@kesinwang,

Can you please try using following sample code on your end and share the results.

  public void TestPdfExportIssue() 
       { 
           string path = "C:\\Users\\Muhammad\\Downloads\\temp\\"; 
           string srcFile = path + "demo1000.dwg"; 
           LoadOptions loadOptions = new LoadOptions(); 
           loadOptions.SpecifiedEncoding = CodePages.SimpChinese; 
           // Here you should use loadOptions in Image.Load method 
           CadImage image = (CadImage)Image.Load(srcFile, loadOptions); 
           CadRasterizationOptions rasterizationOptions = new CadRasterizationOptions(); 
           rasterizationOptions.BackgroundColor = Color.White; 
           rasterizationOptions.PageWidth = 1600; 
           rasterizationOptions.PageHeight = 1600; 
           PdfOptions pdfOptions = new PdfOptions(); 
           pdfOptions.VectorRasterizationOptions = rasterizationOptions; 
           image.Save(path + "out_put" + ".pdf", pdfOptions); 
       }

    CadImage image = (CadImage)Image.load(srcFile, loadOptions); 
    CadRasterizationOptions rasterizationOptions = new CadRasterizationOptions(); 
    rasterizationOptions.setBackgroundColor(Color.getWhite());
    rasterizationOptions.setPageWidth(1600);
    rasterizationOptions.setPageHeight(1600);
    PdfOptions pdfOptions = new PdfOptions(); 
    pdfOptions.setVectorRasterizationOptions(rasterizationOptions);
    image.save(path + "out_put" + ".pdf", pdfOptions);

@kesinwang,

I have used the above code sample using latest Aspose.CAD for Java 18.3 on my end and the generated output is fine. Please try using specified version on your end.

@kesinwang,

Have you observed the generated PDF file shared by me in my previous post. I used Aspose.CAD for Java 18.3 in Windows 7 x64 with JDK 1.7_79 on my end. Did you use the updated code sample shared by me as well? Can you please share the details of environment as well on your end along with generated PDF for reference.

@bbd,

您能否尝试使用最新的Aspose.CAD for Java 19.7使用以下示例代码。

public void TestPdfExportIssue()
{
string path = "C:\Users\Muhammad\Downloads\temp\";
string srcFile = path + "demo1000.dwg";
LoadOptions loadOptions = new LoadOptions();
loadOptions.SpecifiedEncoding = CodePages.SimpChinese;
// Here you should use loadOptions in Image.Load method
CadImage image = (CadImage)Image.Load(srcFile, loadOptions);
CadRasterizationOptions rasterizationOptions = new CadRasterizationOptions();
rasterizationOptions.BackgroundColor = Color.White;
rasterizationOptions.PageWidth = 1600;
rasterizationOptions.PageHeight = 1600;
PdfOptions pdfOptions = new PdfOptions();
pdfOptions.VectorRasterizationOptions = rasterizationOptions;
image.Save(path + "out_put" + ".pdf", pdfOptions);
}

你好，已经使用Aspose.CAD for Java 19.7和提供的示例，在linux环境仍旧有中文乱码问题
