Accuracy of image ROI

[gabi_hor]

Hi 

I am using the point tool of image ROI to indicate a point on an image. When the magnification is float number, the ROI location is not accurate.

Try the attached vi. Try to point to the center of the black cross in the image.

As long as the magnification isn't a whole number the green cross miss the black cross.

Regards

Hi

Leave the magnification equal to 2.1, try now to do it.

Hi Gabi:

How accurately are you trying to place the cross?  I got the crosses to overlap although it isn't completely centered.

You know, it really isn't necessary to keep popping in messages randomly thanking people for information.  Also, you really don't need to tell us you are new to the forums and you are from London.  (or is it Canada today).  By the quality of the posts, we've already figured out you're new.
