Embedded TrueType font for PDF export in Core Web

[Tomasz]

Hi

I have this field with Arial font (i need to emulate checkbox):

=IIF(Fields!OnTerminal.Value="True",chr(9745),chr(9634))

And this is my code on server side:

public void OnReportLoaded(ReportViewerOptions reportOption)
{
    reportOption.ReportModel.PDFOptions ??= new PDFOptions();

    AddFonts(reportOption.ReportModel.PDFOptions);
}

private void AddFonts(PDFOptions pdfOpt) 
{ 
    AddFont(pdfOpt, "Wingdings"); 
    AddFont(pdfOpt, "Arial"); 
} 

public void AddFont(PDFOptions pdfOpt, string name) 
{ 
    var basePath = _hostingEnvironment.WebRootPath;

    var path = Environment.OSVersion.Platform == PlatformID.Unix ||
               Environment.OSVersion.Platform == PlatformID.MacOSX
        ? @"/" + basePath + @"/fonts/"
        : basePath + @"\fonts\";

    var file = path + name + @".ttf";
    
    var inputStream = new FileStream(file, FileMode.Open, FileAccess.Read); 
    
    pdfOpt.Fonts ??= new Dictionary<string, Stream>(StringComparer.OrdinalIgnoreCase); 
    
    pdfOpt.Fonts.Add(name, inputStream); 
} 

based on documentation, 

https://www.syncfusion.com/kb/10753/how-to-pass-embedded-font-for-exporting-in-onreportloaded-method

but it doesn't work - in Report Viewer its is ok.

But when i export to PDF, there are empty fields, without nothing.

Can you help me?

Hi Tomasz,  

We are still checking on this causes in the asp.net core. We will update the status by 1st Dec 2020 with priority. However the winding font support we have limited support so is this possible to use the check box image instead of winding font ?

Yes, i don't need wingdings font. I used it for emulate checkbox only.

Hi Tomasz, 

 

If you do not want to add a checkbox using font then you can do it by using an image. Please refer the below documentation for add checkbox using image.
https://help.boldreports.com/standalone-report-designer/how-to/add-check-box-in-table-report-using-image-item/#how-to-add-checkbox-in-table-using-image
