How to convert between mat and byte 888.
Emgu cv convert mat to inputarray.
Image gray byte image bitmapextension toimage bitmapimage bitmap bitmapimage image tobitmap.
The get property provide a more efficient way to convert image gray byte image bgr byte and image bgra byte into bitmap such that the image data is shared with bitmap.
In 3 0 release emgu cv has adapted to use the mat class as a result.
You can use also for mat type remember to use nuget emgu runtime window or you can t use this library using emgu cv.
I called the method with an empty mat and a mask for both cpu and gpu.
The equivalent of cv mat.
If some of the input arrays may be empty pass cv noarray or simply cv mat as you probably did before.
If you change the pixel value on the bitmap you change the pixel values on the image object as well.
The doc of mat copyto void mat copyto outputarray m inputarray mask const says.
If you look at its implementation you will find that it supports not only std vector mat but also types like mat matx std.

In fact the method void inputarray getmatvector std vector mat mv const is not documented at all.
The image class is still available in this release for backward compatibility reason.

Emgu cv is a cross platform net wrapper to the opencv image processing library.
When you see in the reference manual or in opencv source code a function that takes inputarray it means that you can actually pass mat matx vector t etc.
If you are interest in using image class you can checkout.
When the operation mask is specified and the mat create call shown above reallocated the matrix the newly allocated matrix is initialized with all zeros before copying the data.
See above the complete list.
