New Post: Resizing problem in TIFF to PNG conversion

I am trying to convert a .tif to a .png image and resizing it down to 1000 pixels wide. The original image is a scanned text document of 2480x 3507 and I use the resize command on it after reading it in. The resultant image has missing pixels and it seems that anti-aliasing is not working for this.

I tried the sample command as well which works much better than the resize but still some pixels get destroyed. I am using the following code :-

    MagickReadSettings settings = new MagickReadSettings();
    settings.Density = new MagickGeometry(150, 150);

    // Read the PDF into a collection of images
    images.Read(currentDocument.OriginalPath, settings);

    foreach (MagickImage image in images)
    {
       // Formatting image
       image.Format = MagickFormat.Png;
       image.Alpha(AlphaOption.Remove);
       if (image.BaseWidth > image.BaseHeight)
       {
           //image.Resize(1000, 0);
           image.Sample(1000, 0);
       }
       else
       {
           //image.Resize(0, 1000);
           image.Sample(1000, 0);
       }
       image.Quality = 100;
       image.Annotate("Some Watermark", Gravity.Southwest);

       // Write the image to the specified path as a PNG
       image.Write("test.png");
    }

Am I missing something in this?
I am using the latest 6.8.9.401 Q16 x64 version of the Magick.NET.

Thanks
