    Description

      As you can easily see (or try out):

      the Qt Flags are "positive" the pdfium flags are "negativ".
      Therefore a negation is missing in the code

       

      if (renderFlags & QPdf::RenderTextAliased)
      flags |= FPDF_RENDER_NO_SMOOTHTEXT;
      if (renderFlags & QPdf::RenderImageAliased)
      flags |= FPDF_RENDER_NO_SMOOTHIMAGE;
      if (renderFlags & QPdf::RenderPathAliased)

      flags |= FPDF_RENDER_NO_SMOOTHPATH;

       

      Turning AntiAliasing on in Qt's RenderFlags actually turns them off in pdfium.
