NAME
pamseq - generate PAM image of all possible tuple values, in sequenceSYNOPSIS
pamseq [ -tupletype=tupletype] depth maxval 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 an equals sign between an option name and its value.DESCRIPTION
This program is part of Netpbm(1). pamseq generates a PAM image of a specified depth and specified maxval that consists of a single row. The row consists of one tuple of every possible value, in order. For a depth of one, the order is simple: From 0 to maxval, going from left to right. For higher depths, the highest numbered plane goes from 0 to maxval (going left to right) while all the other planes have value 0. Then the sequence repeats except with the next highest plane set to a value of 1, then 2, etc.OPTIONS
In addition to the options common to all programs based on libnetpbm (most notably -quiet, seeCommon Options ), pamseq recognizes the following command line option:
- -tupletype
- This is the value of the "tuple_type" attribute of the created PAM image. It can be any string up to 255 characters.
USAGE
To create a simple ramp of the values 0..255, for input to various matrix calculations, trypamseq 1 255(Before pamseq existed, pgmramp was often pressed into service for this). To create a PPM color map of all the possible colors representable with a maxval of 5, do
pamseq 3 5 -tupletype=RGB | pamtopnm
