X.SH NAME
Xfbcat \- convert image format
X.SH SYNOPSIS
X.nf
Xfbcat [ -a<aspect> -t'title' -c'credits' ] [ -<type> ] [ image ] > image
X.fi
X.SH DESCRIPTION
X.PP
XA general format converter. It can read any of the known formats
Xand write one of the specified output formats (see fbm(1) for format
Xdetails). Note that some conversions require more than simple format
Xchanges, such as color to grayscale or grayscale to 1bit. For these
Xconversion you must use a pipeline of ther commands.
X.SH OPTIONS
X.TP
X.BR -a<aspect>
X.I aspect ratio,
Xa floating point number which is the ratio of the height of a pixel to
Xits width. Some formats specify this, and for GIF images the reader
Xattempts to guess from the size of the image. This option overrides
Xthe input or guessed aspect ratio. So if you know that your GIF image
Xhas a 1-1 aspect ratio, you should specify -a1 to override the guess.
X.TP
X.BR -t'title'
X.I title,
Xspecify a character string (up to 80 characters) to describe the image.
XThe default is no title.
X.TP
X.BR -c'credits'
X.I credits or subtitle,
Xspecify a second character string (up to 80 characters) to describe the
Ximage. The default is no credit string.
X.TP
X.BR -B
X.I face
Xformat, as used by Bennet Yee's
X.I face
Xprogram at CMU.
X.TP
X.BR -F
X.I FBM,
Xformat (by default, the default). You are guaranteed not
Xto lose information by specifying FBM as the default.
X.TP
X.BR -G
X.I GIF,
XCompuserve GIF format.
X.TP
X.BR -I
X.I IFF
Xformat, interleaved bitmaps (ILBM), used by Amigas.
X.TP
X.BR -P
X.I PBM,
XJef Poskanzer's bitmap format.
X.TP
X.BR -S
X.I sun,
XSun rasterfiles (not run length encoded).
X.SH EXAMPLE
X.PP
XTo convert a GIF file to an IFF file
X.sp
X % fbcat -I < foo.gif > foo.iff
X.sp
XTo convert a Sun raster file to an FBM file, adding a title:
X.sp
X % fbcat -t'Title String' < bar.8bit > bar.fbm
X.SH SEE ALSO
Xfbm(1) for general discussion, pbm(1) for PBM routines.
X.SH BUGS
XNone known.

X.SH NAME
Xfbext \- extract a rectangle from an image, resize, change aspect ratio
X.SH SYNOPSIS
X.nf
Xfbext [ -w<width> -h<height> -W<maxwdith> -H<maxheight>
X -s<size> -a<aspect> -t'title' -c'credits' ] [ -<type> ]
X [ x y [ width height ] ] < bitmap > bitmap
X.fi
X.SH DESCRIPTION
X.PP
XExtract a rectangle from a bitmap and resize it. There are lots of
Xarguments, but you'll typically only give it a few. For example, you
Xshould only specify two of width, height and aspect ratio, and it will
Xcalculate the third. The rectangle spec is given as 2 or 4 positional
Xarguments after the flags, and if omitted the entire input image is
Xcopied.
X.sp
XThe maximum width and height override all other size specifications, so
Xthey can be used ot keep the results displayable on your screen.
X.sp
XWhen working with Amiga images, remember that the original input has an
Xaspect ratio of 1.2, so a common operation is "fbext -a1" which expands
Xthe smaller dimension to give an output with an aspect ratio of 1.
X.SH OPTIONS
X.TP
X.B -SPFB
X.I output file format,
XS=sun, P=pbm, F=fbm, B=face format. Only one may be specified.
X.TP
X.B -a
X.I aspect ratio,
Xspecify desired output aspect ratio.
X.TP
X.B -w
X.I width,
Xspecify desired output width in pixels.
X.TP
X.B -h
X.I height,
Xspecify desired output height in pixels.
X.TP
X.B -s
X.I size,
Xspecify desired number of pixels in output (eg: 320x200 is 64000 pixels.
X.TP
X.B -W
X.I maximum width,
Xof output. The image will be expanded up to this size, keeping the
Xspecified aspect ratio.
X.TP
X.B -H
X.I maximum height.,
X.TP
X.BR -t'title'
X.I title,
Xspecify a character string (up to 80 characters) to describe the image.
XThe default is no title.
X.TP
X.BR -c'credits'
X.I credits or subtitle,
Xspecify a second character string (up to 80 characters) to describe the
Ximage. The default is no credit string.
X.PP
X.SH EXAMPLE
X.PP
XSuppose you have a GIF file with 320 by 200 pixels and an aspect ratio
Xof 1.2 (that is, it looks right at 320 by 240 pixels). You want to
Xblow it up to fit your Sun screen (1152 by 900). You want the output
Xratio adjusted to be 1.0 so it will look right on the Sun.
X.sp
Xfbext -S -W1152 -H900 -a1.0 < foo.gif > foo.raster
X.sp
XYou have an FBM format file 512 by 384 and you want to extract a
Xrectangle 300 by 200 from the middle:
X.sp
Xfbext -F 106 92 300 200 < foo.fbm > bar.fbm

X.TH FBQUANT 1 07-Apr-89
X.CM 3
X.SH NAME
Xfbquant \- quantize a 24 bit color image
X.SH SYNOPSIS
X.nf
Xfbquant [ -c<numcolors> ] [ -<type> ] [ -m<map> ] < rgb-image > mapped-image
X.fi
X.SH DESCRIPTION
X.PP
XConverts a 3 plane red-green-blue color image into a
Xmapped color image. Uses Heckbert's adaptive partitioning
Xcolor quantizing algorithm. It is strongly suggested that you make the
Xnumber of colors used a power of 2, but not necessary for proper
Xoperation of FBM.
X.sp
XIf you wish to requantize an image that is already mapped (for example,
Xto reduce the number of colors), use "gray2clr -u" to unmap the image
Xfirst. This unmapping step is also necessary to resize a color image
Xusing fbext(1).
X.sp
XYou may specify a particular color map with the
X.B -m
Xoption. The argument is another mapped color image.
X.sp
XNote that even if you specify fewer than 256 colors, some output
Xformats (SUN and FBM) will still use 8 bits to store each color index.
XThe color map will be the specified length.
X.SH OPTIONS
X.TP
X.BR -c<num>
X.I number of colors
Xto use for dithering. The range is 8 to 256, and the default is 256.
X.TP
X.BR -m<map>
X.I colormap
Xoption, specifies that the colormap from the
X.I map
Ximage is to be used to quantize he input. Colormaps may be efficiently
Xstored by extracting very small rectangles
Xfrom another color image:
X.sp
X % fbext 0 0 1 1 < image.clr > map.clr
X.sp
Xwhich stores a 1 pixel image with the desired map.
X.TP
X.BR -F
X.I FBM,
Xformat (by default, the default). You are guaranteed not
Xto lose information by specifying FBM as the default.
X.TP
X.BR -G
X.I GIF,
XCompuserve GIF format.
X.TP
X.BR -I
X.I IFF
Xformat, interleaved bitmaps (ILBM), used by Amigas.
XIt is recommended that you use 16 or 32 colors, because the EL Arts
Xcode limits IFF files to 6 planes, and most Amiga software cannot
Xhandle more than 32 colors anyway.
X.TP
X.BR -S
X.I sun,
XSun rasterfiles (not run length encoded).
X.SH EXAMPLE
X.PP
XTo convert a 24 bit Sun rasterfile to an 8 bit mapped color rasterfile:
X.sp
X % fbquant -S < foo.24bit > foo.clr
X.sp
XTo convert a 24 bit Sun rasterfile to a 32 color Amiga image:
X.sp
X % fbext -a1.2 -w320 < foo.24bit | \
X.br
X fbquant -I -c32 > foo.iff
X.sp
XTo convert an FBM format RGB color image to a 16 color GIF image:
X % fbext -a1.2 -w320 < foo.24bit | \
X.br
X fbquant -G -c16 > foo.gif
X.SH SEE ALSO

X.CM 3
X.SH NAME
Xfbsample \- convert 1bit image to grayscale by sampling
X.SH SYNOPSIS
X.nf
Xfbsample [ -t'title' -c'credits' -g'grain' -n'nbr']
X [ -<type> ] < bitmap > image
X.fi
X.SH DESCRIPTION
X.PP
XSamples a 1 bit deep pbm file using a square neighborhood of the
Xspecified size, and outputs an 8 bit file. You will want to run
X.I fbnorm
Xon the output to expand the scale to 255, and there will be a small
Xloss of sharpness, so
X.I fbsharp
Xwill also be useful. Once you have an 8 bit file, you can resize it
Xarbitrarily, and then convert it back to a 1 bit file, if need be.
XThe default neighborhood size is 8 by 8, which gives 65 different gray
Xlevels.
X.SH OPTIONS
X.TP
X.B -g
X.I grain
Xsize. The sample is taken every
X.I grain
Xpixels.
X.TP
X.B -n
X.I neighborhood
Xsize. The value will be the number of light pixels in the nearby NxN
Xsquare. The values can range from 1 to 16.
X.TP
X.BR -t'title'
X.I title,
Xspecify a character string (up to 80 characters) to describe the image.
XThe default is no title.
X.TP
X.BR -c'credits'
X.I credits or subtitle,
Xspecify a second character string (up to 80 characters) to describe the
Ximage. The default is no credit string.
X.TP
X.BR -B
X.I face
Xformat, as used by Bennet Yee's
X.I face
Xprogram at CMU.
X.TP
X.BR -F
X.I FBM,
Xformat (by default, the default). You are guaranteed not
Xto lose information by specifying FBM as the default.
X.TP
X.BR -G
X.I GIF,
XCompuserve GIF format.
X.TP
X.BR -I
X.I IFF
Xformat, interleaved bitmaps (ILBM), used by Amigas.
X.TP
X.BR -P
X.I PBM,
XJef Poskanzer's bitmap format.
X.TP
X.BR -S
X.I sun,
XSun rasterfiles (not run length encoded).
X.PP
X.SH EXAMPLE
X.PP
XSuppose you have a 480 by 600 face format file (-B) that you wish to
Xshrink to 300 by 375 and convert to PostScript (say for inclusion
Xin your door label). Here's a pipeline to do that:
X.sp
X.nf
X % fbsample -n5 -g1 < my.face | \ # sample 5x5
X fbnorm -b4 -w1 | # normalize
X fbext -w300 | \ # make 300 pixels wide
X fbhalf -s20 | \ # halftone and really sharpen
X pbm2ps -s 1 > sdoor.ps # convert to postscript
X.fi
X.SH SEE ALSO
Xfbnorm(1) to normalize the output,
Xfbm(1) for general discussion, pbm(1) for PBM routines.
