Aspose公司今天发布了Aspose.CAD for Java 1.0版本，该产品是一个新的专门用于处理CAD文件的Java控件，可以处理包含DWG和DXF格式的CAD文件，在发布改产品的后三个月内Aspose.Imaging产品将逐步删除其中的CAD处理功能，到时候客户如果需要CAD文件处理的功能就只有选择Aspose.CAD for Java了，在这次发布的该产品主要的功能如下：

1.转换CAD文件格式为PDF文件格式

String dataDir = Utils.getDataDir(ConvertDWGFileToPDF.class) + "DWGDrawings/";

String srcFile = dataDir + "Bottom_plate.dwg";

 

Image image = Image.load(srcFile);

 

// Create an instance of CadRasterizationOptions and set its various properties

CadRasterizationOptions rasterizationOptions = new CadRasterizationOptions();

rasterizationOptions.setBackgroundColor(Color.getWhite());

rasterizationOptions.setPageWidth(1600);

rasterizationOptions.setPageHeight(1600);

 

// Create an instance of PdfOptions

PdfOptions pdfOptions = new PdfOptions();

// Set the VectorRasterizationOptions property

pdfOptions.setVectorRasterizationOptions(rasterizationOptions);

 

// Export the DWG to PDF

image.save(dataDir + "Bottom_plate_out_.pdf", pdfOptions);

2.转换CAD格式文件为光栅图片格式

String dataDir = Utils.getDataDir(ConvertCADDrawingToRasterImageFormat.class) + "CADConversion/";

String srcFile = dataDir + "conic_pyramid.dxf";

 

Image image = Image.load(srcFile); 

 

// Create an instance of CadRasterizationOptions

CadRasterizationOptions rasterizationOptions = new CadRasterizationOptions();

// Set page width & height

rasterizationOptions.setPageWidth(1200);

rasterizationOptions.setPageHeight(1200);

 

// Create an instance of PngOptions for the resultant image

ImageOptionsBase options = new PngOptions();

//Set rasterization options

options.setVectorRasterizationOptions(rasterizationOptions);

 

// Save resultant image

image.save(dataDir + "conic_pyramid_raster_image_out_.png", options);

3.从CAD文档中删除CAD文件中的各种实体对象

com.aspose.cad.fileformats.cad.CadImage image = (com.aspose.cad.fileformats.cad.CadImage) com.aspose.cad.Image

.load("Input.dwg");

 

for (int i = 0; i < image.getEntities().length; i++) {

CadBaseEntity baseEntity = image.getEntities()[i];

if (baseEntity.getClass() == com.aspose.cad.fileformats.cad.cadobjects.CadArc.class) {

com.aspose.cad.fileformats.cad.cadobjects.CadArc arc = (com.aspose.cad.fileformats.cad.cadobjects.CadArc) 

 

baseEntity;

if (arc.getCenterPoint().getX() > 1e10) {

// cadImage.RemoveEntityAt(i);

image.removeEntity(baseEntity);

i--;

}

}

}

 

image.updateSize();

 

// Create an instance of CadRasterizationOptions and set its various

// properties

com.aspose.cad.imageoptions.CadRasterizationOptions rasterizationOptions = new 

 

com.aspose.cad.imageoptions.CadRasterizationOptions();

rasterizationOptions.setBackgroundColor(com.aspose.cad.Color

.getWhite());

rasterizationOptions.setLayouts(new String[] { "Model" });

 

rasterizationOptions.setPageWidth(1600);

rasterizationOptions.setPageHeight(1600);

 

rasterizationOptions.setCenterDrawing(true);

// Create an instance of PdfOptions

com.aspose.cad.imageoptions.PdfOptions pdfOptions = new com.aspose.cad.imageoptions.PdfOptions();

// Set the VectorRasterizationOptions property

pdfOptions.setVectorRasterizationOptions(rasterizationOptions);

 

image.save("Output.pdf", pdfOptions);
