Mouse position in image information not updating correctly

[ergwser]

Hi All,

My application loads images and then processes them. Those image sizes are different.

My problem is, the mouse position (in pixels) in image information is not updating currently, always one image behind.

The test vi is attached. Steps to reproduce it:

1 pick up two grayscale images, whose image size is very different.

2 on FP, point the image path to where two mages are located.

3 run the vi, put cursor on image indicator.

4 check the mouse position in image information bar.

Any idea?  Thanks a lot for helping.

Hi Anne,

What version of LabVIEW and the Vision Development Module are you using?

It seemed to work fine for me.

Have a great day,

Hi Chris,

My Labview is 8.5.1 and Vision is 8.5.

Thanks for your response.

Hi ergwser,

I checked in LabVIEW 8.5.1 and it appeared to work correctly.

However, I did notice that in both versions of LabVIEW, the cursor location did not update unless the mouse was moved.  This is expected behavior.  The cursor box does not update the location unless an event, like the mouse being moved, occurs.

Have a great day,

Hi Chris,

Thanks for your reply.

I saw the same as your abservation. However, it's not right,  and really confusing and misleading when different size images are loaded and no other event occurs and cursor location is not updated.

Is there a easy way to work around?

Thanks,

Anne
