This means you can concatenate multiple +copies (tile, as with \fBpnmtile\fP) to make a continuous larger image. +.PP +\fIcolor\fP is as described for +the +.UR libnetpbm_image.html#colorname +argument of the \fBpnm_parsecolor()\fP library routine +.UE +\&. + + +.UN options +.SH OPTIONS +.PP +All options can be abbreviated to their shortest unique prefix. +You may use two hyphens instead of one to designate an option. You +may use either white space or equals signs between an option name and +its value. + + +.TP +\fB-width \fP\fInumber\fP +The width in pixels of the output image. +.sp +Default is 600. + +.TP +\fB-height \fP\fInumber\fP +The height in pixels of the output image. +.sp +Default is 8. + +.TP +\fB-norepeat\fP + +This option makes \fBppmrainbow\fP end the rainbow with the last +color you specify. Without this option, \fBppmrainbow\fP adds the +first color you specify to the right end of the rainbow as if you had +repeated it. + +.TP +\fB-tmpdir\fP +The directory specification of the directory \fBppmrainbow\fP is +to use for temporary files. +.sp +Default is the value of the \fBTMPDIR\fP environment variable, or +\fB/tmp\fP if \fBTMPDIR\fP is not set. +.sp +\fBppmrainbow\fP always creates a directory within this directory +and creates all its files within that directory. + +.TP +\fB-verbose\fP +Print the "commands" (invocations of other Netpbm +programs) that \fBppmrainbow\fP uses to create the image. + + + +.UN seealso +.SH SEE ALSO +.BR "pgmramp" (1)\c +\&, +.BR "pamseq" (1)\c +\&, +.BR "pamgradient" (1)\c +\&, +.BR "ppmmake" (1)\c +\&, +.BR "ppmfade" (1)\c +\&, +.BR "ppm" (1)\c +\&. + +.UN author +.SH AUTHOR +.PP +Arjen Bax wrote \fBppmrainbow\fP in June 2001 and contributed it +to the Netpbm package.
