ppmgrad(1) AMIGA (5 April 1994) ppmgrad(1)
NAME
ppmgrad - blends one or more colors along a vertical scale.
SYNOPSIS
ppmgrad [-sin] width height color1 ... [color10]
DESCRIPTION
Produces a portable pixmap of the specified width, height,
with a gradient blending one color into the next. A maximum
of ten colors can be specified. By default, blending is
done along a linear ramp. The -sin option blends colors
along a sinusoidal ramp.
The colors can be specified in five ways:
o A name, assuming that a pointer to an X11-style color
names file was compiled in.
o An X11-style hexadecimal specifier: rgb:r/g/b, where r
g and b are each 1- to 4-digit hexadecimal numbers.
o An X11-style decimal specifier: rgbi:r/g/b, where r g
and b are floating point numbers between 0 and 1.
o For backwards compatibility, an old-X11-style
hexadecimal number: #rgb, #rrggbb, #rrrgggbbb, or
#rrrrggggbbbb.
o For backwards compatibility, a triplet of numbers
separated by commas: r,g,b, where r g and b are
floating point numbers between 0 and 1. (This style
was added before MIT came up with the similar rgbi
style.)
