Background color for PdfCompositeField

[Thu Nguyen]

Hi,

I am creating a PdfCompositeField object that will draw a PdfPageNumberField and PdfPageCountField one in footer of pdf page.

I would like to set background color for this content.

For example:

Page 1 of 10

How can I do this?

Thanks,

Hi Thu, 

We do not have default option to achieve your requirement, but it is possible to achieve using the below workaround. 

void CreatePDF() 

{ 

    PdfDocument document = new PdfDocument(); 

    document.Pages.Add(); 

    document.Pages.Add(); 

 

    AddFooter(document); 

    document.Save("Sample.pdf"); 

    document.Close(true); 

} 

 

 

void AddFooter(PdfDocument doc) 

{ 

    RectangleF rect = new RectangleF(0, 0, doc.Pages[0].GetClientSize().Width, 50); 

    PdfPageTemplateElement footer = new PdfPageTemplateElement(rect); 

    PdfFont font = new PdfStandardFont(PdfFontFamily.Helvetica, 8); 

    PdfSolidBrush brush = new PdfSolidBrush(Color.Gray); 

 

    PdfPageNumberField pageNumber = new PdfPageNumberField(font, brush); 

 

    PdfPageCountField count = new PdfPageCountField(font, brush); 

 

    string pageNumberFormat = "Page {0} of {1}"; 

    PointF pageNumberLocation = new PointF(100, 20); 

    SizeF dimensionOfPageNumber = font.MeasureString(pageNumberFormat); 

 

    footer.Graphics.DrawRectangle(PdfBrushes.Aquamarine,  

        new RectangleF(new PointF(pageNumberLocation.X - 5F, pageNumberLocation.Y), dimensionOfPageNumber)); 

 

    PdfCompositeField compositeField = new PdfCompositeField(font, PdfBrushes.Black, pageNumberFormat, pageNumber, count); 

    compositeField.Draw(footer.Graphics, pageNumberLocation); 

 

    doc.Template.Bottom = footer; 

}

Thanks for your replying,

I tried with this solution. But it only measures on "Page {0} of {1}". With a longer string, it cannot fill all.

 Hi Thu, 

Thanks for your update. I modified the sample to exactly meet your requirement. This sample will manually load the PDF document and add the footer instead of using the Composite field. Please refer the below code snippet and the sample. 

Sample Link: http://www.syncfusion.com/downloads/support/forum/142367/ze/ConsoleApp1-1653136235  

// Creating source document to add footer 

PdfDocument doc = new PdfDocument(); 

 

for (int pageIndex = 0; pageIndex < 100; pageIndex++) 

{ 

    doc.Pages.Add(); 

} 

MemoryStream ms = new MemoryStream(); 

doc.Save(ms); 

ms.Position = 0; 

 

// Add footer 

PdfLoadedDocument ldDoc = new PdfLoadedDocument(ms); 

for (int pageIndex = 0; pageIndex < ldDoc.PageCount; pageIndex++) 

{ 

    // Footer location in the page 

    PointF footerLocation = new PointF(200, 600); 

    PdfFont footerFont = new PdfStandardFont(PdfFontFamily.TimesRoman, 35); 

    string pageNumberText = "Page " + pageIndex.ToString() + " of " + ldDoc.PageCount.ToString(); 

    SizeF footerDimension = footerFont.MeasureString(pageNumberText); 

 

    // Footer content goes here 

    ldDoc.Pages[pageIndex].Graphics 

        .DrawRectangle(PdfBrushes.Gray, new Syncfusion.Drawing.RectangleF(footerLocation, footerDimension)); 

    ldDoc.Pages[pageIndex].Graphics 

        .DrawString(pageNumberText, footerFont, PdfBrushes.Black, footerLocation); 

} 

 

using (var docStream = File.Create("Output.pdf")) 

    ldDoc.Save(docStream);

Thanks,

I hope "background for dynamic field" will be a feature in future. :)

You know we should take care:

- length of text

- word-wrap

Hi Thu Nguyen, 

Yes will consider this as a feature request. But we do not have any immediate plans to implement this feature. Please follow the feature status in the below link.
