       xzoom - magnify part of X display, with real-time updates

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.

       Xzoom allow you to resize it's window at any time.

       When xzoom is iconified it simply waits to get deiconified.

       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.
