The Linux Manuals (man pages) document is an important part of Linux documents. Linux Manuals are organized as several sections. Each section has a group of commands for a specific area in Linux usage, administration or development.
ppmtomap – extract all colors from a portable pixmap DescriptionThis program exists only for backward compatibility. Use pnmcolormap, which replaced it in January 2002. One trivial difference between ppmtomap and pnmcolormap all is that if the input is PBM or PGM, ppmtomap would produce PPM output, whereas pnmcolormap all produces the same kind of output…

ppmtoeyuv – convert a portable pixmap into a Berkeley YUV file Synopsisppmtoeyuv [ppmfile] DescriptionReads a portable pixmap as input. Produces a Berkeley Encoder YUV (not the same as Abekas YUV) file on the Standard Output file. With no argument, takes input from Standard Input. Otherwise, ppmfile is the file specification of the input file. ppmtoeyuv…
