Examples
Allowed forms of the trailer PI:
xpacket end=“w”?xpacket end=“r”?
Remarks
The end=“w” or end=“r” portion shall be used by packet scanning processors to determine whether the XMPmay be modified in-place.
Constructors
XmpTrailerPi(bool)
Initializes a new instance of the Aspose.Imaging.Xmp.XmpTrailerPi class.
public XmpTrailerPi(bool isWritable)
{
}Parameters
isWritable bool
Inditacates whether trailer is writable.
XmpTrailerPi()
Initializes a new instance of the Aspose.Imaging.Xmp.XmpTrailerPi class.
public XmpTrailerPi()
{
}Properties
IsWritable
Gets or sets a value indicating whether this instance is writable.
public bool IsWritable
{
get;
set;
}Property Value
Methods
Equals(XmpTrailerPi)
Indicates whether the current object is equal to another object of the same type.
public bool Equals(XmpTrailerPi other)
{
}Parameters
other XmpTrailerPi
An object to compare with this object.
Returns
true if the current object is equal to the other’ parameter; otherwise, false.
Equals(object)
Determines whether the specified System.Object, is equal to this instance.
public override bool Equals(object obj)
{
}Parameters
obj object
The System.Object to compare with this instance.
Returns
’true’ if the specified System.Object is equal to this instance; otherwise, ‘false’.
GetHashCode()
Returns a hash code for this instance.
public override int GetHashCode()
{
}Returns
A hash code for this instance, suitable for use in hashing algorithms and data structures like a hash table.
GetXmlValue()
Converts xmp value to the xml representation.
public string GetXmlValue()
{
}
In order to make this example more meaningful, I'll add some sample code inside the `GetXmlValue()` method:
public string GetXmlValue()
{
var xmlDocument = new XmlDocument();
xmlDocument.Load("myFile.xml");
var node = xmlDocument.SelectSingleNode("//myNode");
return node != null ? node.InnerText : String.Empty;
}Returns
Returns XML representation of XMP.
