-mag[nification] magnification-ratio
-magnification option specifies the ratio of pixels per workspace unit at which the new G2 process displays workspaces at full scale. Specify a decimal value in the range 0.50 to 2.66. If you specify neither the
-magnification option nor the -x-magnification or -y-magnification options, the new G2 process uses a -magnification setting of 1.0. For more information about using the -magnification, -x-magnification, and -y-magnification options, see Specifying the Resolution and Magnification.
Special Considerations
Alternatively, for a display device that supports distinct settings for horizontal and vertical resolutions, you can use the -x-magnification and -y-magnification command line options to specify distinct horizontal and vertical magnifications. However, don't combine the -magnification argument with either the -x-magnification or -y-magnification options. Example
This command starts a G2 process that displays workspaces at full scale at the magnification of two pixels per G2 workspace unit:
g2 -magnification 2.0
