1.How to convert the CAD image into HD (vectorgraph)? CAD conversion of the picture is very vague.
2.If CAD is 3D, the code does not set this property (setTypeOfEntities (TypeOfEntities.Entities3D)) export PDF is blank, and so is 2D CAD。How to know whether CAD is 3D or 2D？
3.Maximum file size can be converted？
4.Null pointer to transform PDF，see 2.jpg ,2.dwg
code:
public static void main(String[] args)
{
String dataDir = START + "DWGDrawings\\";
String srcFile = dataDir + "2.dwg";
long now = new Date().getTime();
// Load a CAD drawing in an instance of CadImage
CadImage image = (CadImage) Image.load(srcFile);
// Create an instance of CadRasterizationOptions
CadRasterizationOptions rasterizationOptions = null;
PdfOptions pdfoptions = null;
JpegOptions bmp = null;
int i = 1;
rasterizationOptions = new CadRasterizationOptions();
rasterizationOptions.setCenterDrawing(true);
rasterizationOptions.setAutomaticLayoutsScaling(true);
rasterizationOptions.setTypeOfEntities(TypeOfEntities.Entities2D);
// rasterizationOptions.setLayouts(new String[] {string2});
//rasterizationOptions.setTypeOfEntities(TypeOfEntities.Entities3D);
pdfoptions = new PdfOptions();
// Set VectorRasterizationOptions property to the instance of CadRasterizationOptions
pdfoptions.setVectorRasterizationOptions(rasterizationOptions);
// Export each layer to JPEG format
image.save(END + i + "1222331.pdf", pdfoptions);
System.out.println(i);
System.out.println(new Date().getTime() - now);
}
5.CAD conversion PDF and picture conversion content is not the same, PDF lost part of the map and text see 2.dwg（convert 2.dwg to jpg and pdf）
6.When we want to convert the about 70M (file size) CAD to throw the exception . see 1.jpg （The file is too large to upload）
