+.SS BACKGROUND COLOR
+You can use the
+.B --background-color
+option (
+.B -b
+for short) to specify the backgroung color that will appear in parts of the image that would otherwise
+be transparent.  This option accepts the same syntax as the CSS
+.B color
+property, so you can use
+.B #rrggbb
+syntax or CSS named colors like
+.BR white .
