The problem of converting dwg files to JPEG。

1

What is the reason why some dwg files cannot be opened with CAD after being converted to dxf format?

2

When converting a dwg file to jpeg, the conversion is slow. Is there any way to convert it faster

@ShaoNanFeng,
please attach the initial DWG file and conversion code, so we can debug and see what makes the export slow.

public static void main(String[] args) throws Exception {
        File file = new File("D:\\test.dwg");
        InputStream inputStream = new FileInputStream(file);
        CADFileToImage(inputStream, "D:\\test.jpg");
    }
public static void CADFileToImage(InputStream inputStream, String dataDir) throws IOException {

        CadImage image = (CadImage) Image.load(inputStream);

        // 设置输出格式为 JPEG
        JpegOptions jpegOptions = new JpegOptions();
        CadRasterizationOptions cadRasterizationOptions = new CadRasterizationOptions();
        cadRasterizationOptions.setPageWidth(4200);
        cadRasterizationOptions.setPageHeight(2970);
        jpegOptions.setVectorRasterizationOptions(cadRasterizationOptions);
        image.save(dataDir, jpegOptions);
    }

It takes 16 seconds for this code to convert a dwg file to a jpeg file. Please check if it works properly

@ShaoNanFeng,
I can confirm this issue, we will try to improve this performance in the scope of CADJAVA-11394.
