Attached is a demo written in C# in .NET4 VS 2017 that shows how to use the ImageViewer Control as well as the Annotations SDK to navigate through a multipage input document, add redaction objects to the document, and then flatten and save out the document as 300x300 8.5inx11in regardless of what the input size was.

To run this project, make sure the output path is set to

Here is the relevant code for each part:

Adding a container for each page contained in the image viewer:
Code:
 //Add an Annotation Container for each page to the Container Collection
               pageContainers.Clear();
               for (int page = 1; page <= imageViewer.Image.PageCount; page++)
               {
                  AnnContainer pageContainer = new AnnContainer();
                  pageContainer.Mapper.MapResolutions(imageViewer.Image.XResolution,
                     imageViewer.Image.YResolution,
                     imageViewer.Image.XResolution,
                     imageViewer.Image.YResolution);
                  pageContainer.Size = pageContainer.Mapper.SizeToContainerCoordinates(imageViewer.ImageSize.ToLeadSizeD());
                  pageContainers.Add(pageContainer);
               }
               //Attach the first container to the annAutomation
               annAutomation.AttachContainer(pageContainers.FirstOrDefault(c => pageContainers.IndexOf(c) + 1 == imageViewer.Image.Page), null);


Resize and burn
Code:
//Burn each container to each page and then resize it to 300x300 DPI 8.5inx11in
               RasterImage flatImage = null;
               for (int page = 0; page < imageViewer.Image.PageCount; page++)
               {
                  imageViewer.Image.Page = page + 1;
                  AnnWinFormsRenderingEngine renderer = annManager.RenderingEngine as AnnWinFormsRenderingEngine;
                  RasterImage flatPage = renderer.RenderOnImage(pageContainers[page], imageViewer.Image.Clone());

                  flatPage.XResolution = 300;
                  flatPage.YResolution = 300;

                  SizeCommand size = new SizeCommand()
                  {
                     Flags = RasterSizeFlags.Bicubic,
                     Height = 3300,
                     Width = 2550
                  };
                  size.Run(flatPage);


                  if (flatImage == null)
                     flatImage = flatPage;
                  else
                     flatImage.AddPage(flatPage);
               }
               //Save the final FlatImage to disk
               using (RasterCodecs codecs = new RasterCodecs())
                  codecs.Save(flatImage, dlg.FileName, RasterImageFormat.RasPdfG4, 1);

               //Reset the page back to the first page
               imageViewer.Image.Page = 1;
