This program is based on fb2conv program published by dnkorpushov on the-ebook.org site.

Original program (being Python 2) did not work well under Windows when non-russian system codepage was selected for non-Unicode programs. In order to improve the situation I had to port it to Python 3. Later author of original converter re-joined the project and ported GUI UI here. He also added binary releases for MAC.

Here is brief list of changes to the original project (in addition to bug fixes):

• All messages and profile descriptions got translated to English
• Fixed all problems I was aware of at the moment (see git log)
• Added ability to apply xslt transformation from external file to fb2 before further processing (--xslt key or <xslt> config tag)
• Added xslt extension "katz_tr" to speedup and simplify transformation of direct speech in dialogs
• Added smart dropcaps processing (--dropcaps=Smart key or <dropcaps>Smart</dropcaps> config tag)
• Added some rudimentary epub processing (like title rewriting based on calibre metadata and hyphenation)
• Switched hyphenator to hyphen which uses properly maintained dictionaries from LibreOffice, so now many languages are supported and you could add more
• Added support for "floating" footnotes (--notes-mode=float key or <notesMode>float</notesMode> config tag)
• Added support for MOBI post-processing and optimization
• Added cover and thumbnail image optimization
• Made cover size user configurable (--screen-width, --screen-height or <screenWidth>, <screenHeight>)
• Added support for latest Kidle firmware (>= 5.7.2)
• Added simple tool to generate thumbnails on Kindle devices
• Added synchronous logging to file and console (console logging level is set independently by --console-level key or <consoleLevel> config tag)
• Added an option to make PNG images non-transparent to prevent "ghostly images" on Kindle (--remove-png-transparency key or <removePngTransparency> config tag)
• Added support for auto-generation of PageMaps - now it is possible to have APNX files (--apnx=eInk|PC key or <generateAPNX> profile tag). Number of uncompessed text characters per page is (approximately) controlled by charactersPerPage profile tag and by default is equal to 2300 (Calibre default setting)
• Removed <flatTOC> support. New config tag <tocType> and command line parameter --toc-type could be used instead with values Flat|Kindle|Normal. This introduces special support for eInk Kindle devices with 2-level TOC views. Additional tag <tocKindleLevel> and parameter --toc-kindle-level allow for precise tuning of generated NCX for eInk devices.
• Expanded book title generation: added #padnumber to generate number in series padded with zeros (use <seriesPositions> or --series-positions to specify how many digits overall will be generated) and #date to add proper date from <title-info> if availabe.
• Added new <chapterLevel> configuration tag and ---chapter-level parameter along with new style .titleblock_nobreak. When parsing sections this style will be generated if nesting level is greater or equal to specified value. This allows better control of page breaks on sections boundaries.
• Supported <openBookFromCover> configuration tag and ---open-book-from-cover parameter for compatibility with fb2conv.
• Changed how book title and book author are formatted - added processing of conditional blocks, for example: <bookTitleFormat>{(#abbrseries{ #padnumber}) }#title</bookTitleFormat>. To output curly braces escape them with backslash.
• Added new css style .linkanchor - this is style for all href links which are NOT pointing to the note bodies. This allows for flexible formatting of hyperlinks in the text.
• Added "default" cover for fb2 which do not have it (APG 2018.1) - <coverDefault> in profile configuration.
• Added cover "stamping" with book title, series and author name(s) - <coverFont> and <coverStamp> in profile configuration or --stamp-cover on command line.

Program uses source code (modified) from following projects released under GPL:

• KindleUnpack
• Image Utils

In order to build releases we are using Python 3.6.3 with following modules.

If you are not using "frozen" distribution you would need to download Amazon's KindleGen.

Enjoy!
