<A NAME="780619">19/06/1978</A><BR>

Hmm... but how do I create the opf file? Or better, what are opf files? (what is their format? are they text files? can they be easily created from HTML?) I'm using Linux, by the way, so Windows-only tools are of no use to me.

I assume the links works in the html file? You could try to use "a", "href" and "name" and see if it works.

opf files are documented on the MobiPocket web site. The contain meta information and pointers to the html files that te book consists of. Thinking about it a bit more I think it will work if you just put the guide thing in the correct place in the html file (the header). html2mobi should expand the links to a filepos and it should work.

Yes, the initial HTML file worked fine. I found the problem, though, it seems the links don't work when they are pure numbers, so I changed "780619" into "week0619" and now it's OK.

Thanks, I'll try that.

EDIT: Yes, it works if I add the <guide></guide> thing in the <head> section of the HTML file. Now the only thing missing, for the moment, is how the reader computes the location for the "Start Reading" link, since it doesn't seem to be defined anywhere.

I will do a new release in a couple of days. I have added possibility to set language and description and will add setting of subjects. I will probably also add an imageresize flag in spite of my opinion about this... Anything else simple I should add when I am looking at the code?

Concerning language setting. Now you can set all languages if you specify the number for it. I also have in my code:

Code:

my %langmap = ("en-us" => 0x0409,
               "sv"    => 0x041d,
               "fi"    => 0x000b,
               "en"    => 0x0009,
               "en-gb" => 0x0809);

If peole wanting to use this give me the line for your language I will add it here. Or give me a pointer to a list of this mapping. The ides was that the string is what is specified in the opf file.

Yeah, how about a simple usage message when no arguments are passed.

This is helpful when the perl code is compiled into a windows executable and you no longer have access (OK easy access) to the source code and documentation therein.

Nothing fancy, just straight forward command line syntax.

BTW, if you look at mobi2imp.pl, I went overboard there!

I don't know if this is the mapping you want, but it seems to fit with your list (except that "sv" is 0x001d and 0x041d is "sv-SE"):

Damn, you remembered

But that is writing documentation and not simple... I will add something.

Just a reminder that if you use an ordinary Perl program the standard way is to do "perldoc programname" to get the documentation and that works for MobiPerl also. But it does not work if you use the Windows binaries.

I have now added printout of usage if programs are started without arguments.

Verson 0.0.38 is available at

https://dev.mobileread.com/trac/mobiperl/

The actual release files are at

https://dev.mobileread.com/dist/tompe/mobiperl/

No Windows binaries for this version yet. Feel free to contribute them...

Changes in 0.0.38:

Added flag --description to mobi2mobi.
Added flag --language to mobi2mobi.
Read title from mbp file (not tested...) in mobi2mobi.
Unpack directory argument is now optional for mobi2html.
Added print of usage when programs are started without argument.
--imagerescale flag added to a mobi2mobi and *2mobi programs. Default is rescaling. To not rescale use "--imagerescale 0".
%langmap in MobiHeader.pm extended but it is still not compleat.
Added flag --subject to mobi2mobi. Currently only one subject can be set.

Here you are.

tompe · 04-27-2008, 09:24 AM

Thanks. Windows binaries also uploaded to dist directory.

Jad · 04-27-2008, 07:08 PM

Thanks for the great update Tommy. I'll look at adding the new flag options into the Mobi2Mobi GUI shortly.

Thank you also Gudy for the Win32 compile. Makes my life easier if the Perl & Win32 versions are available at the same time to keep the GUI in sync.

tompe · 04-27-2008, 09:12 PM

Remember that there can be more then one Subject in the EXTH. All are printed on the output. But the flag only change the first one.

Hi I've been trying to convert a pdf to mobi file using initially pdfread, this seems to hang after conversion to html. So i tried the html2mobi prog from the latest windows binary (0.38) and it begins to convert but hangs after a couple of images. When I resize the image by 1 or 2% and restart the process it continues and hangs a little further on.

The error message will be something like this: Could not shrink image file size for 66.png at mobiperl/Util.pm line 555. I should mention that i am using the -- imagerescale 0 option to try and get the best image for my iliad.

Any suggestions?

Jontom

JSWolf · 05-02-2008, 10:19 AM

Try converting the images to JPG and editing the HTML to reflect that they are now JPG and try again.

tompe, I'll take this one!

May I suggest that you create an empty file called 'debug' in the PDFRead install directory (usually C:\Program Files\PDFRead) and then try the conversion again. This time, at the end, the html and images used in making the .prc will be retained. I use a modified html2mobi (from version 0.37) that forces the 'imagerescale 0' option so as to get the largest possible images on the iLiad.

If you already have access to the resulting .html and .opf, then ignore the above.

Please post your .html and .opf files only here so that we can see if there is something going amiss with your conversion. Also, if you have any full-sized images (.png), what are their sizes generally? s/b 768x935!
