ePub to MOBI with Pictures

Bull06 · 06-23-2010, 10:23 PM

I am sorry if this question has been answered, but I cannot find it anywhere in the threads. I am using Adobe ID5 to create an ePub document that contains pictures. When I do the conversion to ePub with ID5, I have no problems with page layout. The pictures are jpg.

However, when I use Calibre to convert to MOBI, the pictures cause a page break before the text starts. Does anyone know what is going on? Thank you.

If the pictures are large then some mobi viewers will automatically put them on a screen by themselves. That's not a page break its just something that viewers do. Try a smaller picture and see.

When you say size, are you saying file size (kb vs mb) or pic size (pixel dimensions)? I have various sizes of both and all of them seem to do the same thing. Note also, I have viewed the MOBI file on both a Kindle and Kindle for PC and both seem to do the same thing. As for Kindle for PC, I can adjust the window and it still shows the same way. That is why I figure it is a "page break".

pixel size

Bull06 · 06-24-2010, 11:09 AM

Do you know the max pixel size or does it vary depending on the device?

kovidgoyal · 06-24-2010, 11:36 AM

It varies.

Thank you for the information. To let you know, I got all of them down to less than 200x200 pixels, but it did not work. I had originally had the picture above the title. However, when I switched the two (i.e. title on top), it worked with the original jpegs which were well over 500x500 each. Thanks again!

Hi!

I think I have found a problem (with Calibre 0.77, kindle, MacOS 10.6) when converting some (one?) letters from epub to mobi format.

Conversion
from to really should be:
"æ" "ae" "æ" (lower case)

("ø","Ø" conversion was fine)

These letter conversions are yet untested:
"Æ" (upper case)
"å" (lower case)
"Å" (upper case)

-

The front page image looked fine.

-

Test text:

epub was converted in the export process.
mobi was copied directly to Kindle and "æ" looked fine.

kind regards,

Glenn

check the keep ligatures option in conversion settings.

I am just starting using Calibre. It seems well done. I thank you (and other contributers) for it.

kind regards,

Glenn

Could you please consider by default not to do, the conversion of "æ,Æ" into "ae,AE" in Calibre in Danish, Norwegian, or Icelandic languages, or Old English (non-latin!) texts, because in these languages it is a distinct letter.

I found this to support it:

http://en.wikipedia.org/wiki/Typogra...g_as_ligatures
"...
The character Æ - lower case æ (in ancient times named æsc) when used in the Danish, Norwegian, or Icelandic languages, or Old English, is *not* a typographic ligature. It is a distinct letter—a vowel—and when alphabetised, is given a different place in the alphabetic order.
...
Æ comes from Medieval Latin, where it was an optional ligature in some words, for example, "Æneas". It is still found as a variant in English and French, but the trend has recently been towards printing the A and E separately.[7] Similarly, Œ and œ, while normally printed as ligatures in French, can be replaced by component letters if technical restrictions require it.
..."

Even though I have checked the keep ligatures option, "æ" still gets translated to "ae" in the news (mobi-format; epub format was apparently not generated).

By the way - the news system is at this time, the best bonus feature I have discovered since I got the ebook - thanks.

Will be fixed in next release.
