Hello, I’m developing a program using C# Windows Forms. What I want to do is to drag and drop only .dwg and .dxf files into a DataGridView and display the corresponding file’s images in each row. I have accomplished everything so far, but I have a few issues. I’m unable to change the drawing color of the image added to the PictureBox, and I would like to retrieve the actual dimensions (maximum width and height) of the files I upload. Thank you in advance for your support.

You’re already changing the background color with viewOptions.CadOptions.BackgroundColor. Please clarify if this setting does not work as expected or if you’re trying to do something else.

You can use GetViewInfo method to get the image size

using (var viewer = new Viewer("house-plan.dwg"))
{
    var viewInfoOptions = ViewInfoOptions.FromPngViewOptions(viewOptions); 
    var viewInfo = viewer.GetViewInfo(viewInfoOptions);

    foreach (var page in viewInfo.Pages)
    {
        Console.WriteLine($"Page {page.Number}, width: {page.Width}, height: {page.Height}");
    }
}

Sir, in the sample image, we changed the drawing color to purple in Inventor and added the actual dimensions of the drawing. What I want is to simply change the drawing color from gray to purple and write the dimensions in the DataGridView.

You can use page.Width and page page.Height for:

dimensions in the DataGridView.
