SYNOPSIS

       xzoom

       xzoom [args]

       xzoom [-x ] [-y ] [-mag magnification]
             [-geometry 'width size' x 'height size']

DESCRIPTION

       Xzoom  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.

       Use commands to change rotation, zoom or mirror the image.

OPTIONS

       -d <displayname>, -display <displayname>
              The name of the display to use.

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

       -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 magnification to get the size of xzoom's window. If
              these  dimensions  are  given  separately  (by  use  of -geometry) then an error is
              reported.

       -x     Mirror horizontally.

       -y     Mirror vertically.

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

COMMANDS

       +      Increase magnification value by 1.

       -      Decrease magnification value by 1.

       x      Mirror the display image horizontally.

       y      Mirror the display image vertically.

       z      Rotate 90 degrees counter-clockwise.

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

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

       d      Sets the delay between frame updates. Built-in delays are 200, 100, 50,  10  and  0
              ms.

       q      Quit.

       Arrow keys
              Scroll  the  zoomed area 1 pixel in the direction of the arrow.  if the control key
              is pressed the zoomed area will scroll 10 pixels.

       Mouse buttons
              To set the location of the magnified area,  click  the  left  mouse  button  inside
              xzoom's  window  and  then move it (keep the button pressed) to the place which you
              want to see magnified.

EXAMPLES

       xzoom -mag 5
              # Open xzoom with magnification 5.

       xzoom -mag 2 -geometry 800x400
              # Open xzoom with magnification 2 and windows size 800x400.

       xzoom -x
              # Open display flipping right and left.
