Usage examples

CADNET-240 Support DWF format Export to BMP

 string fileName = GetFileFromDesktop("APFH Floor Plan.dwf");

using (Aspose.CAD.Image image = Aspose.CAD.Image.Load(fileName))

{

BmpOptions bmpOptions = new BmpOptions();

var dwfRasterizationOptions = new DwfRasterizationOptions();

bmpOptions.VectorRasterizationOptions = dwfRasterizationOptions;

dwfRasterizationOptions.CenterDrawing = true;

dwfRasterizationOptions.PageHeight = 500;

dwfRasterizationOptions.PageWidth = 500;

dwfRasterizationOptions.Layouts = new string[] { "Model" };

// export

string outPath = fileName + ".bmp";

image.Save(outPath, bmpOptions);

}

CADNET-240 Support DWF format Export to PDF

 string fileName = GetFileFromDesktop("APFH Floor Plan.dwf");

using (Aspose.CAD.Image image = Aspose.CAD.Image.Load(fileName))

{

var pdfOptions = new PdfOptions();

var dwfRasterizationOptions = new DwfRasterizationOptions();

pdfOptions.VectorRasterizationOptions = dwfRasterizationOptions;

dwfRasterizationOptions.CenterDrawing = true;

dwfRasterizationOptions.PageHeight = 500;

dwfRasterizationOptions.PageWidth = 500;

dwfRasterizationOptions.Layouts = new string[] { "Model" };

// export

string outPath = fileName + ".pdf";

image.Save(outPath, pdfOptions);

}

CADNET-197 Add support for DXF and DWG file formats in FileFormat enumeration. Difference of return value of Image.GetFileFormat method for DWG and DXF (DXF goes with DXF prefix)

 var dxf = GetDxfFile(@"AllEntities5.dxf");

var dwg = GetDwgFile(@"APFH Floor Plan (DWG).dwg");

var dxfFormat = Image.GetFileFormat(dxf); // Aspose.CAD.FileFormat.DXFCadR2010

var dwgFormat = Image.GetFileFormat(dwg); // Aspose.CAD.FileFormat.CadR2004

CADNET-68 Support MLeader entity for dwg format MLeader entity
