pamdeinterlace(1)		     General Commands Manual			pamdeinterlace(1)

NAME
       pamdeinterlace - remove ever other row from a PAM/PNM image

SYNOPSIS
       pamdeinterlace [-takeodd] [-takeeven] N [infile]

       You  can  use  the  minimum  unique  abbreviation of the options.  You can use two hyphens
       instead of one.	You can separate an option name from its value with white  space  instead
       of an equals sign.

DESCRIPTION
       pamdeinterlace  Removes	all  the even-numbered or odd-numbered rows from the input PNM or
       PAM image.  Specify which with the -takeeven and -takeodd options.

       This can be useful if the image is a video capture from an interlaced  video  source.   In
       that  case,  each row shows the subject 1/60 second before or after the two rows that sur-
       round it.  If the subject is moving, this can detract from the quality of the image.

       Because the resulting image is half the height of the input image, you will then  want  to
       use pamstretch or pnmscale to restore it to its normal height:

       pamdeinterlace myimage.ppm | pamstretch -yscale=2 >newimage.ppm

OPTIONS
       -takeodd
	      Take the odd-numbered rows from the input and put them in the output.  The rows are
	      numbered starting at zero, so the first row in the output is the	second	row  from
	      the input.  You cannot specify both -takeeven and -takeodd.

       -takeeven
	      Take  the  even-numbered	rows from the input and put them in the output.  The rows
	      are numbered starting at zero, so the first row in the output is the first row from
	      the input.  This is the default.	You cannot specify both -takeeven and -takeodd.
