STP Drawings

Exporting STP Format To PDF

Aspose.CAD for .NET allows developers to export an STP file to PDF format. STP to PDF conversion approach works as follows:

1. Load STP drawing file using the Image.Load factory method.
2. Create an object of the CadRasterizationOptions class and set the PageHeight & PageWidth properties.
3. Create an object of the PdfOptions class and set the VectorRasterizationOptions property.
4. Call Image.Save while passing an object of PdfOptions as the second parameter.

Sample Code

string inputFile ="file.stp";            
using (Image image = Image.Load(inputFile))
{
    // Initialize  PdfOptions class object
    PdfOptions options = new PdfOptions();
    
    CadRasterizationOptions cadRasterizationOptions = new CadRasterizationOptions();
    
    cadRasterizationOptions.PageHeight = 500;
    cadRasterizationOptions.PageWidth = 500;
    
    options.VectorRasterizationOptions = cadRasterizationOptions;

    // Export STP to PDF
    string outPath = "output.pdf";
    image.Save(outPath, options);
}
