Convertir DWG en PDF avec des coordonnées
Comment convertir DWG en PDF avec des coordonnées
Aspose.CAD offre la fonctionnalité de charger le fichier AutoCAD DWG et de l’exporter au format PDF en fournissant des coordonnées. Pour cela, l’API fournit la classe CadVportTableObject. La classe CadVportTableObject est utilisée pour spécifier les coordonnées pour la conversion.
L’exemple de code ci-dessous montre comment convertir un fichier DWG au format PDF en fournissant des coordonnées à l’aide d’Aspose.CAD pour .NET en C#.
// For complete examples and data files, please go to https://github.com/aspose-cad/Aspose.CAD-for-.NET | |
// The path to the documents directory. | |
string MyDir = RunExamples.GetDataDir_DWGDrawings(); | |
string sourceFilePath = MyDir + "visualization_-_conference_room.dwg"; | |
using (CadImage cadImage = (CadImage)Image.Load(sourceFilePath)) | |
{ | |
CadRasterizationOptions rasterizationOptions = new CadRasterizationOptions(); | |
rasterizationOptions.Layouts = new string[] { "Model" }; | |
rasterizationOptions.NoScaling = true; | |
// note: preserving some empty borders around part of image is the responsibility of customer | |
// top left point of region to draw | |
Point topLeft = new Point(500, 1000); | |
double width = 3108; | |
double height = 2489; | |
CadVportTableObject newView = new CadVportTableObject(); | |
newView.Name = new CadStringParameter(); | |
newView.Name.Init("*Active"); | |
newView.CenterPoint.X = topLeft.X + width / 2f; | |
newView.CenterPoint.Y = topLeft.Y - height / 2f; | |
newView.ViewHeight.Value = height; | |
newView.ViewAspectRatio.Value = width / height; | |
for (int i = 0; i < cadImage.ViewPorts.Count; i++) | |
{ | |
CadVportTableObject currentView = (CadVportTableObject)(cadImage.ViewPorts[i]); | |
if (cadImage.ViewPorts.Count == 1 || string.Equals(currentView.Name.Value.ToLowerInvariant(), "*active")) | |
{ | |
cadImage.ViewPorts[i] = newView; | |
break; | |
} | |
} | |
// Create an instance of PdfOptions | |
Aspose.CAD.ImageOptions.PdfOptions pdfOptions = new Aspose.CAD.ImageOptions.PdfOptions(); | |
// Set the VectorRasterizationOptions property | |
pdfOptions.VectorRasterizationOptions = rasterizationOptions; | |
MyDir = MyDir + "ConvertDWGToPDFBySupplyingCoordinates_out.pdf"; | |
//Export the DWG to PDF | |
cadImage.Save(MyDir, pdfOptions); | |
