Convert text to mesh

Following code presents example of converting text to mesh

• C++

  #include <MRMesh/MRMesh.h>
  #include <MRMesh/MRMeshSave.h>
  #include <MRSymbolMesh/MRSymbolMesh.h>
   
  #include <iostream>
   
  int main( int argc, char* argv[] )
  {
      if ( argc < 3 )
      {
          std::cerr << "Usage: MeshFromText fontpath text" << std::endl;
          return EXIT_FAILURE;
      }
      const auto* fontPath = argv[1];
      const auto* text = argv[2];
   
      // set text-to-mesh parameters
      MR::SymbolMeshParams params {
          // input text
          .text = text,
          // font file name
          .pathToFontFile = fontPath,
      };
      auto convRes = MR::createSymbolsMesh( params );
      if ( !convRes )
      {
          std::cerr << "Failed to convert text to mesh: " << convRes.error() << std::endl;
          return EXIT_FAILURE;
      }
   
      auto saveRes = MR::MeshSave::toAnySupportedFormat( *convRes, "mesh.ply" );
      if ( !saveRes )
      {
          std::cerr << "Failed to save result: " << saveRes.error() << std::endl;
          return EXIT_FAILURE;
      }
   
      return EXIT_SUCCESS;
  }
