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

[alxwang]

Before the new release, If anyone need png file from lrf but want rename it:
CWD=`pwd`

find . -type d -print | while read direct
do
cd $direct
for file in [0-9]*.png
do
if [ ! -f "$file" ]; then
break
fi
bname=`basename $file .png`
nname=`printf %06d $bname`
mv $file $nname.png
done
cd $CWD
done

Or you can add one more param to let me give you what base font I installed for Chinese?
Then you can use the font I papered to create PDF.
For example:
-basefont "/usr/share/fonts/ttf/
fc-cache/msyh.ttf"

You can just create all font like:
BaseFont.createFont("/usr/share/fonts/ttf/
fc-cache/msyh.ttf", BaseFont.IDENTITY_H,BaseFont.NOT_EMBEDDED);

Thanks

Well, I only have had success using truetype collections. This new parameter is "-cfont filename.ttc f#", that chooses the font number f# from the collection. Using msgothic.ttc, f#=1 something is displayed on the pdf, but I do not know if it is correct...
I'm packaging new version now to upload.

New version v0.9.209
Added -cfont parameter for convertLRF, to choose font from a collection.
Now image names when converting to html are normalized (sorted)

ls-v0.9.209.jar convertLRF temp -d M:\AALC_TEMP\test\ -PDF -cfont msyh.ttf,f#=1

java.lang.ArrayIndexOutOfBoundsException: 7

Usage:
...
If I remove the "-cfont msyh.ttf,f#=1" no error but the PDF is still not correct - same as before.
Do I have to put the that ttf somewhere?

Any hint?
Thanks

You must use a TTC (truetype font collection), and correct command line is:

-cfont msgothic.ttc 1

I've not found any way to use msyh.ttf, sorry.

I've found a msdos tool (TTSDK) wich can create a ttc from several ttf's. And also I've check that msyh.ttf works this way (using 0 as index of font) for chinese lrf.

[alxwang]

It works with Chinese now. Really nice.
One more question: you embed the font in PDF or?
Thanks for this nice tool. Really useful.

According with iText documentation, only the subset of the font your document uses is embedded, not the whole font. This must be true, because the size of the resulting pdf is smaller than TTF file...

[alxwang]

Nice.
One more question: Is that possible to re-layout the text based LRF to other size. LRF is for 6 inch screen. Can LRFtool generate 10 inches PDF ?
Thanks

Hi, I'm having trouble using this program to convert from LRF to PDF
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?

[patricks]

Just tried it on the mac side,used "java -Xms200M -Xmx300M -jar LRFTools-v0-1.9.209.jar convertLRF cd /eBooks/ -EPUB"
and got the following error:

Are you sure you have the correct version of Java installed?

[patricks]

On the windows side I'm sure -1.6xxx (I used the java -version command from this thread).

On the mac side things seem to line up with what's available on the Apple java page:
JavaApplicationLauncher:
Version: 12.2.0
JavaScriptCore:
Version: 5525.26

But the thing that has really got me stumped is that I can convert the lrf file to EPUB, but I can't convert to PDF (as in I get the above error: "The name 'P103' has no local destination." and the pdf file that is created is corrupted).

Hi,
I am using LRFTools 0.9.209 to convert some lrf files to html. I found one minor problem:
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:

		</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.
