           Summary: Needs PDF image smoothing
           Product: okular
           Version: 0.12.2
          Platform: Debian unstable
        OS/Version: Linux
            Status: NEW
          Severity: wishlist
          Priority: NOR
         Component: PDF backend
        AssignedTo: okular-devel at kde.org
        ReportedBy: christopher.martin at utoronto.ca


Version:           0.12.2 (using KDE 4.6.3) 
OS:                Linux

Adobe Reader uses some sort of filtering on images embedded in PDFs to smooth
them, so that as the user zooms up and down, they look reasonable.

In Okular, by contrast, embedded images (presumably bitmap formats) look
pixelated, which is unattractive and can also make it hard to discern details.
Some sort of image smoothing would thus be a welcome feature that would bring
Okular closer to parity with Adobe Reader.

Thanks.

Reproducible: Always

Steps to Reproduce:
View a PDF in Okular that contains embedded images (probably bitmap format
images).

Actual Results:  
Image is pixelated.

Expected Results:  
Image should be filtered so as to look reasonable at all zoom levels.
