BLITBLT(9.1) BLITBLT(9.1) 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 follows: choose layer A bull's eye cursor appears. Clicking but- ton 3 with the cursor inside a layer (cf. 3pi(9.1)) selects it for subsequent manipu- lation. 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 rectangle. run/halt The terminal process in the selected layer is continued 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 excluding the blitblt layer itself, is selected. write file The portion of the screen previously selected and prepared 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 (default) 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 bit- map on its standard input. | command The selected portion of the screen is sent BLITBLT(9.1) BLITBLT(9.1) to the command specified by the -p option (default bcan.) exit Must be confirmed by clicking button 3 in response to the skull cursor.

If a pipe request fails, the blitblt layer becomes unusable.
