# -gsize:

The size for reading in an EPS/PS image is set by the PostScript specials parameter. If the magnification of the dvi file is not 1000 (i.e., when
\mag=\magstep1
is in the TeX source), when the read-in size written in the PostScript specials is set to the size after magnification, the "-gsize:" switch is turned on (parameter set to ON or OFF, Property Sheets->[Graphic]).
In particular, if images are read in using epsbox.sty in a dvi file with a magnification other than 1000, specify "-gsize:".
If epsbox.sty is used, the PostScript specials having the scale conversion for the magnification are created. This can prevent the loss of the correct size by the two scale conversions of this conversion and the scale conversion in dviout.
