Is there a C# code sample using ImageToArray and ArrayToImage?

[mpu]

I am looking for a C# code sample using the CWImaqImage methods ImageToArray() and ArrayToImage().

When I try the following:

using NationalInstruments;

using

NationalInstruments.CWIMAQControls;

CWIMAQImage srcImage = new CWIMAQImage();

CWIMAQImage destImage = new CWIMAQImage();

byte[] bufferArray = new byte[640 * 480];

srcImage.SetSize(640, 480);

srcImage.Type =

CWIMAQImageTypes.cwimaqImageTypeU8;

srcImage.ArrayToImage((

Object)bufferArray);

...perform image processing operations -> destImage

bufferArray = (

byte[])destImage.ImageToArray(0,0,640,480)

I get a runtime exception when ArrayToImage() is called: COMException was unhandled by user code - "You have passed an invalid type into a parameter of a VARIANT type."

Any sample code using these two methods would be appreciated.

Hi mpu,

Unfortunately, I do not have a quick answer to this one. I am looking into this and will post back to this thread as soon as I have a answer for you.

Hi mpu,

I've attached an example of how to do this. To use this function, you do not need to pass an object but can pass an array of integers.

Does this make sense?
