Snagit image capture - ambiguity when defining a custom-size selection area

Sometimes, the screenshot you're taking really does have to have pixel precise boundaries. That little floating magnifier is fantastic for this sort of thing, but it's not perfect.

Suppose, for the sake of example, I have a sharp black square on a white background. Say I want to take a capture that contains all of the black of the square and none of the white of the background, to a pixel. I boot up Snagit and drag out a boundary, and the floating magnifier shows me this:



The fact that those yellow lines are a pixel wide leaves me asking two questions:

(1) Is the screen shot going to include whatever is "underneath" the yellow lines?
(2) What actually is under the yellow lines? Am I capturing all of the black? Am I missing some of it out? Important questions.

Proposition: instead of being "1px" wide/high, the yellow target lines could be the size of the grid-lines that are already visible in the magnifier, and just coloured yellow.
Or really any other solution that resolves the ambiguity highlighted by (1) and (2).

So, I've never had an issue with the magnifier myself, what you see is what you get.
Once you're close to your target you can move the magnifier one pixel at a time with your arrow keys for a precise selection. So when you sneak up on a black line or anything else for that matter, it's pretty easy to see if your going to be covering anything up.

However, that doesn't mean there isn't room for improvement. TechSmith could incorporate cross-hairs much like the ones that are used without the magnifier.
I created a mock-up of what I think it might look like.
