NAME

       mag - computes fontsizes and magsteps

SYNOPSIS

       mag [-Rdpi] magstep . . .

       mag [-r] [-Rdpi] fontsize . . .

DESCRIPTION

       delim $$ This tool calculates fontsizes given magsteps.	TeXfonts are provided as true sized fonts or as magnifications.  The fontsize of a
       true sized font equals the resolution of the printer (ex.  300).  The fontsize of a font magnified $n$ magsteps equals:	1.2  sup{n}  times
       300 delim off rounded to its nearest integer value.  Fontnames for TeX fonts normally consists of the name (cmr), pointsize (10), type (pk)
       and fontsize (360), for example: cmr10.360pk.

EXAMPLES

       The result of mag -R240 -2 0 0.5 1 will be:

	      167 240 263 288

       The inverse function is computed with the -r option. The result of mag -r -R240 167 240 263 288 will be the fontsteps:

	      -2 0 0.5 1

       The UNIX shells allow command substitution. One can write:

	      mag -r -R240 `mag -R240 -2 0 0.5 1`

NAME

       xzoom- magnify parts of the screen

SYNOPSIS

       xzoom [ -display displayname ] [ -mag mag [ mag ] ] [ -x ] [ -y ] [ -xy ] [ -geometry geometry ] [ -source geometry ] [ -mouse ] [ -multi ]

DESCRIPTION

       The  xzoom program displays  in its window a magnified area of the X11 display.	The user can  interactively  change  the  zoomed area, the
       window size, magnification (optionally different magnification for X and Y axes) or rotate  or  mirror  the image.

OPTIONS

       -display displayname
		      The name of the display to use (not very useful).

       -mag mag [ mag ]
		      What  magnification  to  use. If two number arguments are supplied the first is used  for  X  magniications and  the  second
		      is used for Y magnification.  Magnification should be greater than 0.

       -x	      Mirror horizontally.

       -y	      Mirror vertically.

       -xy	      Exchange X and Y axes  before  any  magnification  is performed.

       -geometry geometry
		      Size and position xzoom's window.

       -source geometry
		      Size   and  position  the initial source area which is magnified.  The dimensions of this  area  are  multiplied by the mag-
		      nification to get the size of xzoom's window. If these dimensions are given separately (by use of -geometry ) then an  error
		      is reported.

       -mouse	      Interactively update the magnified area,by moving the mouse pointer.

       -multi	      Used when the display specified is a multi-visual.

WINDOW COMMANDS

       Apart from the command line arguments, xzoom can be operated with the following Window commands also.

       + : Zoom in

       - : Zoom out

       x : Flip right and left

       y : Flip top and bottom

       z : Rotate 90 degrees counter-clockwize

       w :  Next '+' or '-' only change width scaling

       h :  Next '+' or '-' only change height scaling

       d : Change delay between frames

       q : Quit

       Arrow keys : Scroll in direction of arrow

       Mouse button drag : Set top-left corner of viewed area
