Document.PageCount returns Incorrect Value | Extract Pages from DOCX using .NET

vs6060_qq_com · June 25, 2023, 6:52pm

i have a docx file (please see the attachment), i use the below code to get pagecount:

var doc = new Aspose.Words.Document(fileFullName);

int pageCount = doc.PageCount;

for (int page = 0; page < pageCount; page++)
{
    // Save each page as a separate document.
    var extractedPage = doc.ExtractPages(page, 1);
    var toFileName = Path.Combine(@"O:\", $"SplitDocument.PageByPage_{ page + 1}.docx");
    extractedPage.Save(toFileName);
}

the pagecount property returns 2 which is incorrect, and i separated the document to 2 docs file please also see the attments.

i dont know what’s wrong with my codes, can you please help me to find out why the pagecount property is not incorrect.

thank you very much.

Please note that Aspose.Words requires TrueType fonts when rendering document to fixed-page formats (JPEG, PNG, PDF or XPS) and calling Document.PageCount or Document.ExtractPages method. You need to install fonts that are used in your document on the machine where you are extracting pages of document. Please refer to the following articles:

hi manzoor:
thank you for the reply, to follow your suggestion,i did the below steps
0) prepare my test document.common_FOOTER-Final.docx (20.3 KB)

got the all font names provided by FontSettings.DefaultInstance by the below codes:

    var fontSettings = FontSettings.DefaultInstance;
     var defaultFontNames = new List<string>();
     fontSettings.GetFontsSources().ToList().ForEach(t =>
     {
         var thisFontNames = t.GetAvailableFonts().Select(t => t.FullFontName).ToList();
         defaultFontNames.AddRange(thisFontNames);
     });

i got a name list ,please see the attachment(defaultnames.docx) (19.6 KB)

got the document missing fonts:

     var fileFullName = @"common_FOOTER-Final.docx";
     var doc = new Document(fileFullName);
     var documentFontNames = doc.FontInfos.Select(t => new
     {
         Name = t.Name,
         AltName = t.AltName
     }).ToList();

     var fontSettings = FontSettings.DefaultInstance;

     var defaultFontNames = new List<string>();
     fontSettings.GetFontsSources().ToList().ForEach(t =>
     {
         var thisFontNames = t.GetAvailableFonts().Select(t => t.FullFontName).ToList();
         defaultFontNames.AddRange(thisFontNames);
     });
     var notFoundNames = documentFontNames.Where(t => !defaultFontNames.Contains(t.Name)).ToList();
     notFoundNames = notFoundNames.Where(t => !string.IsNullOrEmpty(t.AltName) && !defaultFontNames.Contains(t.AltName)).ToList();

the values of “notFoundNames” was:
Name = “等线”, AltName = "DengXian"
"隶书", AltName = "微软雅黑"

i checked the default font name list , found the similar fonts,:

DengXian Regular
DengXian Bold
DengXian Light
Microsoft YaHei

i though ,the next should be using " Substitute features", by the bloew

     var fileFullName = @"common_FOOTER-Final.docx";
     var fontSettings = FontSettings.DefaultInstance;
     fontSettings.SubstitutionSettings.FontConfigSubstitution.Enabled = true;
     var xml = @"
         <TableSubstitutionSettings xmlns=""Aspose.Words""> 
             <SubstitutesTable> 
                 <Item OriginalFont=""等线"" SubstituteFonts=""DengXian Regular"" /> 
                 <Item OriginalFont=""隶书"" SubstituteFonts=""Microsoft YaHei"" /> 
                 <Item OriginalFont=""微软雅黑"" SubstituteFonts=""Microsoft YaHei"" /> 
             </SubstitutesTable> 
         </TableSubstitutionSettings>";
     var bytes = Encoding.UTF8.GetBytes(xml);
     using var stream = new MemoryStream(bytes);
     fontSettings.SubstitutionSettings.TableSubstitution.Load(stream);
     var loadOptions = new LoadOptions();
     loadOptions.FontSettings = fontSettings;
     var doc = new Aspose.Words.Document(fileFullName, loadOptions);
     doc.UpdatePageLayout();
     doc.UpdateTableLayout();
     int pageCount = doc.PageCount;
     for (int page = 0; page < pageCount; page++)
     {
         // Save each page as a separate document.
         var extractedPage = doc.ExtractPages(page, 1);
         var toFileName = Path.Combine(@"O:\", $"SplitDocument.PageByPage_{ page + 1}.docx");
         extractedPage.Save(toFileName);
     }

but i still got 2 pages.

could you please help me point out where the prombles are.

thank you very much.

tahir.manzoor · August 6, 2021, 3:19pm

@vs6060_qq_com

While using the latest version of Aspose.Words for .NET 21.8, we have not found the shared issue. Please make sure that the fonts used in your document are installed on the machine where you are executing the application.

vs6060_qq_com · August 7, 2021, 5:26am

@Tahir,

i am trying to remove not found fonts from the document:
[0]: “等线,DengXian”
[1]: “隶书,微软雅黑”

please are there any aspose.words API(s) to remove these fonts?

tahir.manzoor · August 7, 2021, 8:26am

@vs6060_qq_com

Your document has not embedded fonts. Could you please share why you want to remove fonts from document?

If you want to change the font name, you can use Run.Font.Name property to change the font of Run nodes. For paragraphs, please use ParagraphFormat.Style property.

vs6060_qq_com · June 25, 2023, 6:53pm

hi Tahir,
according your below help:
" we have not found the shared issue. Please make sure that the fonts used in your document are installed on the machine where you are executing the application.".

it sems there is only one reason which fired the wrong page count : missing fonts

so i though ,after removing these missing fonts, i should get the correct page count.

that’s the reason i want to remove the below 2 fonts from my document:

i also did the below 2 deep investigations:

by the FontSettings.DefaultInstance api ,i can get a full aspose.word loaded fonts,on the list,i can’t find “等线” ,but i can find it on my computer:Capture.PNG (37.1 KB)
probably FontSettings.DefaultInstance api does not work very well?
and i also used the below code to force correct fonts:
var fileFullName = @“common_FOOTER-Final.docx”;
var fontSettings = FontSettings.DefaultInstance;
fontSettings.SubstitutionSettings.FontConfigSubstitution.Enabled = true;
var xml = @"
<TableSubstitutionSettings xmlns="“Aspose.Words”">

<Item OriginalFont="“等线”" SubstituteFonts="“DengXian Regular”" />
<Item OriginalFont="“隶书”" SubstituteFonts="“Microsoft YaHei”" />
<Item OriginalFont="“微软雅黑”" SubstituteFonts="“Microsoft YaHei”" />

";
var bytes = Encoding.UTF8.GetBytes(xml);
using var stream = new MemoryStream(bytes);
fontSettings.SubstitutionSettings.TableSubstitution.Load(stream);
var loadOptions = new LoadOptions();
loadOptions.FontSettings = fontSettings;
var doc = new Aspose.Words.Document(fileFullName, loadOptions);
doc.UpdatePageLayout();
doc.UpdateTableLayout();
int pageCount = doc.PageCount;

but i still can’t get correct page count.
