When I open a .dwg file using viewer the size of the image is very small and opened at the right corner
I am trying to open a file of size 9.5 mb.
I am attaching the imageAsposeConverted.png (13.0 KB)
I have observed your comments. Can you please share source file along with sample code and Aspose.CAD version you used on your end so that we may further investigate to help you out.

Hi Adnan
I am using product version 18.8
I am attaching the file and sample code in the controller as well
We are using a mvc web solution.
The loading is very slow and image is very small and opened at the right corner
using (Aspose.CAD.Image image1 = Aspose.CAD.Image.Load(file.InputStream))
{
Aspose.CAD.ImageOptions.CadRasterizationOptions rasterizationOptions = new Aspose.CAD.ImageOptions.CadRasterizationOptions();
ImageOptionsBase options = new Aspose.CAD.ImageOptions.PngOptions();
options.VectorRasterizationOptions = rasterizationOptions;
urlPath = System.IO.Path.Combine("~/Upload/" + Guid.NewGuid().ToString() + ".png");
absolutePath = Request.MapPath(urlPath);
image1.Save(absolutePath, options);
}
Please unzip the attached file and get the .dwg file in it
Thank you for providing the source information. Can you please provide the generated PNG file for reference so that we may add ticket in our issue tracking system for resolution.

The file size after conversion is very huge as well.
I suggest you to please try using following sample code using latest Aspose.CAD for .NET 18.8 on your end. The generated Saved.png (8.0 KB) has also been attached.
