I created a screenshot and then I added some arrows and text to it. For some reason, when I saved the image, the arrows and text were blurry.
I tried doing the same thing in Snagit and the output wasn't blurry.
Also, I couldn't figure out how to resize the canvas (so I could add the text outside
of the screenshot), so I pasted the screenshot into Paint and then
opened that in Screenshot Captor.
