MUG(1)                      General Commands Manual                     MUG(1)

NAME
       mug - convert an image to a face icon

SYNOPSIS
       mug [ file ]

DESCRIPTION
       Mug reads a Plan 9 image(6) from file (or standard input if there is no
       file)  and  displays  a  working version of the icon a gray ramp, and a
       larger image (the ‘crop box'), all derived from file.   Selecting  from
       the  button-3  menu  will  write the icon in face(6) format to standard
       output.

       Imagine a 3x3 grid on the crop box.  You can move an edge or corner  of
       the  box  by putting the mouse in the corresponding section of the grid
       and dragging.  Dragging in the middle box in the  grid  translates  the
       crop box.  The mouse cursor changes to tell you where you are.

       The  bar  in the gray ramp controls the map from picture gray levels to
       the output levels.  The values along the bar are mapped  to  0  through
       255  in  the  output.   You can move the bar vertically by grabbing the
       midsection or adjust the width by grabbing an endpoint.

       The current icon is shown in the  bottom  left  corner,  surrounded  by
       eight  small  empty  boxes.   You  can save the settings as they are by
       dragging the current icon into one of the other boxes.  You can restore
       the settings by dragging an icon from one of the periphery  boxes  into
       the middle.

EXAMPLES
       Convert a JPEG image into a face icon.
