Extract an image to another

[Johnson]

Did any function can extract an image to an area of another image and also can assign start point?

Are you looking for a general way to do this in Visual Basic or a way to do this with the IMAQ/Vision APIs? If the former, you can do this with with the Win32 BitBlt function, or Graphics.DrawImage if you're using VB.NET. If the latter, you would get a better answer to this question in the Vision forum.

Sorry! I am a IMAQ user. And I try to find an answer before. But I still can't found anything about my question.
In fact, I want to combine some image. Now, I use a stupid way to slove it. First, using ImageToArray function to generate 2D matrix. Then, copy the matrix to another large matrix. Finally, I will get all data about these images and use ArrayToImage function to generate an image. But it's spend much times.
