Page indexing error

Ivor_Shambling · 08-07-2014, 01:13 AM

Hi everyone

I have recently loaded a book onto my kobo glo and found that it is only showing up as a small image in the top right hand corner of the screen. Upon further investigation in Calibre I also found that the file was made up of a bunch of .png image files. This is usually fine with my e-reader but this time for some reason it was only detecting 2 pages for the entire book when there was a few hundred images. I have a feeling this causes the strange size of the page displayed but I am not too sure.

Essentially how can I designate one .png image to each page and then display the image in the full size on the kobo?

Any and all help would be appreciated

Convert to real text via OCR.

Or convert to CBR/CBZ (which is simply a rar/zip of the images). I think the Kobo Glo supports these formats?

Yes, all the Kobo devices support CBR/CBZ. And that sounds like the best format.

As to the problem, the missing pages usually mean there is an error in the code. A mismatched opening and closing tags can prevent the device from showing anything in the chapter after that point.

For the display of the images, chances are they are being displayed as the code says. If there are no sizing attributes in the image tags, I think they will be displayed at their correct size. I am reading a book that has an image at the start of each chapter. The code is:

Code:

<p>
  <img src="images/ffdl-07.jpg" class="pic-center">
</p>

and:

Code:

.pic-center {
  margin-left: auto;
  margin-right: auto;
  clear: both;
  display: block;
}

That centres the image on the page at its full size.

Auto margins give different results on different devices I think
