How to Add Font File to Stimulsoft report from embedded font in C# WPF-CodePudding

I use C# WPF and Stimulsoft

I want to send path my font file was embedded to my report when need to show

I have embedded font in my WPF Project and I use it like this :

in XAML :

<Label x:Name="preloader" HorizontalContentAlignment="Center" VerticalContentAlignment="Center" Content="Loading . . ." Margin="319,178,48,34" FontFamily="/WpfApp5;component/FNT/#B Titr" FontSize="48" Background="White"/>

The font was embed from font's folder in my project :

for my report was generated in stimulsoft I cannot embed font but I can send it a path of my font

for that I tried two way

C# Code :

1- :

StiFontCollection.AddFontFile(@"pack://application:,,,/FNT/#B Titr");

this case will show this error :

System.NotSupportedException: 'The given path's format is not supported.'

2- :

var fntpath = Assembly.GetEntryAssembly().GetManifestResourceStream("WpfApp5.FNT.BTITRBD.TTF");
            StiFontCollection.AddFontFile(fntpath.ToString());

and in this fntpath.ToString() is null !

How to do this ?

Please help

CodePudding user response：

The AddFontFile method expects the path of a physical file on disk. You cannot pass in a pack: URI, because it doesn't understand that format. And you cannot just call .ToString() on a Stream, since that won't produce any meaningful information.

You need to extract your font file to a temporary file, and pass the path to that file to the AddFontFile method.

string tempPath = Path.GetTempPath();
string fileName = "WpfApp5.FNT.BTITRBD.TTF";
string fontPath = Path.Combine(tempPath, fileName);
if (!File.Exists(fontPath))
{
    using (var stream = Assembly.GetEntryAssembly().GetManifestResourceStream(fileName))
    using (var output = File.Create(fontPath))
    {
        stream.CopyTo(output);
    }
}

StiFontCollection.AddFontFile(fontPath);
