No update of imaq winddraw

[thomas-j]

Hello! I am processing a part of an image (marked with ROI) and displayed in a window. After the processing I put the new data into the old image but there is no update of the window. When I move the mouse and it hits the ROI then suddenly the window updates and I see my processed image!? I have tried to both do a new winddraw and a new windshow but it does not help.

Thomas-
Try using the IMAQ WindZoom VI with a zoom factor of 1. This will essentially redraw the window, but will not change anything about it.

If this also does not work, there may be something else wrong. You can post a small piece of your code that exhibits this behavior to take a look at.

Hope this helps.

Thank you very much!I have not tried your idea. The problem was because I had one Vi that used a lot of computer time. My program worked correctly after I slowed that vi down!
