Cropping Your eBook – PDFill PDF Tools

hindlerI find myself being obsessed with eBooks lately — probably because I’ve just entered the world. But while making my first steps, I keep discovering new and impressive feats.

What’s The Fuss About?
Reading on an eReader is fantastic. You won’t hear me saying anything negative in that area. But to be able to enjoy a good read, you first need to be able to read the damn thing.
Normally, most eReaders come equipped with a zooming feature. A hit of a button can take your text up to ridiculous point sizes. The only problem is when you’ve got eBooks that are in fact only scans of paper novels and not quite eReader eBook format. Being bitmap images, your eReader cannot rescale the individual text areas, and you end up with A4 or A5 pages on a 5″ display.
convert scanned pages to ereader
A related problem occurs when you’ve got pre-formatted text. Resizing of course works great, but your once perfect text alignments are now screwed up. A great example are coding eBooks, where the alignment and formatting of text go a great way to making it accessible in eReader eBook format.

Cropping Your eBook – PDFill PDF Tools

Yes, the solution is as simple as that. We’re going to crop away those unnecessary margins. If you look at you’re document, you’ll probably notice that it has a ridiculous amount of whitespace at either side. Sure, it looks fine and makes the document printer-friendly, but if your document gets ‘scaled to fit’, that’s one thing you don’t need.
If you’re on a Mac, you can just use Preview for the job. Same story if you happen to have Adobe Acrobat Pro. There’s not a lot of freeware that allows you to work those PDFs, but PDFill PDF Tools works just fine.
Know that although the real PDFill suite is proprietary, PDF Tools is complete free, for personal AND commercial use. No need to worry about a watermark either.
ereader ebook format
In the application, be sure to highlight All pages. Discovering the correct margin settings is trial and error – 1″ left and right, and 1.2″ top and bottom works if you don’t mind losing the page number.
Strange enough, this often suffices to make the document readable. You also might want to adjust your eReader to a landscape view.

Taking Apart The Bitmaps

Sometimes the resulting document still doesn’t meet your requirements. Your other option is a little more drastic, but it continues where the previous method left of. Basically, what we’re going to do is cut all our pages in two pieces – top and bottom – with overlapping parts. First, we’re doing a double crop, and then we’ll need to put all pages back together in the right other.
Start out by duplicating your document and putting it in separate foldersCrop one of the documents towards the top half, the other to the bottom.
Next, still using the same application, export the first (top) document to a series of PNG images, and the second (bottom) document to TIFF.
view scans on ereader
You’ll notice that you’ve got two identically named series of images, with the only difference being the extension. You can now safely join those two collections in one folder. If you sort the files by name, you’ll notice that the pages have mixed perfectly (that’s because PNG comes before TIFF in the alphabet).
How To Convert Scanned Pages Into eReader eBook Format pdftool images pdf
Still using the same application, we can now join those images into one PDF. The PNG/TIFF export alphabet trick has saved you a ton of time moving the page halves into place.
Note that you can also use it if you’ve got a double scan (two pages, side by side). First making a vertical, then a horizontal crop separation.
Know any other cool tricks? Let us know in the comments section below!

What is the best way to scan paper books to digital ebooks?

What you want to accomplish is not a quick and easy task. You need to capture images of the book pages, clean the images, and depending on your desire, convert them to text, format them, and generate files in your desired format. I agree with idiotprogrammer and the others in the comments: if you can already buy an ebook version or find a (legal) free copy online, you are much better off doing that.
That said, if you still want to scan in your books, here is are the basics to get you started:

1. Decide what you want

Creating your own ebooks with searchable, reflowable text (changes to fit screen) and table of contents is a complicated process and it really helps if you are good with computers.
Creating PDF files out of scanned book images is pretty easy, and it will accomplish your basic goal. However, you won't be able to search the text or highlight things, and the text won't reflow to fit your device's screen. I would highly recommend you choose this route if you're only concerned about being able to read your books.

2. Scan the book

The quickest way to capture "scans" of book pages is with a camera, but you will need some sort of rig that holds the book and camera in a fixed position. You might start by looking at some of the ideas at diybookscanner.org. The forum there has a lot of great info. (I personally own an Archivist Quill, but I'm not telling you to spend that kind of money)
If you have a smartphone and a little bit of handiness, you might try making something like this iPhone book scanner as a start.
If you have a flatbed scanner, you could also use that, it's just rather slow, especially if you're capturing full color scans (voice of experience).
Scanners capture pretty accurate images, but images captured with a camera will be slightly keystoned, so if that bothers you, you might want to try to find a dekeystoning script. I use one I found on the diybookscanner forums.

3. Clean the images

Use a program like ScanTailor to clean up the images.
If you want to remove the page color and darken up the text, I recommend using the GIMP on your ScanTailor output files. Either the "Colors > Levels" or "Colors > Curves" tool would work well for this. Altering the images one at a time would be a huge task, so figure out the adjustments you want to make and then use the BIMP for GIMP plugin to batch apply them.

4a. Generate a PDF

If you choose the easy route, this is the last step. Use a program of your choice to convert your image files to a pdf. I do this with imagemagick, but imagemagick is a command line tool, so depending on your computer know-how you might want to look for a better option for you.

4b. OCR the images

If you want to create "proper" ebooks out of your scanned images, you will need to run the cleaned images through an OCR program. tesseract is a really good free tool to do this, but once again it is a command line tool.

5. Proofread and correct the text outputs

This step is really time-consuming. In this step you will read the entire book very carefully looking for "scannos" (typographical errors made by the OCR software as it converted the images to text). If you don't do this, your ebook will be full of errors.

6. Create the ePub file

This step can be rather complicated. Use a tool like Sigil or Calibre to make your text files into an ePub. Sigil is a great tool, and I've used it quite a lot. Unless you are an experienced HTML programmer, it would probably be best if you try to avoid anything other than the basic formatting options the program makes available to you.

7. Convert your ePub to KF8

You can use Calibre for this, but I'd recommend using kindlegen, Amazon's official conversion tool. Once again, a command line tool.

Конвертирование файлов для eink электронных книг


У меня есть электронная читалка azbooka n516, которая является русифицированным вариантом китайской читалки Hanvon n516. 
Есть проблема - pdf-файлы, в большинстве случаев (кроме оптимизированных для небольших экранов) рассчитаны на печать в формате A4. На пятидюймовой читалке текст в них слишком мелкий в режиме без горизонтального скроллинга. Я поделюсь с вами несколькими программами для подготовки файлов к просмотру на таком устройстве.

k2pdfopt - автоматическая оптимизация PDF

Начну с самого вкусного: k2pdfopt (Win/Linux)
Эта программа - настоящее открытие. Если кратко - перетащи pdf-файл на иконку программы и получи оптимизированный. 
Подробнее: многие файлы в pdf содержат поля по краям без текста, а также верстаются в две колонки (журнал OpenSource, который я выбрал для теста, как раз оказался двухколоночным). Программа обрабатывает все поданные на вход файлы, а также может создать pdf-файл из изображений. Работает полностью автоматически в консольном режиме, но, при необходимости, настраивается. У автора программы kindle и его программа оптимизирована под 6 дюймов. Но и на моих пяти журнал прекрасно читался без масштабирования и горизонтальной прокрутки. Шикарная программа!
screenshot

Briss - ручная обработка PDF

Следующая программа - briss (Java)
Отличная программа для ручного удаления полей. Пригодится для тех документов, с которыми не справился k2pdfopt. Ничего замысловатого - выделяете важную область на экране, затем обрезаете все остальное. В процессе тестирования я обнаружил, что разбивать колонки на страницы она тоже умеет, пример на скриншоте:

Cut2Col - ручная разбивка двухколоночных документов.

Следующий кандидат - cut2col (Java) 
Тут всё очень просто - это программа для ручной обработки двухколоночных файлов.

Другие программы

Вот ещё несколько не менее достойных программ, на обзор которых меня не хватило:
  • Calibre - каталогизатор, конвертер, может конвертировать rss-ленты. Тормозной и неудобный, но многофункциональный, свободный, кроссплатформенный и имеет множество плагинов. Есть плагин для интеграции с goodreads.
  • PDF Masher - конвертирование PDF в MOBI/EPUB, более умное и настраиваемое, чем в Calibre (сравнение от автора программы)
  • jPdfTweak - шцейцарский (армейский?) нож для работы с PDF.
  • Papercrop - аналог k2pdfopt
  • Hamstersoft Ebook Converter - конвертер для windows, красивый и удобный, основан на коде calibre.

Как я использую Evernote

Решил кратенько описать как я использую Evernote.
Раньше у меня было несколько тематических блокнотов, например отдельный блокнот для полезных материалов по одному аспекту моей работы, ещё один — для другого аспекта, третий – для заметок про воспитание ребенка. Потом я понял, что в таком виде у меня блокноты перекликаются с тегами и не несут никакой пользы. Я подумал, что отдельные блокноты имеют смысл только для некоторых «особенных» заметок, например блокнот «Черновики», в котором начинают свою жизнь черновики для статей. Черновики я не ищу поиском, я открываю блокнот и смотрю что у меня есть дописать и опубликовать. А для основной массы информации у меня есть четыре блокнота: архив, чаты, quick question и мусор.
В первый я сохраняю различные статьи и полезные материалы.
Во второй сохраняю важные рабочие переписки из skype на всякий случай, потому что искать что-то потом в скайпе очень тяжело и неудобно.
Quick question — идея, которую я почерпнул у Brett Terpstra, только у него для этого используется небольшой скрипт. Идея состоит в том, чтобы записывать пары вопрос-ответ в таком виде, который будет удобен для поиска. Например, в заголовок заметки я пишу «куда я спрятал запасные ключи», или «какой компонент я использовал в проекте X для того-то и того-то». А в теле заметки ответ. Меня несколько раз это выручало в поиске информации, которую я раньше не считал достойной для записывания куда-нибудь.
А мусор это у меня своеобразный аналог архива, только не для статей и материалов, а для каких-то вырезок или коротких мыслей. Для остальной информации есть специальные блокноты.
Кроме всего этого, я делаю заметки на диктофон, когда неудобно набирать текст. Иногда прикрепляю в Evernote файлы, скриншоты. Мне очень нравится, что заметки в Evernote индексируются в spotlight (очень жду этого и в DayOne). А ещё, есть очень удобный Alfred Workflow для работы с Evernote.
Пока это черновик моей организации информации, может быть придумаю что-то более удобное.

You can view the list of supported keyboard shortcuts from Menu > Help > Keyboard Shortcuts or simply use Ctrl+K in Windows and Command+K in Mac to get the list of keyboard shortcuts. For example, enter Ctrl+O to open a book; enter Ctrl+E to go to end of the book; enter Ctrl+T to open Table of Contents.
Q18. How can I see the conversion log for my current book?
A18. To view the conversion log for a book that is currently open, click menu on the top left and select View > Conversion Log. If your book fails conversion, you will be able to open the conversion log through error dialog.
Q19. Kindle Previewer lets me preview and validate my eBooks before I publish them to Kindle. Does Amazon provide any tools for creating eBooks?
A19. Yes, Amazon provides Kindle Create, Kindle Create Add-in for Microsoft Word, Kindle Textbook Creator, Kindle Comic Creator, and Kindle Kids’ Book Creator for creating eBooks in Kindle format. Each of these Kindle authoring applications lets you add unique reading features that are optimized for each book category. We recommend choosing the tool that lets you add the reading features that most closely match the reading experience you want to create for your readers.

Troubleshooting - Frequently asked questions:
Q1. Why can I not preview my mobi book in the Kindle E-reader device mode?
A1. The Kindle E-reader device mode does not support preview of books in the older generation Mobi 7 format. We recommend converting your Mobi 7 book to EPUB so that you can preview your books using all the device modes and see if Enhanced Typesetting is supported for your book.
Q2. I see small boxes instead of the actual text in the table of contents while previewing an Indic language eBook on my Windows PC. What should I do?
A2. This can happen when your machine does not have the necessary fonts to display the text. You can resolve this by installing the corresponding language pack from Language Control Panel on your Windows PC. You might have to restart your machine for the installation to take effect on your computer.
Q3. I am unable to preview my eBook in Word format. What could be the reason?
A3. Some of the potential reasons could be: 
• The file is password protected. 
• The file name contains non-ASCII characters. 
• The eBook was created using an old version of Word (Example: Microsoft Word 97 or before). 
• The eBook is in a language other than English. 
Q4. Why do I not get an option to navigate by tables or lists for some books?
A4. The ‘Navigate by’ feature is only available for books that support Enhanced Typesetting. If your book supports Enhanced Typesetting, the ‘Enhanced Typesetting’ label is displayed under the ‘Device’ menu in the Inspector window. Also, the options that you see under ‘Navigate by’ are populated depending on the content in your book. If there are no tables in your book, you will not see an option to navigate by tables.
Q5. For a specific location, why can I not see the same content on Kindle Previewer and on my Kindle device?
A5. In a reflowable book, the content adapts to different screen sizes and font sizes. For example, as you change the font size on a device, the text you see in a given page might flow in to the next page. For the same reason, there might be differences between the content you see in a given location on KPR and on devices of different sizes. For fixed-layout books, given there is no reflow, the content you see in a specific location will match across devices of different sizes and on Kindle Previewer.
Q6. When I open my book on Kindle Previewer, some part of the content goes beyond the margins and is not visible.
A6. This could happen if you are using negative margins in your content. If that is the case, although the content is not visible on Kindle Previewer, when the book is rendered on a Kindle app or Kindle device, it will be displayed properly.
Q7. The zoom option on the Inspector window is not enabled for my book.
A7. The zoom functionality is used specifically for print replica books and will be disabled for other types of books. For books in other formats, if you wish to zoom into an image, you can double click on an image to open the image viewer and then double-click again to zoom-in.
Q8. Why can I not see thumbnails for my book when I open it in Kindle Previewer? 
A8. Thumbnail previews are currently available only for reflowable books that are enabled for Enhanced Typesetting. If your book is a fixed-layout book or is not supported for Enhanced Typesetting, you will see the previewer pane without thumbnails.
Q9. I get a warning with the message "App is not optimized for your Mac" when I launch Kindle Previewer 3 on my Apple computer. Is this a problem? 
A9. No. This is due to an update to Mac OS X, to warn users when they run a 32-bit application. Please download the latest 64-bit version of Kindle Previewer for Mac OS X from the ‘Downloads’ section on this page to avoid these warnings.
