Syntax

public class Freetype2 : SharedPtrObject, IAlgorithm

Public Class Freetype2
	Inherits SharedPtrObject
	Implements IAlgorithm

public ref class Freetype2 : public SharedPtrObject, 
	IAlgorithm

type Freetype2 =  
    class
        inherit SharedPtrObject
        interface IAlgorithm
    end

The Freetype2 type exposes the following members.

Constructors

	Name	Description
	Freetype2	Create instance to draw UTF-8 strings.

Properties

	Name	Description
	AlgorithmPtr	Native algorithm pointer
	Ptr	Pointer to the unmanaged object (Inherited from UnmanagedObject.)
	SharedPtr	Pointer to the shared pointer to the unmanaged object (Inherited from SharedPtrObject.)

Methods

	Name	Description
	Dispose	The dispose function that implements IDisposable interface (Inherited from DisposableObject.)
	DisposeObject	Release all the unmanaged memory associate with this object (Overrides DisposableObjectDisposeObject.)
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Finalize	Destructor (Inherited from DisposableObject.)
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetTextSize	Calculates the width and height of a text string.
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	LoadFontData	Load font data.
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	PutText	Renders the specified text string in the image. Symbols that cannot be rendered using the specified font are replaced by "Tofu" or non-drawn.
	ReleaseManagedResources	Release the managed resources. This function will be called during the disposal of the current object. override ride this function if you need to call the Dispose() function on any managed IDisposable object created by the current object (Inherited from DisposableObject.)
	SetSplitNumber	Set the number of split points from bezier-curve to line. If you want to draw large glyph, large is better. If you want to draw small glyph, small is better.
	ToString	Returns a string that represents the current object. (Inherited from Object.)

Fields

	Name	Description
	_ptr	A pointer to the unmanaged object (Inherited from UnmanagedObject.)
	_sharedPtr	A pointer to the shared pointer to the unmanaged object (Inherited from SharedPtrObject.)

Extension Methods

	Name	Description
	Clear	Clear the algorithm (Defined by AlgorithmExtensions.)
	GetDefaultName	Returns the algorithm string identifier. This string is used as top level xml/yml node tag when the object is saved to a file or string. (Defined by AlgorithmExtensions.)
	IsEmpty	Returns true if the Algorithm is empty. e.g. in the very beginning or after unsuccessful read. (Defined by AlgorithmExtensions.)
	Load	Loads algorithm from the file (Defined by AlgorithmExtensions.)
	LoadFromString	Loads algorithm from a String (Defined by AlgorithmExtensions.)
	Read	Reads algorithm parameters from a file storage. (Defined by AlgorithmExtensions.)
	Save	Save the algorithm to file (Defined by AlgorithmExtensions.)
	SaveToString	Save the algorithm to a string (Defined by AlgorithmExtensions.)
	Write(FileStorage)	Overloaded. Stores algorithm parameters in a file storage (Defined by AlgorithmExtensions.)
	Write(FileStorage, String)	Overloaded. Stores algorithm parameters in a file storage (Defined by AlgorithmExtensions.)
