在将EMF文件转换为PDF时出现乱码的问题，可能是由于EMF文件中的某些元素未能正确解析或渲染。您可以尝试以下步骤来解决此问题：

  1. 检查EMF文件：确保EMF文件本身没有损坏，并且可以在其他图形查看器中正常显示。

  2. 调整分辨率：在设置EmfRasterizationOptions时，确保分辨率设置合理。您可以尝试不同的分辨率值，以改善输出质量。

  3. 使用不同的PDF选项：尝试使用不同的PdfOptions设置，特别是与图形渲染相关的选项。

  4. 更新Aspose库：确保您使用的是最新版本的Aspose.Imaging库，因为更新可能包含修复和改进。

  5. 示例代码：以下是您可以尝试的代码示例，确保在设置页面宽度和高度时使用适当的值：

using (var image = (EmfImage)Aspose.Imaging.Image.Load(childEmfFilePath))
{
    using (FileStream outputStream = new FileStream(childPdfFilePath, FileMode.Create))
    {
        using (PdfOptions pdfOptions = new PdfOptions())
        {
            using (EmfRasterizationOptions emfRasterization = new EmfRasterizationOptions())
            {
                float resolution = 96.0f; // 尝试不同的分辨率
                emfRasterization.PageWidth = image.WidthF * resolution / 100; // 根据需要调整
                emfRasterization.PageHeight = image.HeightF * resolution / 100; // 根据需要调整
                pdfOptions.VectorRasterizationOptions = emfRasterization;
                pdfOptions.ResolutionSettings = new Aspose.Imaging.ResolutionSetting
                {
                    HorizontalResolution = resolution,
                    VerticalResolution = resolution
                };
            }
            try
            {
                image.Save(outputStream, pdfOptions);
            }
            catch (Exception ex)
            {
                // 处理异常
                Console.WriteLine($"转换过程中发生错误: {ex.Message}");
            }
        }
    }
}

如果问题仍然存在，您可能需要考虑将EMF文件转换为其他格式（如PNG或JPEG），然后再将其转换为PDF，以避免直接从EMF转换时可能出现的兼容性问题。

新给的代码，转PDF还是存在乱码情况

转的PDF好像也不是乱码，好像是转的字有部分缺失
