            Bug ID: 113918
           Summary: 1bpp non-B&W PNG images are mishandled on Linux in all
                    vcl "backends" ("plugins")
           Product: LibreOffice
           Version: unspecified
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: graphics stack
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: tml at iki.fi

Description:
Open attached document on Windows, it shows up in Writer correctly: An empty
page with an image that has some grey text on white background. That the image
has text is irrelevant, it could be any image, the relevant detail is that the
image (a PNG file) is one bit per pixel, i.e. two colours. but not black and
white, but grey and white.

On Linux, depending on which VCL "backend" (of "plugin" as they also are
called) is used, it either doesn't show at all, the text shows up as black and
the background as white, or even the text as black and the background as grey.
Not even funny.
