Thanks

I'll take a look this weekend.

It works fine for EPUB with the following instructions:

java -Xms200M -Xmx300M -jar LRFTools-v0.9.209.jar convertLRF c:\eBooks -EPUB

But with PDF at the end it returns the error, "The name 'P103' has no local destination." And the pdf file it creates won't open in acrobat- "The file is damaged and could not be repaired." Other than replacing EPUB with PDF the lines are the same.
Can anyone point out what I'm doing wrong?

Well, this mean page 103 has no anchor destination. It's a bug. Could you pm a link for the lrf?

You must use a JVM 1.6 on Mac.

The generated html will break line automatically for italic font-style text.
You can see from my attached html file and screenshot.

I don't think it's the problem of LRFTools. It should be the problem of browser (I tried it with IE and Firefox).

I can fix this problem by manually removing:

Code:

		</div>
		<div align="Justify">

That's not an elegant way.

I am wondering if this problem might be fixed by LRFTools by properly detecting paragraph and insert <p> tag (or something else), so I raise this issue.
Due to copyright concern, I can't distribute this lrf file to public. If you do need one to analyze the problem, I will try to find a free lrf file with the same problem.

Added:
I roughly browsed several html files generated from lrf, there is a common problem: no paragraph tag. IMHO, adding paragraph tags will make a better conversion.

Fixed italic problem. I'm gong to publish new version tomorrow with this.
Why p tags? Actually DIV tag is used instead of P...

Uploaded new version 0.9.211. Check first post please.
BUGS:
Newline before italics and bolds.
Some improvements converting lrf to epub and html.

There is a command line argument (-A4) that do this.

This is some error log. The same lrf file, ok for v0.9.209, error for v0.9.211.
v0.9.211 does fix the break line problem. Thanx.

It seems that web browser and mobipocket reader will give additional line space to tag <p>, so there will be additional space between two paragraphs. For tag <div>, the line space between two paragraphs is just the same as common lines. That's why I want tag <p>.
Maybe it can be done by inserting addition attribute in <div>, but I don't know how.

Just tried the newer LRFTools_gui on my linux box. Running Java 1.6.0_10.

Hangs, I'm afraid...

The old version still launches fine.

Any suggestions?

A4 Parameter works really well.
Thanks again.

-rf a percentage of resistance to change size of font .
What's that mean? Can I use this one to increase font size?
Thanks.

It's difficult for me to explain -rf. I've been collecting books taht seems to be 'scanned' and 'OCR-ed', resulting in a reasonable quality but with one problem: small and unnecessary changes of font sizes on the same paragraph.
This is odd. (-rf number) parameter works this way:

When on a paragraph the font size is changed from size 'a' to size 'b'; if this parameter is specified and 'b' is greather or lower than (1+number%)*a, then the size is changed; otherwise the size of the font is not changed.

So, no, you cannot use this param to change font size, but this would not be difficult...

Cool.
The A4 reflow works really well but if I can set a "% of font size increase" it will be even more useful. It tells how much I want the font come to bigger like 120%. It is not new font size.
Thanks.

One more question:
I compare the png result and PDF result and I found out the picture quality decreased a lot in PDF compare to png. How can I prevent that happen?
Thanks.

First off, thanks for the great tool -- I've been using it for a while now with great success!

Today I tried using 0.9.211 to convert a pdf to epub (this particular file works in calibre but formats poorly), but java appears to be throwing an exception on this file 411 pages in:

Code:

Other PDF (and lrf) files I've tried work fine; it may be something particular to this file. Although the zip exception is odd....
