To have the flexibility of designing your content entirely outside of Kotobee Author using tools such as Adobe InDesign or Microsoft Office, the PDF import function may come in handy. This will import the contents of your PDF and distribute them among chapters of your ebook in Kotobee Author. PDF Import is supported on Windows and Mac. To access the PDF Import dialog box, select the File menu, click on Import From, and select PDF. PDF import comes in three modes: Editable content, Accurate & selectable, and Plain text. Each page of the PDF is made into an ebook chapter by itself, set to fixed-layout. This means that there is no word-wrapping and each element on the page has a fixed position. For more information, on fixed layouts and reflowable layouts, read Understanding reflowable / fixed layout modes.


Editable content

With this mode, your PDF is converted entirely into HTML5 format, with embedded fonts and images extracted from the PDF. This produces an accurate copy of the PDF, but not always. In some cases there can be words shifted slightly, or even characters missing due to complexity with fonts. The conversion process is complex, and the HTML produced has many elements, to replicate the PDF as much as possible.

Accurate & selectable

This mode converts each PDF page into a bitmap image, that is 100% guaranteed as an accurate replicate of the PDF. Optionally, you may choose to have the text selectable. This is done by generating an HTML layer containing invisible text on top of each image. The user will be able to highlight and copy text. Additionally, searching is made possible throughout the PDF.

Extract Text

Import text from the PDF into the chapter. The text is imported as raw text excluding any formatting, all into a single chapter. This is the only mode where the chapter remains in reflowable layout. Therefore, the ebook users will be able to adjust the text size and have the text wrap according to the screen dimensions.

Here are the different options available, when importing a PDF.

Page range
Choose to extract a range of pages instead of the entire PDF file.
Allow for better encoding. If the PDF file has bad encoding, this option may cause losing character. For difficulty making an accurate conversion, try this option on and off.
Page offset
Shift the chapter numbering by a certain offset. This will not affect the page range of the converted PDF, but only the naming of the chapters. By default the page offset is zero.
Image type
The image type of page scans. GIF (recommended) takes more generation time but smaller file size. PNG takes less generation time but larger file size.
Image quality
The image quality of page scans. Range from 0 (lowest quality) to 100 (highest quality).
Selectable text
When using image scans (Accurate & selectable mode), you can optionally allow the text to be selectable, by making an invisible HTML layer above the image. This will enable text-reliant features such as search, copying to clipboard, highlighting, note-taking, etc.
For PDF files which contain right-to-left content (e.g. Arabic, or Hebrew), this option will adjust the layout to allow right-to-left selections and have correct meaningful sentences. This option is available only for the Accurate & selectable mode.
Chapter pattern
Each converted page from the PDF will have its own dedicated chapter in your ebook. The chapter pattern allows you to specify the automatic chapter naming to be used. The letters [no] in the pattern gets replaced with the page number. So if you specify a chapter pattern like "Page ([no])", you will find your chapters named as: Page (1), Page (2), Page (3), etc.
Parent chapter
You may optionally have all the converted pages added as subchapters of an existing chapter. in your book By default, the root is selected, such that the newly created chapters will be main chapters with no parent.

After selecting your PDF file, click on Create. The importing process may take some time, depending on the size and complexity of the PDF.
