LRF output

kovidgoyal · 04-26-2007, 12:20 PM

I'm happy to announce html2lrf, an open source, cross-platform HTML to LRF converter that I believe is the most feature-complete converter available. It's distributed as part of libprs500 and will eventually be integrated into its GUI. I've attached an LRF file to show off some of its capabilities.

It has support for CSS, recursive links, inline images, lists, tables, dropcaps and embedded fonts.

If you have an HTML file it chokes on, I want to know about it!

For all you content creators, this presents an alternative content creation path. Just open the source file in you favorite office suite, save it as HTML and run it through html2lrf.

Get it and the rest of libprs500 from https://libprs500.kovidgoyal.net. After installation a command html2lrf will be available. It's self documenting, i.e. just run it to get a list of options. Basic usage is as simple as

Code:

html2lrf myfile.html

I should thank Falstaff for pylrs and esperanc for the initial CSS conversion code.

Congratulations... so you finally released it!

I just looked at the code, and it's written very nicely.

Thanks now I have to build the GUI and integrate PDFRead and I'll release libprs500 0.4. So much to do, so little time ;-)

Now that PDFRead is almost feature-complete (can't think of anything more to add)

I plan to look into adding more device backends to libprs500 like we discussed.

BTW, I think you should do a strategic renaming of libprs500 ... now it does so much more.

Cool adding more devices is a most welcome feature.
Yeah, but I haven't been able to think of a good name. Any suggestions. Also I think I'll wait until it's a little closer to maturity.

BTW, you might want to change your Feisty installation instructions: there's no libusb package, but libusb-0.1-4.

Nice work! My first converted book looked very nice with one exception.

The first page was blank except for the following line:

Code:

xml version='1.0' encoding='%SOUP-ENCODING%'

Any ideas why this might be?

BTW I'm running the Windows version of teh html2ltf app.

Thanks, done.

Send me the HTML file that looks like an xml declaration.

AndyQ · 04-26-2007, 01:14 PM

I've just found out why.

The HTML file for some reason had the following xml declaration at the top:
<?xml version="1.0" encoding="UTF-8" ?>

Removing this causes the html file to be converted fine (without the funny front page).

Whether you want to cater for this oddity I'm not sure (its not really common although all browsers handle it OK)

Two more packages are also needed: python-qt4-gl python-qt4-sql.

BTW, was looking at the code and looks like it may take some time for me to implement it: The Device interface is not used anywhere, but the PRS500 class is. However, the Device interface is very do-able for the REB1100. For the 1150/1200, you can't really do anything: the whole interface is controlled by the ebook itself, with request coming to a webserver. It *might* be possible to host this in prs500, but I don't think you'd be very interested in it...

Fixed in svn

Thanks again. Basically if you implement the Device interface I'll take care of the refactoring of the code to only depend on it. There are some additional constants you may have to define that I'll let you know about later. As for the 1150/1200 its up to you, if you're willing to make it work, I'm happy to help as much as I can.

This sounds fantastic, but pardon my ignorance. I've downloaded and installed libprs500 but don't see any html2lrf anywhere in the program, not did I see it as a component during the installation. TIA.

It's a commandline program which resides in the libprs500 folder.
