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.

ppmtoppm – copy PPM image Synopsisppmtoppm DescriptionThis program is part of Netpbm(1) ppmtoppm simply copies a PPM image from Standard Input to Standard Output. This may seem an unnecessary duplication of cat, but remember that a PPM program can read a PBM or PGM image, and the right kind of PAM, as if it were…
ppmtopjxl – convert a PPM image to an HP PaintJet XL PCL file Synopsisppmtopjxl [-nopack] [-gamma n] [-presentation] [-dark] [-diffuse] [-cluster] [-dither] [-xshift s] [-yshift s] [-xshift s] [-yshift s] [{-xsize|-width|-xscale} s] [{-ysize|-height|-yscale} s] [ppmfile] DescriptionThis program is part of Netpbm(1) ppmtopjxl reads a PPM image as input and produces a PCL file suitable for…
ppmtopj – convert a portable pixmap to an HP PaintJet file Synopsisppmtopj [-gamma val] [-xpos val] [-ypos val] [-back dark|lite] [-rle] [-center] [-render none|snap|bw|dither|diffuse|monodither|monodiffuse|clusterdither|monoclusterdither] [ppmfile] DescriptionReads a portable pixmap as input and converts it into a format suitable to be printed by an HP PaintJet printer. For best results, the input file should be in…
ppmtopict – convert a portable pixmap into a Macintosh PICT file Synopsisppmtopict [ppmfile] DescriptionReads a portable pixmap as input. Produces a Macintosh PICT file as output. The generated file is only the data fork of a picture. You will need a program such as mcvert to generate a Macbinary or a BinHex file that contains…
ppmtopi1 – convert a portable pixmap into an Atari Degas .pi1 file Synopsisppmtopi1 [ppmfile] DescriptionReads a portable pixmap as input. Produces an Atari Degas .pi1 file as output. See Alsopi1toppm(1), ppm(5), pbmtopi3(1), pi3topbm(1) AuthorCopyright (C) 1991 by Steve Belczyk (seb3 [at] gte.com) and Jef Poskanzer.
ppmtopgm – convert a portable pixmap into a portable graymap Synopsisppmtopgm [ppmfile] DescriptionReads a portable pixmap as input. Produces a portable graymap as output. The output is a "black and white" rendering of the original image, as in a black and white photograph. The quantization formula used is .299 r + .587 g + .114…
ppmtopcx – convert a portable pixmap into a PCX file Synopsisppmtopcx [-24bit] [-packed] [-xpos=cols] [-ypos=rows] [ppmfile] DescriptionReads a PPM image as input. Produces a PCX file as output. The type of the PCX file depends on the number of colors in the pixmap: 16 colors or less: 1 bit/pixel, 1-4 planes. 256 colors or less:…
ppmtoneo – convert a portable pixmap into an Atari Neochrome .neo file Synopsisppmtoneo [ppmfile] DescriptionReads a portable pixmap as input. Produces an Atari Neochrome .neo file as output. See Alsoneotoppm(1), ppm(5) AuthorCopyright (C) 2001 by Teemu Hukkanen <tjhukkan [at] iki.fi>, based on ppmtopi1 by Steve Belczyk (seb3 [at] gte.com) and Jef Poskanzer.
ppmtompeg – encodes MPEG-1 bitstreams Synopsisppmtompeg [ options ] parameter-file Descriptionppmtompeg produces an MPEG-1 video stream. param_file is a parameter file which includes a list of input files and other parameters. The file is described in detail below. The -gop, -combine_gops, -frames, and -combine_frames options are all exclusive. This man page is probably incomplete. For…
ppmtomitsu – convert a portable pixmap to a Mitsubishi S340-10 file Synopsisppmtomitsu [-sharpness val] [-enlarge val] [-media string] [-copy val] [-dpi300] [-tiny] [ppmfile] DescriptionReads a portable pixmap as input and converts it into a format suitable to be printed by a Mitsubishi S340-10 printer, or any other Mitsubishi color sublimation printer. The Mitsubishi S340-10 Color…
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…
ppmtolss16 — Convert a PPM to an LSS16 image Synopsisppmtolss16 [ #rrggbb=i …] [< input.ppm] [> output.rle] DescriptionThis manual page documents briefly the ppmtolss16 command. The ppmtolss16 program converts a "raw" PPM file with max 16 colors to a simple RLE-based format: simple RLE-based format unint32 0x1413f3dmagic (littleendian) unint16 xsizelittleendian unint15 ysizelittleendian 16…
