one particular pdf document blurred on kindle

ihateusernames · 01-06-2016, 01:18 PM

When I try to open this document on my kindle 5th generation it only shows the first page correctly, the other pages are either blurred or blank. Usually they're blurred when it's in portrait orientation and blank when it's in landscape orientation. I don't have this problem with other pdfs.

This is the document:

https://archive.org/download/passing...00granuoft.pdf

How do I solve this?

What about you? Can you open the document in your device? Does it show properly, if you scroll down a few pages?

This PDF has all images stored in "JPX" format, which compresses very well, but which the kindle probably can't handle. You can run it through k2pdfopt to convert the images to PNG. The output file will be much larger than the source, but it will be readable and will be more responsive:

Code:

k2pdfopt -mode copy -cbox 0.5in,0.2in,4.2in,7.1in -cmax 2 -c- file.pdf

The -cbox option crops the pages to fit better to your kindle screen without all the extra margins.

PS. You can see the format of the images in the source by clicking the "INFO" button in k2pdfopt, or by "k2pdfopt -i file.pdf".
