Image in the "Image Display" control is ovewritten

[Mic_Scale]

Hello,

I have built a picture using a 2D Array and then converted it by using the "Array to Image" (Vision Module) and then displayed it using the "Image Display" Control and tried also the "IMAQ WindDraw" vi. The problem is that when I loose focus with the mouse, or open another window, the picture disappears or parts of it are overwritten and are not updated back when I come back to the Image.

Is there a way to set the image so that it won't be affected by other actions, and will remain stable ?

Thanx

This may happen because after sending the data to the image display you have used inadvertently the IMAQ Dispose function.

The information in this post and this other post may be of use to you in understanding this.

Basically an IMAQ image display is globally accessible in nature and it is easy to update or overwrite it from left-field operations if you are not careful.
