<P STYLE="font-style: normal">The amount of whitespace to the left

switch. For example:</P>
<P STYLE="font-style: normal"><FONT FACE="Courier, monospace"><FONT SIZE=2>zint

Adding boundary bars and boxes</B></FONT></P>
<P STYLE="font-style: normal">Zint allows the symbol to be bound with
'boundary bars' using the option --bind. These bars help to prevent
misreading of the symbol by corrupting a scan if the scanning beam
strays off the top or bottom of the symbol. Zint can also put a
border right around the symbol and its whitespace with the --box
option. This option is automatically chosen for ITF-14 symbols.</P>
<P STYLE="font-style: normal">The width of the boundary or box can be
specified using the --border switch. For example:</P>
<P STYLE="font-style: normal"><FONT FACE="Courier, monospace"><FONT SIZE=2>zint
--box --border=10 -d 'This'</FONT></FONT></P>
<P STYLE="font-style: normal">gives a box with a width 10 times the

Using colour</B></FONT></P>
<P STYLE="font-style: normal">The default colours of a symbol are a
black symbol on a white background. Zint allows you to change this.
The -r switch allows the default colours to be inverted so that a
white symbol is shown on a black background. For example the command</P>
<P STYLE="font-style: normal"><FONT FACE="Courier, monospace"><FONT SIZE=2>zint
-r -d 'This'</FONT></FONT></P>
<P STYLE="font-style: normal">gives an inverted Code 128 symbol. This

and background colours can be specified using the <FONT FACE="Courier, monospace">--fg=</FONT>

For example the command
