Hey, I've been using Book Designer for a while to create Sony Reader Content, and I think it's a nice program, but it looks like I'll get better results with html2lrf for inline graphics and tables, etc. I'd like to be able to convert my HTML0 files output by BD using libprs500, and I'm having a few problems. I've looked around and was a bit surprised that this doesn't seem to have come up on the forum.

Here are my questions.

I can't figure out a chapter-regex that will pick up BD style chapter tags (I've included an example below). Can anyone help me with that?

<SPAN id=title><DIV align=center><B><FONT color=#001950>PROLOGUE</FONT></B></DIV>
</SPAN>

Another issue is trying to get page breaks to work the way I want. BD replaces the <HR> tag with page breaks, and I use that to control pagination (BD by default also does chapter page breaks, but I turn that off so that I can have more control over the output). With libprs500, I can use page-break-before-tag=HR and that controls the page break fine, but it displays the Horizontal Rule, which I don't want. Is there any workaround that would create the manual page break, but not include the visible line?

Finally (for now at least), BD creates empty lines as
<DIV align=justify>    </DIV>
and HTML2LRF seems to not respect that empty line- the line below is pushed up. Is there any way I can force this to show as an empty line.

Hmm none of those issues have easy solutions. What I will do is make a preprocessing option for BD that will automatically replace the problematic html with HTML that html2lrf processes. Can you send me a couple of example HTML0 files.

Also you may try saving the HTML0 files as HTML in BD and then running html2lrf over them.

A pre-processing engine for BD would probably make quite a bit of sense. The only difference between the "html0" file and the "save as HTML" options in BD is the name of the extension <g>.

I've attached a zip file with an HTML file generated from BD that will give you the basics. I'm sure it is pretty self explanatory, but if you have any questions, let me know. If you need some bigger files for a more complete test, let me know and I will see if I have anything public domain with some good formatting to post.

Hmm tell me if the following mapping is correct
<span id=title> --> <h1>
<span id=subtitle> --> <h2>
What about lower levels of headings? subsubtitle, etc?
That way you can match chapters on either h1 or h2.

<hr> --> <span style="page-break-after:always" />

I will probably modify html2lrf's handling of the div tag to take care of the blank lines.

Incidentally, the way BD uses the id attribute is puzzling. According to the HTML spec ids should be unique, is there some reason vvv chose to use the id attribute rather than the class attribute, which is a much more natural fit?

Looks almost right- book designer always creates a chapter for <span id=title> and never creates one for <span id=subtitle>. I use this to create a title for (e.g. "A funny thing happened today") but not for the subtitle ("chapter one") so that I have control over what appears in the table of contents. I doubt you would have to do much special handling for span id=subtitle, they will probably take care of themselves just fine.

Not really sure why BD is the way it is <g>. It's a nice enough tool for creating ebooks, but it has it's quirks, and the pace of development and featureset of libprs500 seems to far outstrip BD (which is why I would like to make the switch).

Thanks a lot for your work on this, I'm sure you'll earn quite a few converts. Let me know when you have something ready for testing- I'm excited to start running my collection through this!

If anyone wants to donate to get kividgoyal a new 505 so he can port libprs500 to it then please have a look at https://www.mobileread.com/forums/showthread.php?t=14496 and give give give.

I've been trying for a couple weeks to get a website page to lrf format using libprs500 in Linux (ubuntu). The page is simply a text handbook, so I thought it would be simple.

Well it hasn't really worked for me yet. i've tried saving html converting to pdf then pdf2lrf, no go. Tried html2lrf, again no good.

Could somebody convert show me how to convert this page :
http://www.gentoo.org/doc/en/handboo...l=1#book_part1

Then let me know how you did it.

Thanks,

kovidgoyal · 10-05-2007, 07:17 AM

When you say no good, what do you mean exactly? The simplest way to convert an online website into an LRF file is

web2lrf --url "http://www.gentoo.org/doc/en/handboo...l=1#book_part1"

EDIT: In your case the correct commandline is web2lrf --url "http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?style=printable&full=1#book_part1" -r 0

glenn69 · 10-05-2007, 04:10 PM

I'm sorry for the lack of detail with "no good," but I've tried so many times that I've forgotten exact problems.

I ran the command exactly as you suggested
web2lrf --url "http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?style=printable&full=1#book_part1" -r 0

When I try to view in Sony reader, upon opening the file, it either hangs on "Formatting..." or it reboots the unit.

So,I tried to use lrfviewer to view the created lrf. Below are my errors upon viewing:

Thanks for help and all your efforts on this great project.

This is because the PyQt on your distribution is not correctly installed. The LRF file should work fine if you copy it to the SONY reader or view it using the Connect software.

Added initial support for pre-processing via the --book-designer option in svn.

According to Synaptic I have the following pyqt's installed:

Python-qt3
Python-qt4
Python-qt4-dev
Python-qt4-gl
Python-qt4-sql

Is there something else I need ?

kovidgoyal · 10-05-2007, 11:12 PM

It's a version problem. You should either install SPI and PyQt by hand or wait for gutsy.
