Returns the enum constant of this class with the specified name.
The string must match exactly an identifier used to declare an
enum constant in this class. (Extraneous whitespace characters are
not permitted.)
Parameters:
name - the name of the enum constant to be returned.
Gets the size of the watermark to apply to a media of this resolution. The settings are read
on demand and not once for all at the initialization of this enumeration: the resources of
Silverpeas aren't necessarily available when the class is loaded (this is the case for
example when the class is loaded by a documentation or a code analysis tool).
Returns:
the size of the watermark or null if no watermark is applicable.
