 \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.
-Available units are px (default, coordinates in pixel), pt (1/72 inch),
-pc (12 pt), mm , cm and in.
+\fIwidth\fR and \fIheight\fR are the width or height that the image

+\fB\-scaletowidth\fR and \fB\-scaletoheight\fR can be given at a time
