Syntax:
set terminal emf {color | monochrome} {enhanced {noproportional}} {rounded | butt} {linewidth <LW>} {dashlength <DL>} {size XX,YY} {background <rgb_color>} {font "<fontname>{,<fontsize>}"} {fontscale <scale>}
In monochrome mode successive line types cycle through dash patterns. linewidth 4#4factor5#5 multiplies all line widths by this factor. dashlength 4#4factor5#5 is useful for thick lines. 4#4fontname5#5 is the name of a font; and 4#4fontsize5#5 is the size of the font in points.
The nominal size of the output image defaults to 1024x768 in arbitrary units. You may specify a different nominal size using the size option.
Enhanced text mode tries to approximate proportional character spacing. If you are using a monospaced font, or don't like the approximation, you can turn off this correction using the noproportional option.
The default settings are color font "Arial,12" size 1024,768 Selecting default sets all options to their default values.
Examples:
set terminal emf 'Times Roman Italic, 12'
