Mobi to Epub Conversion Small Font Won't Enlarge

jamezgatsby · 08-04-2013, 11:54 AM

So I just purchased a Nook HD+ and since I'm not a big fan of the Kindle android app I wanted to convert all of my kindle books using Calibre and upload them to my Google Play library. I was able to convert all of them perfectly except for one book in which the font conversion is very small and it won't enlarge no matter what I've tried.

I've searched a few post but still haven't been able to get the font to enlarge after conversion. Check out the pictures below, please help!

What am I doing wrong?

It appears that you are trying to use the setting in Preferences.
That is the DEFAULT used for the first time converting a new book. Changes there do not affect previously converted books.

Use the (similar) form that comes up Initially when starting a convert. That applies to the current book and reflects the previous settings.

Note: there is a button (tick box in bulk mode) to cause the existing setting to be discarded and load the current Defaults.

Thanks for the input,

I followed your instructions and for some reason it still converted the same exact way much smaller font sizes than all of my previous ebooks that converted just fine. I'm not sure if it's a bug or something that i'm still doing wrong

See https://www.mobileread.com/forums/sho...d.php?t=186697

Most likely the book in question has scanned page images not actual text, but it's impossible to say more without access to the book.

(detective work)
Select Book: Tap T: Click Explode book.

Now look in (open) the OEBPS folder:
Now do the same with the Images Folder.

How many files are there?
If 53 or More (at least one per HTML file) , open a few. Are they pictures of a page?

You can close all the file browser windows and CANCEL the Tweak Book Dialog

Thanks,

1. I don't have a OEBPS folder, the only folders I have are images, META-INF and text folders

2. In the images folder there are more than 53, no pictures of a page

3. In the text folder there are html files listed as "part0000-part0070"

Thanks for your help

That structure sounds valid. I am just used to Sigils style, that I forgot that there are others.

Well it was a shot, you were supposed to have lots of HTML files (looking at the log)
I was thinking they were just (small)containers for a (page) img link.

Since you did not see Images of pages, that rules that out and rules a strange coding IN

Nothing less than total reverse engineering will fix that mess

I suspect that the font sizes are hard coded into the html. Delete everything but the original azw3 source file then reconvert using default values and check disable font size rescaling. Then manually edit the css using tweak book or sigil.

I have the CSS files open but clueless on how to edit it can you give me a idea of what I need to do?

Thx in advance

I think what is trying to be conveyed is the font code is IN the HTML, and not the CSS (or weirder, both) and the INLINE style overrides the CSS

That is what I meant.
In the stylesheet.css you will be looking for: font-size: **; see bold in sample css

Code:

.calibre1 {
    display: block;
    font-size: 12pt;
    margin-bottom: 0;
    margin-left: 0;
    margin-right: 0;
    margin-top: 0;
    text-align: center;
    text-indent: 1.5em
    }

Change all of the font-size elements to /*font-size: **;*/ to comment out the font size. Save then check using Preview Book, if nothing change then the font size is hardcoded into the html, if that is the case then use Sigil to edit the html.

Code:

.calibre1 {
    display: block;
    /*font-size: 12pt;*/
    margin-bottom: 0;
    margin-left: 0;
    margin-right: 0;
    margin-top: 0;
    text-align: center;
    text-indent: 1.5em
    }

Hi there,

I recently had the same issue with a book that had been converted from MOBI to EPUB using calibre -- i.e., Google Play Books would display the converted book with teeny-tiny text and would not let me resize the text.

I opened the converted book with Sigil and found that each "part", i.e., each individual HTML file within the epub, had a line specifying the font-size using "rem". I couldn't find anything in the epub that specified the original, i.e., the "root", font-size.

The problem went away when I did a bulk find/replace for "rem" with "em."

I don't know if this is a problem with Google Play Books, calibre, or the settings used when doing the conversion in calibre. If one of you tells me that it's a problem with GPB, then I'll go ahead and open a ticket with them. If it's a conversion settings problem, I'd appreciate any advice you may have on fixing it. If it's a problem with the conversion itself, it seems like it would be easy enough to fix.

Thanks for your help.

Presumably Google Play Books has no support for the rem font size unit. I could probably have the calibre conversion convert it to some other unit, but I'd need a sample file.
