Aspose.CAD for Java 1.0.0 Release Notes
We are pleased to announce the first release of Aspose.CAD for Java. It allows you to convert AutoCAD DWG and DXF files to PDF and Raster images. It is a native API and does not require AutoCAD or any other software to be installed.
You can also convert the selected layers and layouts from the AutoCAD files. The conversion to PDF and Raster images is of very high quality. At the moment we support the following Cad image types for loading (please refer to the https://autodesk.blogs.com/between_the_lines/autocad-release-history.html DWG file history): o CadR11 o CadR13 o CadR14 o CadR2000 o CadR2004 o CadR2010 o CadR2013

Public API and Backward Incompatible Changes
Please note that Aspose.CAD API was split from Aspose.Imaging API, hence its public API is almost the same so you can easily migrate to Aspose.CAD by renaming the packages to com.aspose.cad instead of com.aspose.imaging. Following is an example to convert CAD documents to PDF using Aspose.Imaging and Aspose.CAD respectively. You can notice that just com.aspose.imaging package has been replaced with com.aspose.cad.
Aspose.Imaging Code
String sourceFilePath = myDir + "sample.dxf";
//Load a CAD drawing
com.aspose.imaging.Image image = com.aspose.imaging.Image.load(sourceFilePath);
//Create an instance of CadRasterizationOptions and set its various properties
com.aspose.imaging.imageoptions.CadRasterizationOptions rasterizationOptions = new com.aspose.imaging.imageoptions.CadRasterizationOptions();
rasterizationOptions.setPageWidth(1600);
rasterizationOptions.setPageHeight(1600);
//Create an instance of PdfOptions
com.aspose.imaging.imageoptions.PdfOptions pdfOptions = new com.aspose.imaging.imageoptions.PdfOptions();
//Set the VectorRasterizationOptions property
pdfOptions.setVectorRasterizationOptions(rasterizationOptions);
//Export the DXF to PDF
image.save(myDir + "result.pdf", pdfOptions);Aspose.CAD Code
// The path to the resource directory.
String dataDir = Utils.getDataDir(ExportDXFDrawingToPDF.class) + "DXFDrawings/";
String srcFile = dataDir + "conic_pyramid.dxf";
com.aspose.cad.Image image = com.aspose.cad.Image.load(srcFile);
// Create an instance of CadRasterizationOptions and set its various properties
com.aspose.cad.imageoptions.CadRasterizationOptions rasterizationOptions = new com.aspose.cad.imageoptions.CadRasterizationOptions();
rasterizationOptions.setBackgroundColor(Color.getWhite());
rasterizationOptions.setPageWidth(1600);
rasterizationOptions.setPageHeight(1600);
// Create an instance of PdfOptions
com.aspose.cad.imageoptions.PdfOptions pdfOptions = new com.aspose.cad.imageoptions.PdfOptions();
// Set the VectorRasterizationOptions property
pdfOptions.setVectorRasterizationOptions(rasterizationOptions);
// Export the DXF to PDF
image.save(dataDir + "conic_pyramid_out_.pdf", pdfOptions);
