bd2mobi - Application to convert Book Designer html0 to .mobi

[maggotb0y]

I've written a perl script to convert .html0 files output by Book Designer to .mobi format for viewing on the Kindle or other .mobi devices. This should be useful to those of us who would like to (legally, of course) share our content with Kindle owners.

This will automatically generate the table of contents from the "Titles" in the original BD file.

I've attached a zip file with a compiled .exe file, and the Perl source for this file for anyone who'd like to contribute. You'll need to extract the .exe and download mobigen from Mobipocket (available at http://www.mobipocket.com/dev/)

The easiest way to use this is to create a shortcut to the .exe in your "Send To" folder. Then you can simply right click on any .html0 file and choose Send To>bd2mobi, and it will convert the file for you.

Let me know how it works for you!

p.s.- Thanks to HarryT for the excellent tutorial that I followed in creating this script.

version 2 now attached
This version now properly converts books with PNGs and GIFs in the source.
version 3 now attached
This version works properly with newer versions of mobigen and allows you to specify author, title and cover image.

Uhm. BD creates books for Kindle or CyBook Gen3 or Iliad without any additional tools. Why would you write another tool for the purpose?

I'm not aware of a way to generate .mobi files from BD. There is a PRC (or perhaps PDB, don't have it in front of me at the moment) option, but that has never worked properly for me. Is that what you are referring to?

Doing research on the topic, I found HarryT's thread https://www.mobileread.com/forums/showthread.php?t=17914 and automated the process.

I was under the impression that BD can create mobi pocket books. Because Harry_T creates his books in BD. I was aware about TOC problems. I see why you wanted to automate the process.

Thanks.

It cannot create true MobiPocket books. It can pack HTML in a PalmDOC book that can be read by MobiPocket readers. But you need a true MobiPocket book if you want to have long titles and meta information like author. Also BD does not work on all platforms.

My MobiPerl contains opf2mobi which generated true MobiPocket books.

You're welcome to grab this code for inclusion in mobiperl - it basically automatically creates a table of contents and an OPF directly from the HTML0 file, then calls mobigen to build the .mobi file, finally deleting the files it creates for the conversion.

I put it on the list of possible things to do. I thought about it a couple of days ago but then decided that since HTML0 is a Windows specific format in the sence that the only tool that generates it runs only in Windows it was less interesting to do it.

As motivation, html2lrf has a BD preprocessor

The "MobiPocket" books that BD creates are very poor. They don't have any metadata, all text which should be centred comes out left-aligned, all pictures come out very small, the navigation links to the table of contents don't work - there are numerous problems.

It's a lot better to use BD as a book editor, but then to use the "Mobigen" or "MobiPocket Creator" tools to create a "proper" Mobipocket book. That's what I do now, and what this thread is all about.

I see.

WOW I am a little bit surprised and disappointed

When I was doing a research on iRex iLiad, I have asked a couple of times whether creating books for iRex iLiad would be more difficult or different than creating lrf files for Sony in BD and whether they would be of the same quality and as nice looking as lrf files. Besides pointing out to me that I will have to "manually" (use a certain command in BD) add TOC in the beginning of a book and that pics will be smaller, noone has mentioned all the problems that I hear now.

Does BD2Mobi create a proper table of contents and proper metadata?

Also, how does an eBook created using bd2mobi compare to doing it using Harry's tutorial?

[maggotb0y]

BD2Mobi reads the "titles" from the BD html0 file to generate the table of contents, and extracts the Author and Title of the book as well.

bd2mobi does exactly what HarryT's tutorial walks you through- it just automates it all. The only thing it does not automate is converting any non-jpeg images to jpeg. If it sees any gifs or pngs in the source, it will let you know that you need to fix that.

Sounds good. What version of Perl would I need for Windows in order to use your program?

[RWood]

vvv has stated that the BD output for mobi is several versions behind the current mobi level. It is one of the items on his enhancement list which itself has no publicly released milestone dates -- it may be released this week, it may be released in a year or more.

When we first released mobi books (with the PRC extension) there were only a few takers as the iLiad had just acquired the ability to read them. With the release of the Gen3 and now the Kindle the number of downloads for mobi books has grown. For most books the number of downloads for mobi is still below that of Sony but the gap is closing and for a few the mobi is format is more popular than the Sony.

For the compiled version, you won't need Perl at all, just run the .exe.

If you want to modify the Perl script, you should be able to do this in just about any version of Perl- it isn't doing anything particularly fancy.
