Search text in DWG and display only that entity in output

Aspose.CAD Product Family
1

Hello,

I just started trying Aspose CAD with .Net. My requirement is that I need to search for text across all entities and display only the entity that matches the search and output it as an image. I reviewed your docs and was able get some code to find all entities in dwg file, but wasn’t sure how I can export only a certain entity with text to an output image.

Please let me know if you need any more details.

Thank you!

@udaychekuru,

I suggest you to please try using following sample code on your end.

Aspose.CAD.Image cadImage = Aspose.CAD.Image.Load(sourceFilePath);

CadBaseEntity[] entities = cadImage.Entities;
List<CadBaseEntity> filteredEntities = new List<CadBaseEntity>();

foreach (CadBaseEntity baseEntity in entities)
{
    // selection or filtration of entities
    if (baseEntity.TypeName == CadEntityTypeName.TEXT)
    {
        filteredEntities.Add(baseEntity);
    }
}

cadImage.Entities = filteredEntities.ToArray();

// 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;

// Set Auto Layout Scaling
rasterizationOptions.AutomaticLayoutsScaling = true;

// Create an instance of PdfOptions
Aspose.CAD.ImageOptions.PdfOptions pdfOptions = new Aspose.CAD.ImageOptions.PdfOptions();

// Set the VectorRasterizationOptions property
pdfOptions.VectorRasterizationOptions = rasterizationOptions;

String MyDir =  "result_out.pdf";

// Export the CAD to PDF
cadImage.Save(MyDir, pdfOptions);
