Using non-square template images

[Err]

Is there any possibility of using non-square templates in IMAQ Match Color Pattern? For example, I need to find predefined circle in the image, but in case of using it as a template, it will be surrounded with zero pixels. Would it influence on searching results?

To do color pattern matching, you will always have a rectangular template image.  Depending on your application you may want to try doing geometric matching to limit your image to only that portion that you are wanting to search through.

Thank you, but I think I found solvation. I use image mask of necessary shape, and during the  matching apply "ignore black".
