If you do just mobi2mobi on the input file what is the output? When you say it did not work does it mean that you got an error message or just that you did not see the image? If you do "mobi2html file.mobi unpackdir" is the coverimage then in the unpackdir?

If you send me the file I will test to add a cover image and fix eventual bugs. Send it in a private message here or visa email to tpe at ida.liu.se

Well, there is a bug in my code. Will fix it and fix some other bugs and make a new release during the weekend.

It is still fun

I found two bugs with your test example so a good test case. It is working now adding cover image. I will fix the author/image bug for files without an EXTH header tomorrow and then make a new release.

Two more bugs I've encountered:

1. lit2mobi crashes when saving .lit file: http://www.elkins.org/example1.lit

2. lit2mobi completes conversion, but book has no carriage returns or paragraph breaks: http://www.elkins.org/example2.lit

Both the original lit files seem fine using Microsoft Reader.

1. It does not crash for me. When I release the next version you can test it again and tell me if it crashes or not.

2. The problem is that Mobipocket does not support the <pre> tag. But I added my fix for that to lit2mobi so it look readable now.

Version 0.0.26 with Windows binaries is available from:

http://www.ida.liu.se/~tompe/mobiperl/

Changes in 0.0.26:

--prefixtitle now works for mobi2mobi and when input is a PalmDOC file.
Fixed bug with mobi2mobi and --coverimage. It did not work if the file did not contain any images.
Fixed rescaling bug. Now also images whose height is greater than 640 are rescaled. This is done because of a bug in the Gen3.
Fixed bug in mobi2mobi --fiximagesizes. In Linux the wrong tmp file was read.
Introduced a flag --gen3imagefix to mobi2mobi that can be used if you have a book that hang the Gen3. These kind of hangings are often caused by a large image in the book. This is a firmware bug in the Gen3.
Added call to fix_pre_tags in lit2mobi
Now it is possible to add author information to a Mobipocket file that does not have an EXTH.

Thanks for this update!

For me it still crashes on:

http://www.elkins.org/example1.lit
and
http://www.elkins.org/example3.lit

Both fail with a hard crash at /usr/local/bin/MobiPerl/Util.pm line 488

edit: http://www.elkins.org/example4.zip

Add coverimage fails:

Code:

mobi2mobi oldmobi.mobi --coverimage cover.jpg --outfile newmobi.mobi

When exploded, the coverimage .jpg has been included in the newmobi.mobi file

However, the globbed text seems to be corrected.

BTW, Think about setting up a paypal tip jar on your site. At the very least I'm sure you'll gain beer money...I know I owe you a case of your favorite

Aha, this is a bug I have not managed to track down since I did not have a test file. It is also a bug that only occur in Windows. So next time I boot Windows I will try to fix it using your test files.

There is one thing you could test. Could you test to rename the file to a name without ~ and change the name in the opf file and then run opf2mobi and see if it works?

Otherwise you could just remove the image files and the reference to them and run opf2mobi since the image files are not related to the book.

Sure, I'll test this today. Also, I don't run Windows. All my testing is done with Kubuntu 7.10

EDIT: Just tested. Removing the ~ has no effect. lit2mobi still crashes. However, editing the .opf file and removing image file references allows opf2mobi to complete.

Very good to know. It works for me using Debian unstable. Could it maybe be different versions of clit we are using? I use version 1.8.

The problem I think is that the reading of the file fails on line 486 in Util.pm. When that fails it tries to read it as a BMP file. But the file is a gif file with a jpg filename. So it should be read by "my $p = new GD::Image ("$filename");". What you could do is print out $filename at that point and confirm that it is the same as in the ctmp directory.

You could also write a simple perl script that just tries to read the problematic file and see if it works.

Since I do not manage to trigger this bug it is a bit hard for me to debug it...
