Losing pages when convert doc to images

[xiao0207]

I have a 60 pages word document. When i get the total pages of this document, it show me 57 pageCount. When i convert it into image. It come out with 57 images only. What I found out is that some pages contents has been "squeeze" into one page. For example: content in page 4 is just few line text, when convert it into image, the content will "squeeze" to page 3. So how am i suppose to do so that I can get the exactly same amount of pages as the original file when get the page count and images.

This is my code:

//to get total pages
using (Spire.Doc.Document document = new Spire.Doc.Document())
{
document.LoadFromFile(source, Spire.Doc.FileFormat.Auto);
pageNumber = document.PageCount;
}

//convert to images
using (Spire.Doc.Document document = new Spire.Doc.Document())
{
document.LoadFromFileInReadMode(file, Spire.Doc.FileFormat.Docx);
Image[] images = document.SaveToImages(fromPage, toPage, Spire.Doc.Documents.ImageType.Bitmap);

int i = 1;
foreach (Image img in images)
{

var target = path + Path.DirectorySeparatorChar + "Page_" + i.ToString();
var pngTarget = Path.ChangeExtension(target, "png");
img.Save(pngTarget, System.Drawing.Imaging.ImageFormat.Png);
imageList.Add(pngTarget);
i++;
}
}

Hi, I'm too having the same issue where some content of the page is missing or shifted from one page to another page after converting to images and then resulting in total page is lesser than the actual total pages count.

Currently using the latest spire office.net as I am also using together with other spire library

Tested also with the latest spire doc (Version 6.12.1), still having the same issue.

Here attached the part of the docx file and also the output after converted to image for your comparison
