F XMAGnifier, MOTIF_TOYS, Magnifying glass attached to the mouse pointer  I         This demo opens a magnifying glass attached to the mouse pointer. I         It will enlarge any area it  covers  when  a  MB  is  pressed  by I         opening  a  magnified  window.    Once in  it's  enlarged  window I         pressing  MB1  causes pixel information for the pixel  under  the I         pointer  to be displayed.  Pressing MB2 or MB3  in  this  window, I         closes  it  and returns you to the magnifying glass.   It  has  a I         various command line options to control the size of the magnifer, 6         the level of magnification, etc, listed below.                                           ** NOTE **  I         You must have the logical  name DEMOS defined to point to the top I         level directory that contains the XMAG  directory.    All command I         procedures rely on this being defined.   For  example  if all the I         XMAG files are in WORK:[SMITH.XMAG] then you need  a logical name          defined as follows:          6         $ DEFINE/SYSTEM/EXECUTIVE DEMOS WORK:[SMITH.]   H         **  Ensure you include the "." after the last directory name  **                           To build... I         -----------------------------------------------------------------                          %         $ @DEMOS:[XMAG]BUILD_XMAG.COM   I         This will  build  either a OpenVMS VAX or OpenVMS AXP image based *         on what architecture it is run on.                                   To run... I         -----------------------------------------------------------------   %         $ @DEMOS:[XMAG]START_XMAG.COM          I         This  will  start  up  the  appropiate  architecture  version  of          XMAG.                                                XMAG options... I         -----------------------------------------------------------------   +         $ XMAG :== "$ DEMOS:[XMAG]XMAG_AXP"          $ XMAG -h   8         Usage: demos:[xmag]xmag_axp.exe;5 [-options ...]           Where options include:  9         -display displaystring        X server to contact F         -geometry geomstring          size and location of enlargementN         -source geomstring            size and location of area to be enlargedO         -mag magfactor                integral amount by which area is enlarged <         -bw pixels                    border width in pixels2         -bd color                     border colorG         -bg colororpixelvalue         background color or %pixel number P         -fn fontname                  name of font for examining enlarged pixelsO         -z                            grab server during dynamics and XGetImage   F         Options may be abbreviated to the shortest unambiguous prefix.
