit area is relative to the page size defined in the viewport and may vary for different devices.

When placing interactive objects, avoid placing them close to page edges and text. Objects too close to the edge of the page may cause the reader to unintentionally turn the page. Similarly, objects placed too close to text may cause the reader to unintentionally trigger the re-reading of a word in read aloud content. Most of the interaction in a book should have a cue so that the reader knows what they can interact with.

On macOS, you can use CSS to style the mouse so that interactive areas are indicated with a pointer see http: Animate or move elements on a page, alerting the reader that elements on the page or in the book can have interaction.

In the example below, the title page begins as a blank page, but has text and images that move onto the screen. This example indicates interactivity in the following pages of the book. Use bold formatting or add a glow behind words that trigger sound or animation.

In the example below, touching winds triggers a wind noise. Add a glow, pulse, or wiggle to an interactive object. In the example below, the flower on the left is glowing, the flower in the middle is pulsing, and the flower on the right is wiggling. Have an animatable element perform a behavior that prompts the reader to interact with the other elements.

In the example below, the pulsing stars and blinking eyes invite the reader to discover that the stars can be interacted with, and that the moon can be dragged across the screen.

Create a scene with an out of place element, an unusual blank area, or incomplete image that prompts the reader to investigate the odd element, fill in the blank, or complete the image. In the two examples below, the single red flower invites the reader to interact with the other flower stalks or the empty hillside to complete the flowered landscape. Design elements to feel separate from rest of page, as if they were on a separate layer.

When working with drag and drop elements, be sure to keep them behind any text in your book, like in the example below. Make the element float, wiggle, or move. In the example below, the rotating halo around the sun invites readers to drag the sun across the screen.

This example contains examples of key interactions: Each page of an interactive, Fixed Layout book is a separate web view, similar to two Safari windows next to each other. Content is isolated on each page with the spine as a firm barrier between the two pages.

The body must have dimensions defined in the CSS identical to the aspect ratio of the viewport dimensions. Image optimization is key for improving performance. This creates smoother transitions because they are hardware accelerated, but should be reserved for high-priority elements. Performance is best when JavaScript is tailored to the book.

Third-party JavaScript libraries can often be large and may result in poor performance. All books with JavaScript interactivity designed for Apple Books should follow these technical guidelines and requirements:.

When a page has loaded, ibooks. The addition of this class can be used to trigger animations. Sometimes, a developer wants to fire a delayed event after the content has loaded. By adding ibooks-deferred-event to an element, ibooks. This delay can be defined on a per element basis by adding a HTML attribute data-deferred-event-delay and setting the desired value in milliseconds. Draggable elements respond to touch events and can be moved around the page.

Any element with a CSS class ibooks-stampable will act as a parent container for stamp-able elements. Stamp-able elements respond to touch gestures; on touch, ibooks. You can then style the appended element. It is worth noting that SVG patches are especially useful when defining irregular shaped hit areas, such as hills. Additionally, the audio source playhead can be reset each time the element is touched by defining data-ibooks-audio-reset-on-play.

Read aloud can be paused after the media has played or is paused by setting an HTML attribute: See Embedding Read Aloud Controls for more information. If desired, many of the ibooks. If your EPUB includes interactive content, the book proofer in Apple Books lets you see and interact with your book the way your readers will; you can make sure everything looks and works to your satisfaction before you distribute your book or submit it for sale on Apple Books. If so, you're ready to create your EPUB proof.

If not, follow these steps:. Launch Terminal. During book development, using this tool allows you to more easily modify, debug, and optimize your book. All books must adhere to EPUB standards. To ensure quality content, your book must pass validation at the time of import.

There are a few issues commonly encountered with books that prevent them from importing into the Apple Books system. Review all books carefully to ensure that the following are addressed prior to delivery:.

Books containing unmanifested files will fail import, as these files are by definition not intentionally included. Any books that are improperly encoded will fail import, so it is important to use the correct character encodings.

If you use custom attributes, they must be HTML5 data attributes. A data attribute is an attribute that exists outside of a namespace and starts with the string data-. Each namespace is declared using a URL and the attribute xmlns or xmlns: For example, xmlns: In the above declaration, xmlns: After you declare it, you can use the prefix in front of any element or attribute name separated by a colon.

This identifies which XML vocabulary that element or attribute is referencing. To resolve the issue, change the element or attribute to one that is valid.

Apple Books Asset Guide 5.2.9

Apple Books automatically creates samples for all books except read aloud books. What the sample is made up of depends on the type of book. If you do not want Apple Books to cut the sample automatically, you can create a separate, custom. Note that not all tools support this option.

If you contract with a third party to manage your content delivery, they should be able to do this for you. Contact your delivery company directly for more details. A downloadd book replaces its sample in the customer's library. Be sure to include all sample content in the full book. If a book is predominantly text, the sample is based on a percentage of the number of words the percentage used is specified in your contract.

Where the sample begins can vary depending on how the book has been structured. The words on which the percentage is calculated are counted from the beginning of the book. For flowing books, the beginning is determined by finding the first landmark where the epub: If that attribute is specified, Apple Books starts cutting the sample from the publication component in the spine item referenced by the href attribute in the landmark. Any images, movies, or audio included in that percentage will be included in the sample.

If the "bodymatter" attribute is not specified in the Landmarks structure, Apple Books looks for the first landmark where the epub: It is recommended that the publication component referenced by the href attribute in the "bodymatter" landmark not be listed close to the last item on the list of spine items.

When cutting the sample based on percentage of words, Apple Books could potentially include publication components that precede the referenced spine item, which could result in Apple Books including the entire book in the sample. See Defining Book Layout Metadata for instructions. The pre-paginated option determines how the sample is cut.

Without this option, the sample is cut as if the content is a text-heavy book like a novel. With this option, the sample is cut based on a percentage of the number of pages rather than word count.

Apple Books determines the first page of the book each page of a Fixed Layout Book, whether a single page or a two-page spread, must be a separate XHTML file and then cuts the sample from a percentage of total page count.

For optimal samples, include epub: Note that a Landmarks nav is required for Fixed Layout books only if you do not provide a custom sample. To provide an optimal quality sample for books with interactive content, Apple recommends that you supply your own custom sample due to the dynamic, complex nature of an interactive book. However, a custom sample is optional for books with interactive content. To create a custom sample, create a separate. Automatically-generated samples are not supported for books with JavaScript interactivity if they are also read aloud.

Read aloud content requires a custom sample. Books created with iBooks Author require a sample file to be offered on Apple Books and iBooks Author creates one for you when you publish your book. During the publishing process iBooks Author creates a package with the extension. Then at the end of that export process, iTunes Producer opens the package for you to add your metadata and submit your book to Apple Books. This chapter describes guidelines for creating Flowing Books. Refer to Digital Book Essentials for best practices that apply to all types of books.

In Flowing books, supplying Landmarks in the Navigation document is recommended but not required. Apple Books creates a page break between documents. If specifying line-height, extra spacing between text blocks and any padding around images should be a multiple of the specified line-height to keep text aligned across the spine.

Nonlinear content includes documents that supplement the main content, but are outside the reading flow of the book.

Book Proofer

That link is a standard anchor element and can be associated with both text or an image. Nonlinear documents are not supported for Fixed Layout books. To indicate if a spine item is nonlinear, specify a value of no for the optional linear attribute. Note that the linear attribute is not required on spine items.

When a reader selects a link that leads to a nonlinear document, the content opens in a separate window that overlays the book.

Because the window is outside the flow of the book, it maintains its layout and formatting. The content is searchable from within the book and can be panned and zoomed in on.

The following graphic shows an example of a nonlinear document. If the linear attribute is set to yes , delivery will fail. Apple Books has several viewing themes that the reader can select for Flowing books. These include Book, Full Screen, and Scroll. The Scroll theme scrolls vertically for books with horizontal text, and scrolls horizontally for books with vertical text. By default, Japanese and Chinese books scroll horizontally, while all other languages scroll vertically.

To redefine the scroll direction, the book must include the following metadata in the. Possible values are vertical , horizontal , and default. This example is appropriate for a book with horizontal Japanese or Chinese text. When rendered with Apple Books' Scroll theme, horizontal text is most easily read scrolling top to bottom on the vertical axis.

Apple Books automatically recognizes tables. In Flowing books, Apple Books sizes large tables to fit within the width of the page. When a reader double taps the table, the table opens in a new web view that overlays the book. In this web view, the reader can pan and zoom in on the table. When specifying line-height , set the value to a unit-less multiple of the font-size , for example, line-height: This chapter describes guidelines for creating Fixed Layout books.

Fixed Layout books lend themselves to interactive content, so be sure to check out Books with Javascript Interactivity in Chapter 2. Note that nonlinear documents are not supported for Fixed Layout books.

Fixed Layout books are used to create highly-designed books like children's picture books, cookbooks, and art books. Fixed Layout books support text overlapping images and full-bleed images—two features not possible with Flowing books. These features are made possible with the support of CSS positioning. This chapter provides guidelines to follow when creating a Fixed Layout book.

Not following these guidelines could adversely affect the way the book is displayed. Fixed Layout is a global definition that affects an entire book. Fixed Layout cannot be used on a per-page basis.

Using EPUB 3, you have the choice of creating a single spread using one or two content documents. By default, a book with two documents per spread maintains the book-like appearance including the book spine, pages, and page curl.

By default, a book with a single document per spread does not include the book-like appearance and instead the spread looks like a single sheet, similar to the PDF view. In Fixed Layout books that have two documents per spread, the first page of a left-to-right paginated book for example, English will be on the right side of the spread. In a right-to-left paginated book for example, Japanese , the first page of content will be on the left page of the spread.

Generally, this first page is the cover page. Apple Books uses these dimensions to determine the aspect ratio of the book. See Defining Book Layout Metadata for more information. The Landmarks navigation structure is required for Fixed Layout books only if you do not provide a custom sample.

Apple Books references the Landmarks when cutting the sample. It allows Apple Books to determine where the main content of the book starts see Landmarks. Defines whether a book is a flowing book or a Fixed Layout book. Supported values are reflowable standard Flowing book and pre-paginated Fixed Layout book. This is equivalent to fixed-layout: Defines if there are one or two content documents per spread. Supported values are auto , both , and none. Must be defined if your book contains embedded fonts.

This is equivalent to specified-fonts: You do not need to use embedded fonts in this instance. Apple Books provides a preference that a user can choose to display the text in a book to full justification. This option overrides any text alignment you specify and justifies all paragraphs in a book, including all headings.

You can preserve your text alignment by using the specified-fonts attribute and setting it to true. This attribute preserves the font settings as specified in your CSS stylesheet, as long as the user does not choose a different font when reading the book. When this happens, the justification for paragraphs returns to the user preference, but the text alignment for your headings is preserved.

Fixed Layout books include a thumbnail table of contents allowing for easy visual navigation. This visual table of contents is the default for Fixed Layout books. The list table of contents is very helpful with large books with distinct chapters or sections such as cookbooks.

However, the list table of contents is not very helpful with a short picture book and may be suppressed for those books.

The following shows a thumbnail table of contents:. In Fixed Layout books, epub: For example, the first page of the book is page 1 by default, but in some books, this may be the cover page and shouldn't be numbered. You can use pageList or epub: Similarly, you can define i, ii, iii or a, b, c then 1, 2, 3 for page numbers.

The following shows an EPUB 3 example of epub: In addition to the font recommendations in Fonts , the following apply to working with fonts in Fixed Layout books:.

Do not use fractional measurements for letter spacing, font size, and text placement. An example of a fractional measurement is 5. In addition to the image recommendations in Interior Image Requirements , the following apply to working with images in Fixed Layout books:.

To reduce file size, use JPEG for any images that do not require transparency. Using JPEGs results in a smaller file size and better performance. We recommend using a quality of 85 for JPEGs. Images inside Fixed Layout books must not exceed 4 million pixels. You can calculate whether an image inside the book file exceeds 4 million pixels by multiplying the height and width of the image. Because Apple Books scales the book to fit within the viewport, both landscape-dominant and portrait-dominant books will maintain their intended layout in either orientation of the device, even after an orientation change.
