Convert image to CAD file (DWG or DXF)

Question

I have a .NET C# program that needs to convert an image (be it BMP, JPEG, PNG) into an AutoCAD file (DWG or DXF). I've tried several ways mentioned here in other forums, but without success. I tried Aspose but there they only import DWG and don't convert to DWG.

Could anyone help me with some approach to this conversion or an API for .NET ?

I tried to convert using Aspose's API, with this link; I tried the exact same code but it doesn't seem to work because the generated DXF is empty.

The most promising approach for my .NET C# program seems to be via Aspose, but as I mentioned, I was unsuccessful.

• Ryan Marques: I tried the below code available in Aspose library but it saves an empty file, there is no content in output.dxf using Aspose.Imaging; usingSystem; using System.IO; using System.Text; using System.Collections.Generic; string templatesFolder = @"c:\Users\USER\templates\"; using (var image = Aspose.Imaging.Image.Load(Path.Combine(templatesFolder, @"template.bmp"))) { var exportOptions = new Aspose.Imaging.ImageOptions.DxfOptions(){ TextAsLines = true,ConvertTextBeziers = true}; image.Save(Path.Combine(templatesFolder, "output.dxf"), exportOptions); }
• 500 - Internal Server Error: Reading your question again, you do realize that dwg/dxf is not an image format as such but a CAD format, right? I mean, it can have elements in it that are bitmapped images, but that's not what the overall format is about.
• Ryan Marques: Okay, so basically I should convert the image to a vectorized type (SVG for example) and then upload it to a CAD file?

You can try something like this with Aspose.CAD library:

using (Image cadImage = Image.Load("input.png"))
{
 cadImage.Save("output.dxf", new DxfOptions());
}
