+Add paddings to the input image, and place the original input at the

+
+It accepts the following options:
+
+@table @option
+@item width, w
+@item height, h
+Specify an expression for the size of the output image with the
+paddings added. If the value for @var{width} or @var{height} is 0, the
+corresponding input size is used for the output.
+
+The @var{width} expression can reference the value set by the

+The default value of @var{width} and @var{height} is 0.

+
+The default value of @var{x} and @var{y} is 0.

+If @var{x} or @var{y} evaluate to a negative number, they'll be changed
