          Priority: medium
            Bug ID: 68360
          Assignee: poppler-bugs at lists.freedesktop.org
           Summary: Fuzzy rendering in SplashOutputDev in latest releases
          Severity: major
    Classification: Unclassified
                OS: All
          Reporter: dr.hyder at gmail.com
          Hardware: x86 (IA32)
            Status: NEW
           Version: unspecified
         Component: splash backend
           Product: poppler

Here's a PDF file that contains scanned (raster) b/w image @ 400dpi, together
with the result of its rendering with pdftoppm from two poppler releases:
0.20.5 & 0.24.0:

The latter (newer version) produces a fuzzy image. In fact, I've also tried
version 0.22.x and it also gives fuzzy results. The effect is not specific to
the PDF file: it is reproduced on any PDF file that contains raster b/w images.

Meanwhile, pdfimages (ImageOutputDev) works just fine. So I figure it must be
the SplashOutputDev
