@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 a some improvements. Namely it does not support
delaying the screenshot, selecting image quality or creating
thumbnails. Such operations is 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.
