EXAMINE(9.1) EXAMINE(9.1)
NAME
examine - examine pixel values interactively
SYNOPSIS
fb/examine [ input ]
DESCRIPTION
Examine displays an approximation of its argument picture
file (default standard input) in the middle of the screen or
window and waits for mouse input. Button 1 selects pixels,
whose coordinates and values are written to standard output.
Button 2 refreshes the display, which can be overwritten by
examine's output. Button 3 exits.

BUGS
For compatibility with other programs, buttons 2 and 3
should pop up menus. But single-item menus are silly, and
it's too much to have two of them.
