X.SH NAME
Xpbmcrop - crop a portable bitmap
X.SH SYNOPSIS
Xpbmcrop [-0] [-1] [pbmfile]
X.SH DESCRIPTION
XReads a portable bitmap as input.
XRemoves edges that are the background color,
Xand produces a portable bitmap as output.
XBy default, it makes a guess as to what the background
Xcolor is.
XYou can override the default with the -0 and -1 flags.

X.SH NAME
Xpbmtrnspos - transpose a portable bitmap x for y
X.SH SYNOPSIS
Xpbmtrnspos [pbmfile]
X.SH DESCRIPTION
XReads a portable bitmap as input.
XTransposes it x for y and produces a portable bitmap as output.
X.PP
XNote that transposition is not rotation, but can be used to produce it.
XFor example, if you wanted a 90 degree clockwise rotation, perhaps for
Xprinting a landscape bitmap on a laser printer, you could
Xdo 'pbmtrnspos | pbmfliplr' or 'pbmfliptb | pbmtrnspos'.
XFor counter-clockwise rotation, you would use the opposite flips.

X.SH NAME
Xpbmpaste - paste a rectangle into a portable bitmap
X.SH SYNOPSIS
Xpbmpaste frompbmfile x y [intopbmfile]
X.SH DESCRIPTION
XReads two portable bitmaps as input.
XInserts the first bitmap into the second at the specified location,
Xand produces a portable bitmap as output.
X.PP
XThis is most useful in combination with pbmcut(1).
XFor instance, if you want to edit a small segment of a large
Xbitmap, and your bitmap editor is TOO STUPID to edit the
Xlarge bitmap, you can cut out the segment you are interested in,
Xedit it, and then paste it back in.

Xxxxtopbm - convert "xxx" bitmaps into portable bitmaps
X.SH SYNOPSIS
Xxxxtopbm [xxxfile]
X.SH DESCRIPTION
XReads an "xxx" bitmap as input.
XProduces a portable bitmap as output.
X.LP
X"xxx" bitmaps are the unknown and undocumented format found on
Xucbvax.Berkeley.Edu in the directory pub/xbackgrounds.
XThe arrangement of the bits is the same as for Sun rasterfiles, but
Xthe headers are completely different.

X.TH pbm 5 "18 February 1988"
X.SH NAME
Xpbm - portable bitmap file format
X.SH DESCRIPTION
XThe portable bitmap format is a lowest common denominator.
XIt was originally designed to make it reasonable to mail bitmaps
Xbetween different types of machines using the typical stupid network
Xmailers we have today.
XNow it serves as the common language of a large family of bitmap
Xconversion filters.
XThe definition is as follows:
X.IP - 2
XA width, formatted as ASCII characters in decimal.
X.IP - 2
XWhitespace (blanks, TABs, CRs, LFs).
X.IP - 2
XA height, again in ASCII decimal.
X.IP - 2
XWhitespace.
X.IP - 2
XWidth * height bits, each either '1' or '0', starting at the top-left
Xcorner of the bitmap, proceding in normal English reading order.
X.IP - 2
XThe character '1' means black, '0' means white.
X.IP - 2
XWhitespace in the bits section is ignored.
X.IP - 2
XCharacters from a "#" to the next end-of-line are ignored (comments).
X.IP - 2
XNo line may be longer than 70 characters.
X.PP
XHere is an example of a small bitmap in this format:
X.PP
X.nf
X# feep.pbm
X24 7
X0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
X0 1 1 1 1 0 0 1 1 1 1 0 0 1 1 1 1 0 0 1 1 1 1 0
X0 1 0 0 0 0 0 1 0 0 0 0 0 1 0 0 0 0 0 1 0 0 1 0
X0 1 1 1 0 0 0 1 1 1 0 0 0 1 1 1 0 0 0 1 1 1 1 0
X0 1 0 0 0 0 0 1 0 0 0 0 0 1 0 0 0 0 0 1 0 0 0 0
X0 1 0 0 0 0 0 1 1 1 1 0 0 1 1 1 1 0 0 1 0 0 0 0
X0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
X.fi
X.PP
XPrograms that read this format should be as lenient as possible,
Xaccepting anything that looks remotely like a bitmap.
XFor instance, the above example does not actually conform to the
Xstandard, since it has whitespace before the width; neverthless,
Xit should be accepted.
