If <TT>fontnames</TT> is undefined or <TT>"svg"</TT>,

the output will try to use known SVG fontnames. For example, the
719
default font <TT>"Times-Roman"</TT> will be mapped to the
720
basic SVG font <TT>"serif"</TT>. This can be overridden by setting
721
<TT>fontnames</TT> to <TT>"ps"</TT> or <TT>"gd"</TT>.
722
In the former case, known PostScript font names such as
723
<TT>"Times-Roman"</TT> will be used in the output.
724
In the latter case, the fontconfig font conventions
725
are used. Thus, <TT>"Times-Roman"</TT> would be treated as
726
<TT>"Nimbus Roman No9 L"</TT>. These last two options are useful

If, however, <TT>fixedsize=true</TT>,
814
the width and height attributes specify the exact size of the node.

During rendering, in the default case (<TT>imagescale=false</TT>),
817
the image retains its natural size.
818
If <TT>imagescale=true</TT>,
819
the image is uniformly scaled (i.e., its aspect ration is
820
preserved) to fit inside the node.
821
At least one dimension of the image will be as large as possible

823
When <TT>imagescale=width</TT>,

the width of the image is scaled to fill the node width.

The corresponding property holds when <TT>imagescale=height</TT>.
826
When <TT>imagescale=both</TT>,
827
both the height and the width are scaled separately to fill the node.

In all cases, if a dimension of the image is larger than the

corresponding dimension of the node, that dimension of the

image is scaled down to fit the node. As with the case of

966
Note that the margin is not part of the drawing but just empty space
967
left around the drawing. It basically corresponds to a translation of
968
drawing, as would be necessary to center a drawing on a page. Nothing
969
is actually drawn in the margin. To actually extend the background of

a drawing, see the <A HREF=#d:pad>pad</A> attribute.

For nodes, this attribute specifies space left around the node's label.

1144
<DD> The pad attribute specifies how much, in inches, to extend the

drawing area around the minimal area needed to draw the graph.
1146
If the pad is a single double, both the x and y pad values are set
1147
equal to the given value. This area is part of the
1148
drawing and will be filled with the background color, if appropriate.
1150
Normally, a small pad is used for aesthetic reasons, especially when
1151
a background color is used, to avoid having nodes and edges abutting
1152
the boundary of the drawn region.

At present, this only works for PostScript output. For other types of

1198
For nodes, the position indicates the center of the node.
1038
In neato and fdp, pos can be used to set initial position of a node.
1039
Concerning this, see the <A HREF=command.html#d:s>-s</A> command line flag.
1199
On output, the coordinates are in <A HREF=#points>points</A>.
1201
In neato and fdp, pos can be used to set the initial position of a node.
1202
By default, the coordinates are assumed to be in inches. However, the

1206
When the <A HREF=command.html#d:n>-n</A> command line flag is used with
1207
neato, it is assumed the positions have been set by one of the layout
1208
programs, and are therefore in points. Thus, <TT>neato -n</TT> can accept
1209
input correctly without requiring a <TT>-s</TT> flag and, in fact,

ignores any such flag.
