You may want to revise these lines in mobi2mobi:

        if ($len > 65535) {
            print "ERROR:    Record $id - Image data size definitely too large: $len\n";
        } else {
            if ($len > 61000) {
                print "WARNING:  Record $id - Image data size might be too large: $len\n";
            }
        }

I ran mobi2html on a nondrm book that I had bought online. It worked fine and I could open the html version on Firefox; it consisted of text mixed with jpg files of figures. However, I could not see any source code and when I opened the html with CoffeeCup editor, there were only two lines of text - long but not enough to cover over 200 pages of text.

Is there some way the author can hide the source code?

No. The "soure code" is the single HTML file. My guess is that the entire 200 pages are in the two lines you see, but the editor is truncating them.

Thanks for the info! I finally opened the html with MS Word and then looked at the source code and it all showed up. I was interested in precisely how the author formatted the book and how he use styles and css in general.

I'm working on an ebook and have done some simple html work before but haven't really used css, so I'm trying to learn by examples. The source code was useful because the author obviously hadn't used the overly complex automatic code generator results such as produced by MobiCreator for the html.

Mobipocket HTML is not a good way to learn CSS. Mobipocket formats flattens out all the CSS. I've found using Google to search for what I want to know helps. And then there is asking on MR as well.

As JSWolf says, MobiPocket Creator and mobigen.exe import a limited subset of HTML+CSS and produce a highly simplified HTML for the MOBI file. A better place to look for examples would be an ePub ebook. These can be "exploded" by renaming the .epub to .zip and unzipping. Another possiblity is Kindle Formatting: The Complete Guide. In fact, there is a DRM-free ePub version of the Kindle Formatting ebook, which might itself be a good example of ebook layout.

And adding the --imagemaxbytes option in mobi2mobi as well (for setting a large cover image).

I just added it to the subversion version. The mobi2mobi code is really starting to get ugly due to the incremental adding of features...

...and that's a good thing as it has steadily become much more useful!

Hopefully more useful. I did not bother to test the new code

What is the proper syntax in mobi2mobi to add in a cover image that does not get resized and replaces what is currently the cover image or the first image wich is not linked as a cover? Also, I'd like mobi2mobi to not recompress the cover. Thanks.

[Jellby]

I believe with the latest version you could use:

mobi2mobi input.prc --imagemaxbytes 9999999 --outfile output.prc

This version should not resize images by default anymore, and if the max-bytes is larger than the image size, it will not recompress it either. I don't think it replaces an image not linked as cover, though.

Sound plausible. You probably have to add the cover index first.

Can mobi2mobi be modified to remove the first image? And is there an windows exe of the version with --imagemaxbytes?

Well, probably not since the design decision for mobi2mobi it to not touch the content of the book. Just modify the headers and the images.

And is there an windows exe of the version with --imagemaxbytes?

Yes. Look at the web page.
