FreeImage.NET Class Library Reference

The FIMETADATA structure is an unique search handle for metadata search operations.

Namespace: FreeImageAPI
Assembly: FreeImageNET (in FreeImageNET.dll) Version: 3.17.0.4 (3.17.0)

Syntax

[SerializableAttribute]
public struct FIMETADATA : IComparable, 
	IComparable<FIMETADATA>, IEquatable<FIMETADATA>

The FIMETADATA type exposes the following members.

Properties

	Name	Description
	IsNull	Gets whether the pointer is a null pointer or not.

Methods

	Name	Description
	CompareTo(Object)	Compares this instance with a specified Object.
	CompareTo(FIMETADATA)	Compares this instance with a specified FIMETADATA object.
	Equals(Object)	Determines whether the specified Object is equal to the current Object. (Overrides ValueTypeEquals(Object).)
	Equals(FIMETADATA)	Indicates whether the current object is equal to another object of the same type.
	GetHashCode	Returns a hash code for this FIMETADATA structure. (Overrides ValueTypeGetHashCode.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	SetNull	Sets the handle to null.
	ToString	Converts the numeric value of the FIMETADATA object to its equivalent string representation. (Overrides ValueTypeToString.)

Operators

	Name	Description
	Equality	Tests whether two specified FIMETADATA structures are equivalent.
	Inequality	Tests whether two specified FIMETADATA structures are different.

Fields

	Name	Description
	Zero	A read-only field that represents a handle that has been initialized to zero.

Remarks

The FIMETADATA structure is usually returned by the FindFirstMetadata(FREE_IMAGE_MDMODEL, FIBITMAP, FITAG) function and then used on subsequent calls to FindNextMetadata(FIMETADATA, FITAG). When the FIMETADATA handle is no longer used, it needs to be freed by the FindCloseMetadata(FIMETADATA) function.
