You may separate an option +name and its value with white space instead of an equals sign. + +.UN description +.SH DESCRIPTION +.PP +This program is part of +.BR "Netpbm" (1)\c +\&. +.PP +This program tries to produce an accurate representation of a PPM +image on an terminal that implements the ANSI ISO 6429 standard. It +approximates colors, finding the minimum Cartesian distance between the +input RGB vectors and the ones in the generated palette. As the +available color palette is somewhat restricted, you get the best +results when the colors in the original image are few and the RGB +intensities are close to zero, half of maximum, and maximum. +.PP +You can usually get good results with cartoons or images with +plain colors (no gradients). With photos, results can vary, but are +usually not very accurate. +.PP +The output image has one line for each row and one character for each +column of the input image. E.g. an 80 pixel by 25 pixel PPM image would +fill up an 80x25 terminal screen. Use \fBpamscale\fP or \fBpamcut\fP +to make your image fit properly on your screen. +.PP +Furthermore, use \fBpamscale\fP to recover the proper aspect ratio, +because a character on a terminal screen is rarely square. Typically, a +character is twice has high as it is wide, so in order for a 20x20 image to +appear square on your terminal, as it should, you'll want to squash it +vertically or stretch it horizontally by a factor of two (resulting int 10x20 +characters are 20x40 characters). +.PP +The image starts at the current cursor position on the terminal +screen. Each successive row starts at Column 0 on the screen. If you want +to shift the image up or down, for example to center it, use +\fBpnmpad\fP on the input. +.PP +This program was born with the objective of displaying nice color +images on the Linux console, e.g. a proper logo at Linux boot. +.PP +\fBppmtoascii\fP does a similar things, but combines 2 or 8 pixels into +one character, where the character roughly represents those particular pixels, +whereas \fBppmtoterm\fP displays each character of the image as a single +pixel. +.PP +\fBpbmto4425\fP does a similar thing for black and white images, using +line drawing characters, on some terminals. + +.UN options +.SH OPTIONS +.PP +There are no command line options defined specifically +for \fBppmtoterm\fP, but it recognizes the options common to all +programs based on libnetpbm (See +.UR index.html#commonoptions + Common Options +.UE +\&.) + +.UN seealso +.SH SEE ALSO +.BR "pamscale" (1)\c +\&, +.BR "pamcut" (1)\c +\&, +.BR "ppmtoascii" (1)\c +\&, +.BR "pbmtoascii" (1)\c +\&, +.BR "pbmto4425" (1)\c +\&, +.BR "ppm" (1)\c +\& + + +.UN author +.SH AUTHOR + +Copyright (C) 2002 by Ero Carrera. + + +.UN history +.SH HISTORY +.PP +This program was new in Netpbm 10.9 (August 2002). +.SH DOCUMENT SOURCE +This manual page was generated by the Netpbm tool 'makeman' from HTML +source.
