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.

OptionsAll option names may be abbreviated; for example, –optimize may be written –optim or –opt. For…
pnmtoddif – Convert a portable anymap to DDIF format Syntaxpnmtoddif pnmtoddif [-resolution x y] [pnmfile [ddiffile]] Optionsresolution x y The horizontal and vertical resolution of the output image in dots per inch. Defaults to 78 dpi. pnmfile The filename for the image file in pnm format. If this argument is omitted, input is read from…
pnmtile – replicate a portable anymap into a specified size Synopsispnmtile width height [pnmfile] DescriptionReads a portable anymap as input. Replicates it until it is the specified size, and produces a portable anymap as output. See Alsopnm(5) AuthorCopyright (C) 1989 by Jef Poskanzer.
pnmstitch – stitch together two panoramic (side-by-side) photographs Synopsispnmstitch [ [left_filespec] right_filespec | left_filespec right_filespec output_filespec ] [-width=width] [-height=height] [-xrightpos=column] [-yrightpos=row] [-stitcher={RotateSliver, BiLinearSliver,LinearSliver}] [-filter={LineAtATime,HorizontalCrop}] [-output=output_filespec] [-verbose] All options can be abbreviated to their shortest unique prefix. You may use two hyphens instead of one. You may separate an option name and its value with white…
pnmsplit – split a multi-image portable anymap into multiple single-image files Synopsispnmsplit [pnmfile[ output_file_pattern]] DescriptionReads a Netpbm file as input. Copies each image in the input into a separate file, in the same format. pnmfile is the file specification of the input file, or – to indicate Standard Input. The default is Standard Input. output_file_pattern…
pnmsmooth – smooth out an image Synopsispnmsmooth [-size width height] [-dump dumpfile] [pnmfile] DescriptionSmooths out an image by replacing each pixel with the average of its width X height neighbors. It is implemented as a C progam that generates a PGM convolution matrix and then invokes pnmconvol. Options-size width height Specifies the size of the…
pnmshear – shear a portable anymap by some angle Synopsispnmshear [-noantialias] angle [pnmfile] DescriptionReads a portable anymap as input. Shears it by the specified angle and produces a portable anymap as output. If the input file is in color, the output will be too, otherwise it will be grayscale. The angle is in degrees (floating…
pnmscalefixed – scale a portable anymap quickly, but less accurate Descriptionpnmscalefixed is the same thing as pnmscale except that it uses fixed point arithmetic internally instead of floating point, which makes it run faster. In turn, it is less accurate and may distort the image. Use the pnmscale man page with pnmscalefixed. This man page…
pnmscale – scale a portable anymap Synopsispnmscale scale_factor [pnmfile] pnmscale -reduce reduction_factor [pnmfile] pnmscale [{-xsize=cols | -width=cols | -xscale=factor}] [{-ysize=rows | -height=rows | -yscale=factor}] [pnmfile] pnmscale -xysize cols rows [pnmfile] pnmscale -pixels n [pnmfile] Miscellaneous options: -verbose -nomix Minimum unique abbreviation of option is acceptable. You may use double hypens instead of single hyphen to…
pnmrotate – rotate a portable anymap by some angle Synopsispnmrotate [-noantialias] angle [pnmfile] DescriptionReads a portable anymap as input. Rotates it by the specified angle and produces a portable anymap as output. If the input file is in color, the output will be too, otherwise it will be grayscale. The angle is in degrees (floating…

pnmquantall – run Pnmquant on a bunch of files all at once, so they share a common colormap Synopsispnmquantall [-ext extension] ncolors netpbm_file… Note that the usual syntax rules for Netpbm programs don’t apply to this program. For example, you can’t abbreviation -ext and you can’t put it anywhere on the line you want. DescriptionThis…
pnmquant – quantize the colors in a Netpbm image to a smaller set Synopsispnmquant [-center|-meancolor|-meanpixel] [-floyd|-fs] [-nofloyd|-nofs] [-spreadbrightness|-spreadluminosity] ncolors [pnmfile] All options can be abbreviated to their shortest unique prefix.
