Paraghraph font size

[geraluca]

If in the paragraph I select the font and insert the size, in some cases the document selects a different size, why?

[PrzemyslawKlys]

You need to give me context and an example to replicate this issue. Otherwise I won't be able to help.

[geraluca]

docux.Sections(0).Margins.Bottom = 10 docux.Sections(0).Margins.Top = 10 docux.Sections(0).Margins.Left = 600 docux.Sections(0).Margins.Right = 600

this is my code, if top and bottom change the value, the top and bottom margins don't change, instead left and right work and change

[geraluca]

docux.Settings.FontFamily = "Arial" docux.Settings.FontSize = 9

if I place a font in the document and then in a cell or in a paragraph I want to use a different fontsize I won't allow it

[PrzemyslawKlys]

Simple example that tries to replicate your issue:

public static void Example_BasicWordWithMargins(string folderPath, bool openWord) {
    Console.WriteLine("[*] Creating standard document with margins");
    string filePath = System.IO.Path.Combine(folderPath, "EmptyDocumentWithMargins.docx");
    using (WordDocument document = WordDocument.Create(filePath)) {
        document.Sections[0].Margins.Bottom = 10;
        document.Sections[0].Margins.Left = 600;
        document.Sections[0].Margins.Top = 10;
        document.Sections[0].Margins.Right = 600;
        document.Save(openWord);
    }
}

Result

Works fine to me.

Another example of yours:

public static void Example_BasicWordWithMargins(string folderPath, bool openWord) {
    Console.WriteLine("[*] Creating standard document with margins");
    string filePath = System.IO.Path.Combine(folderPath, "EmptyDocumentWithMargins.docx");
    using (WordDocument document = WordDocument.Create(filePath)) {
        document.Sections[0].Margins.Bottom = 10;
        document.Sections[0].Margins.Left = 600;
        document.Sections[0].Margins.Top = 10;
        document.Sections[0].Margins.Right = 600;

        document.Settings.FontFamily = "Arial";
        document.Settings.FontSize = 9;

        document.AddParagraph("This should be Arial 9");

        var par = document.AddParagraph("This should be Tahoma 20");
        par.FontFamily = "Tahoma";
        par.FontSize = 20;

        document.Save(openWord);
    }
}

I am not sure what library you are using and how, but the examples you provided work fine in C# and should work fine in other .NET languages.

i use visual studio, when i load the code docux.AddHeadersAndFooters() then obviously I get an image in the header and a text in the footers, this doesn't allow me to reduce the spaces as I would like

[PrzemyslawKlys]

Either you will provide an example code that I can run that shows your problem or I won't help you. docux.AddHeadersAndFooters() doesn't add images, nor spaces, so unless you will put an effort in creating proper issue I'm going to close the issue with comment "works as expected".

  newfile = "myfile.doc"

    Using docux As WordDocument = Create(Application.StartupPath() & newfile)

        docux.Sections(0).Margins.Bottom = 10

        docux.Sections(0).Margins.Left = 600
        docux.Sections(0).Margins.Right = 600

        docux.AddHeadersAndFooters()

    End Using

Here's your code in c#

public static void Example_BasicWordWithMarginsAndImage(string folderPath, bool openWord) {
    Console.WriteLine("[*] Creating standard document with margins");
    string filePath = System.IO.Path.Combine(folderPath, "DocumentWithMarginsAndImage.docx");
    using (WordDocument document = WordDocument.Create(filePath)) {

        string imagePaths = System.IO.Path.Combine(System.IO.Directory.GetCurrentDirectory(), "Images");
        var filePathImage = System.IO.Path.Combine(imagePaths, "EvotecLogo.png");

        document.Sections[0].Margins.Bottom = 10;
        document.Sections[0].Margins.Top = 10;
        document.Sections[0].Margins.Left = 600;
        document.Sections[0].Margins.Right = 600;

        document.Settings.FontFamily = "Arial";
        document.Settings.FontSize = 9;

        document.AddHeadersAndFooters();

        document.Header.Default.AddParagraph().AddImage(filePathImage, 734, 92);
        document.Header.Default.Paragraphs[0].SetFontFamily("Arial");
        document.Header.Default.Paragraphs[0].SetFontSize(7).Bold = false;

        document.Footer.Default.AddParagraph();
        document.Footer.Default.Paragraphs[0].SetFontFamily("Arial");
        document.Footer.Default.Paragraphs[0].SetFontSize(7).Bold = false;
        document.Footer.Default.Paragraphs[0].ParagraphAlignment = JustificationValues.Right;
        document.Footer.Default.Paragraphs[0].Text = "SMA.5.doc 04/10/19";
        document.Footer.Default.Paragraphs[0].LineSpacingAfter = 0;
        document.Footer.Default.Paragraphs[0].LineSpacingBefore = 0;
        document.Footer.Default.AddPageNumber(WordPageNumberStyle.PageNumberXofY);

        document.Footer.Default.AddParagraph();
        document.Footer.Default.Paragraphs[0].SetFontFamily("Arial");
        document.Footer.Default.Paragraphs[0].SetFontSize(7).Bold = false;
        document.Footer.Default.Paragraphs[0].ParagraphAlignment = JustificationValues.Center;
        document.Footer.Default.Paragraphs[0].Text = "My address";
        document.Footer.Default.Paragraphs[0].LineSpacingAfter = 0;
        document.Footer.Default.Paragraphs[0].LineSpacingBefore = 0;

        var par00 = document.AddParagraph("My text");
        par00.ParagraphAlignment = JustificationValues.Left;
        par00.SetFontFamily("Arial").SetFontSize(10).Bold = true;
        par00.LineSpacingAfter = 50;
        par00.LineSpacingBefore = 0;

        var par01 = document.AddParagraph("My declaration");
        par01.ParagraphAlignment = JustificationValues.Left;
        par01.SetFontFamily("Arial").SetFontSize(10).Bold = true;
        par01.LineSpacingAfter = 50;
        par01.LineSpacingBefore = 200;

        document.Save(openWord);
    }
}

Here's the output of it:

But since you have provided no information what do you actually want to achieve it's really hard to help you.

One thing to notice in your code is that you add multiple paragraphs to Footer, but overwrite SMA.5.doc, with My Address.

Hope this helps. if you want to have it in the same line you would either use tabs or invisible table to position it properly.

Double footers is an error, optionally the first paragraph or the second. What I would like to achieve is to gain space for the texts, I would like to decrease the empty space above the logo image and below the footers, it would help to recover some more lines in the document. Instead going back to the font size, yes, as you demonstrated in the example it works, but strangely in some paragraphs or in some tables it doesn't work even though the code is identical, this is inexplicable but it happens. Another question, how is it possible to save in pdf? Thanks for your time.
