NAME 🖥️ ppmtoyuvsplit 🖥️

convert a PPM image to 3 subsampled raw YUV files

SYNOPSIS

ppmtoyuvsplit basename [ppmfile]

DESCRIPTION

This program is part of Netpbm(1) .

ppmtoyuvsplit reads a PPM image as input. Produces 3 raw files basename.Y, basename.U and basename.V as output.

The output files are the subsampled raw YUV representation of the input PPM image, as required by the Stanford MPEG codec. The Y output file contains a byte for each pixel in the image, with the rows going from top to bottom and the columns within each row going left to right. The U and V output files are arranged similarly, except that each byte represents a square of 4 pixels of the image. The value is the arithmetic mean of the value for each of those 4 pixels. Hence, the Y file is 4 times the size of the U file or V file.

The YUV values are scaled according to CCIR.601, as assumed by MPEG.

OPTIONS

There are no command line options defined specifically for ppmtoyuvsplit, but it recognizes the options common to all programs based on libnetpbm (See Common Options .)
