* A set-OCG-state action (PDF 1.5) sets the state of one or more optional content
|
||||
* groups.
|
||||
* @param state an array consisting of any number of sequences beginning with a <CODE>PdfName</CODE>
|
||||
* or <CODE>String</CODE> (ON, OFF, or Toggle) followed by one or more optional content group dictionaries
|
||||
* <CODE>PdfLayer</CODE> or a <CODE>PdfIndirectReference</CODE> to a <CODE>PdfLayer</CODE>.<br>
|
||||
* The array elements are processed from left to right; each name is applied
|
||||
* to the subsequent groups until the next name is encountered:
|
||||
* <ul>
|
||||
* <li>ON sets the state of subsequent groups to ON</li>
|
||||
* <li>OFF sets the state of subsequent groups to OFF</li>
|
||||
* <li>Toggle reverses the state of subsequent groups</li>
|
||||
* </ul>
|
||||
* @param preserveRB if <CODE>true</CODE>, indicates that radio-button state relationships between optional
|
||||
* content groups (as specified by the RBGroups entry in the current configuration
|
||||
* dictionary) should be preserved when the states in the
|
||||
* <CODE>state</CODE> array are applied. That is, if a group is set to ON (either by ON or Toggle) during
|
||||
* processing of the <CODE>state</CODE> array, any other groups belong to the same radio-button
|
||||
* group are turned OFF. If a group is set to OFF, there is no effect on other groups.<br>
|
||||
* If <CODE>false</CODE>, radio-button state relationships, if any, are ignored
|
