+\f[V]zint\f[R] - Encode data as a barcode image

+\f[V]zint\f[R] [\f[V]-h\f[R] | \f[V]--help\f[R]]
+.PD 0
+.P
+.PD
+\f[V]zint\f[R] [\f[I]options\f[R]]
+.SH DESCRIPTION
+.PP
+zint takes input data from the command line or a file to encode in a
+barcode which is then output to an image file.
+.PP
+The output image file (specified with \f[V]-o\f[R] or
+\f[V]--output\f[R]) may be in one of these formats: Windows Bitmap
+(\f[V]BMP\f[R]), Enhanced Metafile Format (\f[V]EMF\f[R]), Encapsulated
+PostScript (\f[V]EPS\f[R]), Graphics Interchange Format (\f[V]GIF\f[R]),
+ZSoft Paintbrush (\f[V]PCX\f[R]), Portable Network Format
+(\f[V]PNG\f[R]), Scalable Vector Graphic (\f[V]SVG\f[R]), or Tagged
+Image File Format (\f[V]TIF\f[R]).
+.SH OPTIONS
+.TP
+\f[V]-h\f[R], \f[V]--help\f[R]
+Print usage information summarizing command line options.
+.TP
+\f[V]-b TYPE\f[R], \f[V]--barcode=TYPE\f[R]
+Set the barcode symbology that will be used to encode the data.
+\f[I]TYPE\f[R] is the number or name of the barcode symbology.
+If not given, the symbology defaults to 20 (Code 128).
+To see what types are available, use the \f[V]-t\f[R] or
+\f[V]--types\f[R] option.
+Type names are case-insensitive, and non-alphanumerics are ignored.
+.TP
+\f[V]--addongap=INTEGER\f[R]
+For UPC/EAN symbologies, set the gap between the main data and the
+add-on.
+\f[I]INTEGER\f[R] is in integral multiples of the X-dimension.
+The maximum gap that can be set is 12.
+The minimum is 7, except for UPC-A, when the minimum is 9.
+.TP
+\f[V]--batch\f[R]
+Treat each line of an input file specified with \f[V]-i\f[R] or
+\f[V]--input\f[R] as a separate data set and produce a barcode image for
+each one.
+The barcode images are outputted by default to numbered filenames
+starting with \[lq]00001.png\[rq], \[lq]00002.png\[rq] etc., which can
+be changed by using the \f[V]-o\f[R] or \f[V]--output\f[R] option.
+.TP
+\f[V]--bg=COLOUR\f[R]
+Specify a background (paper) colour where \f[I]COLOUR\f[R] is in hex
+RRGGBB or RRGGGAA format.
+.TP
+\f[V]--binary\f[R]
+Treat input data as raw 8-bit binary data instead of the default UTF-8.
+Automatic code page translation to an ECI page is disabled, and no
+validation of the data\[cq]s encodation takes place.
+.TP
+\f[V]--bind\f[R]
+Add horizontal boundary bars, aka bearer bars, to the symbol.
+The width of the boundary bars must be specified by the
+\f[V]--border\f[R] option.
+\f[V]--bind\f[R] can also be used to add row separator bars to symbols
+stacked with multiple \f[V]-d\f[R] or \f[V]--data\f[R] inputs, in which
+case the width of the separator bars must be specified with the
+\f[V]--separator\f[R] option.
+.TP
+\f[V]--bold\f[R]
+Use bold text for the Human Readable Text.
+.TP
+\f[V]--border=INTEGER\f[R]
+Set the width of boundary bars (\f[V]--bind\f[R]) or box borders
+(\f[V]--box\f[R]), where \f[I]INTEGER\f[R] is in integral multiples of
+the X-dimension.
+.TP
+\f[V]--box\f[R]
+Add a box around the symbol.
+The width of the borders must be specified by the \f[V]--border\f[R]
+option.
+.TP

+any).
+.TP
+\f[V]-d\f[R], \f[V]--data=DATA\f[R]
+Specify the input \f[I]DATA\f[R] to encode.
