NAME¶
pbmtoascii - convert a portable bitmap into ASCII graphics
SYNOPSIS¶
pbmtoascii [
-1x2|
-2x4] [
pbmfile]
DESCRIPTION¶
Reads a portable bitmap as input. Produces a somewhat crude ASCII graphic as
output.
Note that there is no asciitopbm tool - this transformation is one-way.
OPTIONS¶
The
-1x2 and
-2x4 flags give you two alternate ways for the bits
to get mapped to characters. With
1x2, the default, each character
represents a group of 1 bit across by 2 bits down. With
-2x4, each
character represents 2 bits across by 4 bits down. With the 1x2 mode you can
see the individual bits, so it's useful for previewing small bitmaps on a
non-graphics terminal. The 2x4 mode lets you display larger bitmaps on a
standard 80-column display, but it obscures bit-level details. 2x4 mode is
also good for displaying graymaps - "pnmscale -width 158 | pgmnorm |
pgmtopbm -thresh" should give good results.
