LRFTools. Convert LRF to EPUB, HTML, PDF and RTF

Another tool, credits to scotty1024 (LRFParse.java), Bruno Lowagie (iText) and people at apache jakarta project, xHTMLRenderer project and others right now I cannot remember.

It can convert LRF files to RTF, PDF, HTML and EPUB. Also can merge LRF and PDF books in one big PDF with TOC, and merge EPUB files into one. And now you can view epub files (use page and key down/up).

You can convert PDFs to EPUB using this tool.
And starting at version 0.9.193, you can conver MS Word 2007 (docx) files to EPUB
v0.9.204 can deal with all scrambled and/or compressed streams

New version 0.9.236 use latest versions of pdfbox, iText and some other libs. For devs: LRFTools is now a Maven project.

Usage:

Sounds great - does it preserve formatting and images and all?

I'm unlucky...

Put the book in a dir called "a". Here's the output:

Code:
Error occurred during initialization of VM
Incompatible minimum and maximum heap sizes specified
Any suggestion?

I had the same, but removing the "-Xms100M" part solved that - I don't know what it is for? Something for allocating heap size?

As for images, it looks like they are preserved! Yay!

Some of the formatting looked a bit weird in PDF but links work, the formatting looks better in RTF but I lost the links.

Great effort! This totally should be a sticky post.

Wow, you ARE unlucky. I tried this on my corporate XP box.

Commandline: java -jar LRFTools.jar convert d:\export -RTF
Where D:\export contained the lrfs (a single one to test, actually)

java version "1.6.0_01"
Java(TM) SE Runtime Environment (build 1.6.0_01-b06)
Java HotSpot(TM) Client VM (build 1.6.0_01-b06, mixed mode, sharing)

So what command line and java version for you?

Yes, I must say you need a java VM version 1.6, and append also -Xmx100M. I'm going to edit initial post to reflect this.

Yes, it supports PNG, GIF, BMP and JPG both to PDF and RTF. I have try to conserve formatting, but sometimes with books created with some tools tends to create one paragrap per line, and then the conversions try to emit a new Paragraph for each line. I've try to 'concatenate' these, there is a program parameter to do this (Beta) : -catpar. So if you try:

java -jar LRFTools.jar convert dir -PDF -RTF -catpar

LRFTools try to concatenate these lines, but this is not always the best formatting...

Hmmm, I attached two examples. The source file for conversion to lrf was plain HTML, no special formatting. The de-converted rtf file looks great, but the line spacing on the PDF goes wonky in places. See the attached examples.

I will reiterate, great tool - many many thanks.

I'm trying it with no luck so far.
Running java -version, results in:
Java(TM) SE Runtime Environment (build 1.6.0_07_b06)
Java HotSpot(TM) Client VM (Build 10.0-b23, mixed mode, sharing)

Trying to run the command:
java -Xms100M -Xmx100M -jar LRFTools.jar convert h:\ebook Conversion\lrftools -RTF

trying to get just an rtf output for a single lrf (Trumpet-Major.lrf) in the directory results in:

java.lang.NullPointerException
at lrf.parse.ResurseDirs.convertAction(RecurseDirs.ja va:186)
at lrf.parse.ResurseDirs.(init)(RecurseDirs.java:108)
at lrf.parse.ResurseDirs.main(RecurseDirs.java:33)

Since I'm not a java-phile, I have no idea where to go from here. Any help out there?

Thanks,
Gene
