I've been wondering if there is any image editor out there (or maybe a plug-in for an existing image editor), preferably freeware, where the user can press or hold a key to activate a zoom reticle over a very localized area.
The point being: while helping my users via remote control, I often want to take screenshots of a specific window to document the issues they're having, however I can't exactly do that with Alt+Printscreen due to the active window on my end being the remote control software's.
So what I do is take screenshots of my whole monitor, which I then have to crop as I want to show only the relevant window(s).
However, I'm a bit of a maniac when it comes to cropping, and as much as possible, I want to avoid having a few lines of pixels that aren't part of the window showing on the edges, or the window's picture to have missing pixels — yeah, I should probably take some kind of medication for that ^^'.
So I use the zoom feature from whichever picture editor I have at hand, so I can see the individual pixels while making my rectangular selection, but then the whole picture is zoomed in and unless it's actually quite small, I can't see both the top left and bottom right corner at the same time, which is annoying.
Thus the idea of a zoom reticle which could be activated and deactivated with a keypress (or by holding a key).
I did try using Windows' magnifying glass, but its zoom is blurry and not "pixel perfect" — I guess they wanted it to have some kind of antialiasing.
Does anyone know of an image editor which includes that feature, or has/could have a plug-in which does that?
Failing that, maybe an alternate magnifying glass software which could be enabled and disabled from the keyboard (so I don't need to move the mouse to disable it), and if possible would even allow slowing the mouse movement when it's active? Obviously, it should allow to see exactly where the mouse cursor is.
If not, then I guess that could be a coding snack…
