MOVIE(1)

NAME

movie − algorithm animation

SYNOPSIS

movie [ -d ] [ files ... ]

DESCRIPTION

Movie converts a ‘movie script’ into an internal representation, then displays it in a window. Or, if the input file is already in the internal representation format, the conversion step is skipped. The -d option says to leave the internal representation around in a file with the same name as the input file, with the suffix (if any) replaced by .i. If no file names are given, standard input is used. If more than one file name is given, they are each animated in turn.

Button 1 stops and starts the movie; button 2 adjusts view sizes and selects clicks; button 3 sets various parameters. The ‘new file’ option on the button 3 menu prompts for another file to display; that file must be in internal representation format.

Movie scripts

A movie consists of multiple independent views, each presented as a rectangular sub-window. If no view statements appear, there is a single implicit view def.view. Any text or geometrical object may be labeled with a name and colon. Labels and coordinates are local to views. A recurring label erases the previous object with that label.

Comments follow #; blank lines are ignored.

text options x y string
Text is centered and medium size by default; options: one of center ljust rjust above below, and one of small medium big bigbig. A leading quote is stripped from string, as is a trailing quote if a leading one is present.

line options x1 y1 x2 y2
Lines are solid by default; options: one of fat fatfat dotted dashed and one of -> <- <->.

box options xmin ymin xmax ymax
A box may be filled.

circle options x1 y1 radius
Radius is measured in the x dimension. A circle may be filled.
