Well, actually these HTML files are not even close to 16MB. More like 600KB. Very well structured HTML, autogenned from FB2...

In fact, the Sony Reader happily takes huge image-based LRFs, and has no problem displaying them. I've tried as large as 37MB, and they worked very well. Compared to the PDF viewer, the LRF viewer in the Reader has been debugged the hell out of, I guess.

Here's an updated version which can decompile it.
Also updated lrs2lrf which sets the specific scramble key (0xFE00) checked by LRFCreator.dll.

igorsk, nice work! Working well for me with the Gutenberg HTML books but some of the later ones (e.g. Etext 19694) crash HTML2LRF .
I've looked at the DesignHorizontal.lrs (decompiled with lrf2lrs) but haven't got a clue what it means. Is there anyway to force page breaks in the LRF from the HTML pages?

Best would be to split it into separate HTML files. This way you'll also get a bonus in the form of TOC entries.

igorsk - Fantastic script! It's exactly what i've been searching for since i got the ebook. I've been writing perl scripts to scrap online mags/blogs all over the place and use your script to convert them, then do a daily sync to the reader. Seems to be working great. Thanks a bunch!!!

scotty1024 - been die'n to try out your prog, but it's been a while since i've dived into java. It looks like i'm missing some libs (when i executed the program). Do i need to download those 2 libs you mentioned in order to get it to work?

It uses a couple public java libraries: xpp3 and jpedal.

It can re-flow HTML and PDF documents into LRF files. It has latent support for rasterizing PDF files into PNG's in the LRF (non-reflow).

It comes with a sample Creative Commons ebook to bind with it: Cory Doctorow's Someone Comes to Town, Someone Leaves Town.

I've GPL'd the tool (not Cory's book), have fun.

Hi Scotty,

I'm curious to try your BBeBook program but I've got zero Java skills. A friend suggests you might have a batch file that compiles or starts the program. Or perhaps a readme file.

Do you?

Thanks!

igorsk, I've written some perl wrapper scripts to feed HTML books into your HTML2LRF, mostly for Gutenberg HTML books, the thread is here

Is there anyway to stop HTML2LRF from generating the front title page?

Also when running HTML2LRF you have to be in its directory for it to work otherwise it cannot find the DesignHorizontal.lrf file, noticed some code in the HTML2LRF.cpp to handle this but then later it is ignored and just looks in the current directory.

[igorsk]

As far as I can see, addition of the title page is hardcoded in LBParser.dll. LRFCreator.dll gives more flexibility but you'd have to do a lot of manual work, like parsing the HTML...
And thanks for noticing the bug, I'll fix it.

[QUOTE=igorsk]

Usage:
HTML2LRF [-t "Book title"] [-a "Book Author"] [-o output_filename] <url|path.html> [<url|path.html>...]
Defaults are "Test Book", "Unknown Author", and "test.lrf".


Can somebody please tell me how to format the command exactly if I have:

A book ready at: C:\Documents and Settings\Bobby\Desktop\Cell.html

The program is here: C:\Documents and Settings\Bobby\Desktop\HTML2LRF\bin\

Thanks!


I tried to do it but I get a runtime error:

[igorsk]

Something like this should work:
c:
cd "C:\Documents and Settings\Bobby\Desktop\HTML2LRF\bin\"
HTML2LRF "C:\Documents and Settings\Bobby\Desktop\Cell.html"

Thanks igorsk but I still get the runtime error. Will try it on another laptop tomorrow.

Then I guess it could be something to do with the HTML file... how big is it?

[diabloNL]

It's 0.8Mb. I tried different files all around the same file size.

That's too big for HTMl2LRF to handle. Use my splitbook.pl here to split it on Chapters.

[diabloNL]

Thanks FangornUK! I will give it a try.

EDIT: It works! Only thing is that I would like to adjust the margins and textsize but the DesignHorizontal.lrf/lrs doesn't make sense to me what I need to change.

Man, if only Sony would enable pictures in RTF.
