PDFSimpleExport - Font Selection Ignored in PDF Export

[Raffaele-Doti]

As suggested in Issue #623 I tried to install fonts in my Docker Image throught Dockerfile. Anyway fonts still continue to be ignored from PDFSimpleExport in FastReport.

P.S. Suggested command sudo apt-get install ttf-mscorefonts-installer doesn't work after some Googling I ended up with this :

RUN sed -i'.bak' 's/$/ contrib/' /etc/apt/sources.list
RUN apt-get update; apt-get install -y ttf-mscorefonts-installer fontconfig

Steps to Reproduce:

Open the FastReport Community Edition desktop designer. Create a new report or open an existing one. Add a text box to the report. Change the font of the text box to a different font (e.g., Comic Sans MS). Save the .frx template to a project folder. Install fonts throught Dockerfile Import the template by code using the Report class. Export the report to PDF using the PDFSimpleExport class. Observe that the exported PDF does not have the font applied as expected. Environment:

FastReport.Export.PdfSimple.PDFSimpleExport version: 2023.2.23 Operating System: Docker Linux Container Expected Behavior: The PDF export should use the font selected in the designer for the text boxes.

Actual Behavior: The PDF export is using a default font, ignoring the font selected in the designer.

Code Snippet:

// This is a simplified version of the method from my codebase.
try
{
  // Create a new report and load the FRX template
  Report report = Report.FromFile(@"path/to/file");
  // Update existing connection from the report with our json data source.
  var jsonConnection = report.Dictionary.FindByName("existingConnectionName") as FastReport.Data.DataConnectionBase;
  var builder = new FastReport.Data.JsonConnection.JsonDataSourceConnectionStringBuilder(jsonConnection.ConnectionString)
  {
      Json = jsonDataSource
  };
  jsonConnection.ConnectionString = builder.ConnectionString;
  // Prepare the report by compiling the data
  report.Prepare();
  // Export the report to the specified output file path with the provided filename (e.g., PDF)
  report.Export(simplyPdfExporter, exportFilePath);
  // Dispose of the report after use
  report.Dispose();
  // Report generation successful
  return true; 
}
catch (Exception e)
{
   // Handle any exceptions that might occur during report generation
   logger.LogError(e.Message);
   // Report generation failed
   return false; 
}

I tried to integrate your Dockerfile in my solution and it worked ( remind to use System.Configuration.ConfigurationManager version <= 6.0.1 in order to avoid System.Drawing.Common exception ). You only missed to run the command to install the libgdiplus library so before the font command installation it's mandatory to run this command in the Dockerfile : RUN apt-get update && apt-get install -y libgdiplus Thank you, appreciate it.
