 \fIdpiValue\fR is used in conversion between given coordinates and
 screen resolution. The value must be greater than 0 and the default
 value is 96.
 \fIscaleValue\fR is used to scale the resulting image. The value must
 be greater than 0 and the default value is 1.
-\fIunitValue\fR is the unit of all coordinates in the SVG data.
