DXF to SVG - How to fill generated shapes

Aspose.CAD Product Family
1

I want to export a DXF in SVG. The form in it is a closed shape, and I want to fill it with a color, so the shape is visible as a filled shape on a webpage, not just show the vectors only. I don’t see any option to do that. Is there a way to “close” the shapes in the SVG ?

To fill closed shapes when exporting a DXF file to SVG using Aspose.CAD, you can utilize the SvgOptions class, which allows you to specify various options for the SVG output. While the provided context does not explicitly mention filling shapes, you can achieve this by ensuring that the shapes in your DXF file are properly defined as closed paths.

Here’s a basic example of how to export a DXF file to SVG with the necessary options:

C# Example

using Aspose.CAD.ImageOptions;
using System;

namespace Aspose.CAD.Examples.CSharp.DWG_Drawings
{
    class ExportToSVG
    {
        public static void Run()
        {
            // Define the path to the DXF file
            string MyDir = RunExamples.GetDataDir_DWGDrawings();
            using (Image image = Image.Load(MyDir + "sample.dwg"))
            {
                var options = new SvgOptions
                {
                    TextAsShapes = true // This ensures text is converted to shapes
                };

                // Save the image as SVG
                image.Save(MyDir + "sample.svg", options);
            }
        }
    }
}

Java Example

import com.aspose.cad.Image;
import com.aspose.cad.imageoptions.SvgOptions;
import com.aspose.cad.imageoptions.svgoptionsparameters.SvgColorMode;

public class ExportToSVG {
    public static void main(String[] args) {
        // Define the path to the DXF file
        String dataDir = Utils.getDataDir(ExportToSVG.class) + "DWGDrawings/";
        Image image = Image.load(dataDir + "meshes.dwg");
        {
            SvgOptions options = new SvgOptions();
            options.setColorType(SvgColorMode.Grayscale); // Set color mode as needed
            options.setTextAsShapes(true); // Convert text to shapes

            // Save the image as SVG
            image.save(dataDir + "meshes.svg", options);
        }
    }
}

Additional Notes

  • Ensure that the shapes in your DXF file are defined as closed paths. If they are not, you may need to modify the DXF file to ensure that the shapes are closed before exporting.
  • The SvgOptions class provides various settings that can be adjusted to meet your specific needs, such as color modes and text handling.

By following the above examples, you should be able to export your DXF file to SVG with filled shapes visible on a webpage. If you need further customization or specific features, consider exploring the Aspose.CAD documentation for additional options.

Thanks for the answer.

I cannot ensure that the DXF are defined as closed paths, I have no control over that.

I tried with the options, but it change almost nothing.

Are there other options to control how the SVG is structured during the conversion ?

@laseo,
Hello,
could you please share the sample of such shape in DXF format?
