System.AccessViolationException while construct Mat using EmguCV

Question

what I need is an Emgu.Cv.Mat. Due to I have an Bitmap I want to pass his information to this Mat instance.

Here is my code:

//the real file is not stored on the harddrive. this is for demonstration only.
Bitmap fileBmp = new Bitmap(@"C:\Users\my\Desktop\file1.PNG"); 

.

//generating an Image from it works pretty fine as well. Even displaying it works great.
Image<Bgr, Byte> image = new Image<Bgr, Byte>(fileBmp);

.

//But I'm not able to generate a Mat with it. Not using the Bitmap
Mat mat1 = new Mat(new int[] { fileBmp.Width, fileBmp.Height }, DepthType.Cv8S, fileBmp.GetHbitmap());

//... and not using the Image
Mat mat2 = new Mat(new int[] { fileBmp.Width, fileBmp.Height }, DepthType.Cv8S, image.Bitmap.GetHbitmap());

I keep getting an

System.AccessViolationException

If I read either mat1.Bitmap property or mat2.Bitmap property (all other properties looking fine). What is wrong with my code?

Any suggestions how I can pass the "graphic information" to an Mat using EmguCv?

One again: using new Mat(@"C:\Users\my\Desktop\file1.PNG") is not possible due to the bitmap is not stored on the hard drive.

Answer 1

Image<Bgr, Byte> image = new Image<Bgr, Byte>(fileBmp);
Mat mat1 = image.Mat;
