For example, separating 33\fBlenna.ppm\fP would result in \fBlenna.red\fP, \fBlenna.grn\fP, 34and \fBlenna.blu\fP. If the input comes from stdin, the names are 35\fBnoname.red\fP, \fBnoname.grn\fP, and \fBnoname.blu\fP. 36 37.UN lbAE 38.SH SEE ALSO 39.BR "rgb3toppm" (1)\c 40\&, 41.BR "pamchannel" (1)\c 42\&, 43.BR "ppmtopgm" (1)\c 44\&, 45.BR "pgmtoppm" (1)\c 46\&, 47.BR "ppm" (5)\c 48\&, 49.BR "pgm" (5)\c 50\& 51 52 53.UN lbAF 54.SH AUTHOR 55 56Copyright (C) 1991 by Jef Poskanzer. 57.SH DOCUMENT SOURCE 58This manual page was generated by the Netpbm tool 'makeman' from HTML 59source.
