I need to do some testing on an app that involves checking the size of elements. Just a rough test to begin with and then if something looks to fail, I can get more detailed.
I want to trigger a macro that temporarily changes the mouse cursor to an image that I define and then switch it off. I have searched the existing macros for 'cursor' and get no results. Is there a way that I can achieve this, do you think?
Note that I want to be able to run this regardless of what app might be running (will be using to test web apps, native apps).
How are you checking "size"? IIRC there's been a few macros posted that would allow you click points A and B and get the pixel distance between them, the size of rectangle they create, and similar.
It would be nice if you could switch your pointer to/from a "template image" on the fly, for instant comparisons, but Apple have made that kind of customisation harder and harder. Last utility I can remember for such is Mousecape, which we used to recommend to lefties, but it hasn't been updated recently so I don't know if it will work on Ventura or with Apple silicon.
If you are happy with a square or rectangle, you could try something like this -- not ideal, but an approximation of what you seem to be after. As set, press F8 to trigger and keep that key held down to maintain the (unfortunately flickering) rectangle as you move the pointer around:
