However, the range of colors +(as specified by their RGB values) on a computer does not match the +range of colors that can be represented using the NTSC (or PAL) +systems. If an image with "illegal" colors is sent directly +to an NTSC (or PAL) video system for recording, the +"illegal" colors will be clipped. This may result in an +undesirable looking picture. +.PP +This utility tests each pixel in an image to see if it falls +within the legal NTSC (or PAL) range. If not, it raises or lowers the +pixel's saturation in the output so that it does fall within legal +limits. Pixels that are already OK just go unmodified into the +output. +.PP +Input is from the file named \fIinput\fP. If \fIinput\fP is +\fB-\fP, input is from Standard Input. If you don't specify +\fIinput\fP, input is from Standard Input. +.PP +Output is always to Standard Output. +.PP +This program handles multi-image PPM input, producing multi-image +PPM output. + +.UN options +.SH OPTIONS +.PP +In addition to the options common to all programs based on libnetpbm +(most notably \fB-quiet\fP, see +.UR index.html#commonoptions + Common Options +.UE +\&), \fBppmntsc\fP recognizes the following +command line options: + + + +.TP +\fB--pal\fP +Use the PAL transform instead of the default NTSC. + +.TP +\fB--verbose\fP +Print a grand total of the number of illegal pixels. + +.TP +\fB--debug\fP +Produce a humongous listing of illegal colors and their legal counterparts. +NOTE: This option may produce a great deal of output. + +.TP +\fB--legalonly\fP +Output only pixels that are already legal.
