嵌入字体的 PDFsharp / MigraDoc 字体解析器：System.ArgumentException：找不到字体 'Ubuntu'
PDFsharp / MigraDoc font resolver for embedded fonts: System.ArgumentException: Font 'Ubuntu' cannot be found
我正在使用 MigraDoc 在部署到 Azure 云的 ASP.NET5 MVC6 Web 应用程序中生成 PDF。我使用的是 1.50 beta-2 版，但我也尝试过使用 v1.50 beta-1 和 v1.32。
当应用程序在本地 运行ning 时，我已成功生成 PDF。但是，由于无法访问任何字体，当应用程序在云服务器上 运行ning 时，我在生成 PDF 时遇到了很大的麻烦。 Following the PDFsharp docs，我尝试通过在代码中嵌入字体来创建 "private font"。
我直接使用 PDFsharp 在云端生成 PDF 成功了
public static MyResolver FontResolver = new MyResolver();
public void RenderPdf(CreateDocumentViewModel viewModel)
{
GlobalFontSettings.FontResolver = FontResolver;
//...
XFont font = new XFont("times-roman", 12, XFontStyle.Regular);
//This font is then used in DrawString.
}
不过，我现在想利用 MigraDoc，这样我就不必自己进行所有排版工作了。
我遵循了 Thomas Hövel 博客 here (this is the new one for beta-2, although I had also previously followed his earlier post for beta-1 上的出色指南。他的项目按原样在本地对我来说非常适合。
