Print images onto your terminal
imgcat prints images to your terminal screen. Yes, indeed it does. By default, the image is printed at the full width and colour depth detected for your terminal. These can be overridden using -w to adjust the maximum width or -R to prevent resizing, even if the image is too big to fit in the terminal; and -d to explicitly the set color depth.
If the output stream is not a terminal (that is, output is redirected to a file, or piped into another program), then the image is not resized to the size of the terminal. It does, however, uses the color depth of terminal set in the TERM environment variable. Overriding both width and color depth still work.
