NAME
blitblt - make hard copy of screen image
SYNOPSIS
blitblt [ -p command ]
DESCRIPTION
Blitblt copies part or all of a jerq screen into a file or down a pipe
to a printer daemon. The program is menu driven off button 3 as fol‐
lows:
choose layer A bull's eye cursor appears. Clicking button 3 with
the cursor inside a layer (cf. 3pi(9.1)) selects it
for subsequent manipulation.
layer interior As above, but the border surrounding the layer is not
included.
flip border The border is changed from narrow to wide (or
vice versa) in the selected layer or rectangle.
reverse video The video is inverted in the selected layer or rectan‐
gle.
run/halt The terminal process in the selected layer is contin‐
ued or halted. This menu entry changes with the
layer's status.
sweep rectangle A rectangle cursor appears. The rectangle swept out
on button 3 becomes the selected area.
whole screen The entire screen, including border areas, but exclud‐
ing the blitblt layer itself, is selected.
write file The portion of the screen previously selected and pre‐
pared is written into a file or pipe. The filename is
typed in answer to a prompt appearing at the bottom of
the blitblt layer. Hitting return selects the (de‐
fault) name in parentheses. If the first character
typed is a `|' (pipe symbol), the remainder of the
line is taken as a shell command which will read the
bitmap on its standard input.
| command The selected portion of the screen is sent to the com‐
mand specified by the -p option (default bcan.)
exit Must be confirmed by clicking button 3 in response to
the skull cursor.

BUGS
Moving layers (e.g. clocks) result in broken images. Use the halt
function.
If a pipe request fails, the blitblt layer becomes unusable.
