# -BMP:

"-BMP:" is the option specified on the command line or in the parameter file. The setting is made in the [Display] of Property Sheets.
When "-BMP:<x>:<y>:<z>" is set, the gray scale display is compressed by 1/<x> in the horizontal direction and 1/<y> in the vertical direction. The <z>/1000 performs gamma correction.
If -<z> is set instead of <z>, the screen is displayed in reverse the black/white.
If ":<z>" is omitted, the interpretation is "<z>=800". If ":<y>:<z>" is omitted, the interpretation is <y>=<x>. The default is
-BMP: 4:4:800
