Description Brian Beck 2008-08-22 17:07:17 UTC
Version:           0.7 (using KDE 4.1.0)
OS:                Linux
Installed from:    Ubuntu Packages

If I open a CBR file the pages look "fat".  If I open that same file in QComicBook the pages look as they ought to.  I've attached a screenshot that should make it clear what I mean.

If I can help in any way let me know.

Rendering Comparison Between QComicBook and Okular

Notice how Okular seems to render the page a little too wide.

Do you have an example document showing the problem?
(If it cannot be shipped publically, you can send it to me directly.)

Hello Brian,

could you please provide a document?

Here's a link to a cbr file that shows the incorrect aspect ration in okular, but looks fine in QComicbook.

I looked up cbr on wikipedia to find out what exactly a cbr file was.  It is apparently a series of images in a rar archive.  I'm sure you were already aware of this.  So I decompressed the cbr file with unrar (UNRAR 3.71 beta 1 freeware Copyright (c) 1993-2007 Alexander Roshal), and displayed the first image in okular.  It looks fine.  I've taken a screenshot of the first page image file rendered by okular, and the first page of the cbr file rendered by okular to show the difference.  See Comment #5 (id=27174)

Thanks, the testcase was quite useful indeed.

The problems has been fixed:
- for KDE 4.1.2 (r855908)
- for KDE 4.2 (r855907)

Thanks for your report!
