[Pkg-kde-extras] Bug#711301: skanlite: Preview for Dithered and Lineart image types is corrupt on HP ScanJet 7400c

[Sean M. Pappalardo]

Package: skanlite
Version: 0.8-2
Severity: important

Dear Maintainer,
Skanlite as shipped in Wheezy shows corrupt preview images when lineart 
or dithered image types are selected. It looks as though the byte order 
is mixed up or the matrix is transposed because I see what should be an 
all-black area as a series of vertical black lines on a white field. 
This is on an HP ScanJet 7400C connected via USB.

The package in Squeeze worked fine with all image types.

    * What led up to the situation?
Upgraded from Squeeze to Wheezy.

    * What exactly did you do (or not do) that was effective (or
      ineffective)?
Changing to Grayscale or Color image types works fine. Making an 
arbitrary selection then scanning to a file despite the corrupt preview 
gives the expected output in the file. (It is just the on-screen preview 
that is corrupted, but therefore unusable since one cannot determine the 
correct selection area.)

I found a workaround: preview scan in grayscale, select the desired 
area, change to lineart or dithered, then scan the final. This isn't 
ideal though because the dimensions apparently differ between the modes. 
(I had to make the selection about 30% taller to get the desired area.)
