.SH NAME
makepattern \- make GMT color pattern from b/w pattern or icon
.SH SYNOPSIS
\fBmakepattern\fP \fI1bit.ras\fP | \fIiconfile\fP \fB\-Cf\fP\fIr/g/b\fP \fB\-Cb\fP\fIr/g/b\fP
.SH DESCRIPTION
\fBmakepattern\fP reads either a Sun 1-bit rasterfile OR a Sun icon file.  It then accepts color choices for the foreground and
background pixels and colorizes the pattern, writing it as a 8-bit Sun rasterfile on stdout.
These patterns may then be used in \fBGMT\fP (3.1 or later) \fB\-Gp\fP settings or by \fBpsimage\fP.
.TP
\fI1bit.ras\fP | \fIiconfile\fP
Either a 1-bit Sun rasterfile (standard format, no RLE) or a Sun icon file (as used in \fBGMT\fP 3.0).
.TP
\fB\-Cf\fP
Sets the color for the foreground pixels (the ones) [black].
.TP
\fB\-Cb\fP
Sets the color for the background pixels (the zeros) [white].
.SH WIN32 fix
Since binary redirection under WIN32 does not work, you must specify the
output file with \fB\-G\fP\fInewfile.ras\fP.  This option is only available
under WIN32.
.SH EXAMPLES
.sp
To create a colorized red/blue 8-bit Sun rasterfile pattern from the old 3.0-style iconpattern
stored in file custom.icon, run
.sp
\fBmakepattern\fP custom.icon \fB\-Cf\fPred \fB\-Cb\fPblue > custom.ras
.sp
To create a green/blue 8-bit Sun rasterfile pattern from a 1-bit Sun raster called bits.ras, run
.sp
\fBmakepattern\fP bits.ras \fB\-Cf\fPgreen \fB\-Cb\fPblue > colorbits.ras
