@chapter Overview

@command{scrotty} is a simple command for taking a screenshot
of your framebuffers. It can be used to take a screenshot of
your @sc{TTY} session, but it cannot take a screenshot of your
@sc{X} session.@footnote{Unless it is for some reason is
rendered on the framebuffer.}

@command{scrotty} is designed after @command{scrot}, but
includes some improvements. Namely it does not support
delaying the screenshot, selecting image quality or creating
thumbnails. Such operations are left to be done by the user
with the option @option{--exec} and a utility such as
@command{convert} (from the ImageMagick project.)

@command{scrotty} reads the data stored in the framebuffers,
convert it the @sc{PNM} images and pipes it to @command{convert}
to create @sc{PNG} images.

@command{scrotty} can appear to be a bit slow. This is not
@command{scrotty}'s fault. Reading a framebuffer, even if
not processing the data, takes time. In fact, screenshots
for @sc{X} are slow too.
