If you experience errors, when you try to download a file, make sure your network policies (enforced by your company or ISP) allow downloading ZIP and/or MSI files.
Se agregó la capacidad de obtener el tamaño de página y las dimensiones de página del archivo DWF.
DWF
// The path to the documents directory. string MyDir = RunExamples.GetDataDir_DWFDrawings(); string sourceFilePath = MyDir + "blocks_and_tables.dwf"; string extension = Path.GetExtension(sourceFilePath); using (DwfImage image = (DwfImage)Aspose.CAD.Image.Load(sourceFilePath)) { foreach (var page in image.Pages) { var layout = page.Name; System.Console.WriteLine("Layout= " + layout); using (FileStream fs = new FileStream(MyDir + "layout_" + layout + ".jpg", FileMode.Create)) { JpegOptions jpegOptions = new JpegOptions(); CadRasterizationOptions options = new CadRasterizationOptions(); options.Layouts = new string[] { layout }; double sizeExtX = page.MaxPoint.X - page.MinPoint.X; double sizeExtY = page.MaxPoint.Y - page.MinPoint.Y; if (page.UnitType == UnitType.Inch) { options.PageHeight = CommonHelper.INtoPixels(sizeExtY, CommonHelper.DPI); options.PageWidth = CommonHelper.INtoPixels(sizeExtX, CommonHelper.DPI); } else if (page.UnitType == UnitType.Millimeter) { options.PageHeight = CommonHelper.MMtoPixels(sizeExtY, CommonHelper.DPI); options.PageWidth = CommonHelper.MMtoPixels(sizeExtX, CommonHelper.DPI); } else { options.PageHeight = (float)sizeExtY; options.PageWidth = (float)sizeExtX; } jpegOptions.VectorRasterizationOptions = options; image.Save(fs, jpegOptions); } } }
Se agregó la función de establecer la fuente alternativa predeterminada.
MTEXT
Se observó que durante la conversión de DXF a PDF, el MTEXT (texto múltiple) perdía transparencia. Este problema ya se ha resuelto.
DXF
PDF
El siguiente es un fragmento de código C# simple que convierte una capa específica del formato DXF al formato PDF a través de la API:
string MyDir = RunExamples.GetDataDir_DXFDrawings(); string sourceFilePath = MyDir + "conic_pyramid.dxf"; using (Aspose.CAD.Image image = Aspose.CAD.Image.Load(sourceFilePath)) { // Create an instance of CadRasterizationOptions and set its various properties Aspose.CAD.ImageOptions.CadRasterizationOptions rasterizationOptions = new Aspose.CAD.ImageOptions.CadRasterizationOptions(); rasterizationOptions.PageWidth = 1600; rasterizationOptions.PageHeight = 1600; // Add desired layers rasterizationOptions.Layers = new string[] { "LayerA" }; // Create an instance of PdfOptions Aspose.CAD.ImageOptions.PdfOptions pdfOptions = new Aspose.CAD.ImageOptions.PdfOptions(); // Set the VectorRasterizationOptions property pdfOptions.VectorRasterizationOptions = rasterizationOptions; MyDir = MyDir + "conic_pyramid_layer_out.pdf"; //Export the DXF to PDF image.Save(MyDir, pdfOptions); }
