Syntax

public sealed class DWriteFontFile : IDisposable, IDWriteReleasable

Properties

Handle

Gets an handle representing the DWrite object interface.

Declaration

public object Handle { get; }

Property Value

Type	Description
object

Methods

Analyse(out bool, out DWriteFontFileType, out DWriteFontFaceType, out uint)

Analyzes a file and returns whether it represents a font, and whether the font type is supported by the font system.

Declaration

public void Analyse(out bool isSupportedFontType, out DWriteFontFileType fontFileType, out DWriteFontFaceType fontFaceType, out uint numberOfFaces)

Parameters

Type	Name	Description
bool	isSupportedFontType	TRUE if the font type is supported by the font system, FALSE otherwise.
DWriteFontFileType	fontFileType	The type of the font file. Note that even if isSupportedFontType is FALSE, the fontFileType value may be different from DWRITE_FONT_FILE_TYPE_UNKNOWN.
DWriteFontFaceType	fontFaceType	The type of the font face that can be constructed from the font file. Note that even if isSupportedFontType is FALSE, the fontFaceType value may be different from DWRITE_FONT_FACE_TYPE_UNKNOWN.
uint	numberOfFaces	Number of font faces contained in the font file.

Remarks

IMPORTANT: certain font file types are recognized, but not supported by the font system. For example, the font system will recognize a file as a Type 1 font file, but will not be able to construct a font face object from it. In such situations, Analyze will set isSupportedFontType output parameter to FALSE.

Dispose()

Immediately releases the unmanaged resources used by the DWrite object.

Declaration

public void Dispose()

GetReferenceKey()

Gets the reference key of a font file.

Declaration

public byte[] GetReferenceKey()

Returns

Type	Description
byte[]	byte

Release()

Releases the managed reference to the COM DWrite interface.

Declaration

public void Release()

ToBoolean()

Gets a boolean indicating if the handle is not null.

Declaration

public bool ToBoolean()

Returns

Type	Description
bool	A boolean

Operators

implicit operator bool(DWriteFontFile)

Gets a boolean indicating if the handle is not null.

Declaration

public static implicit operator bool(DWriteFontFile value)

Parameters

Type	Name	Description
DWriteFontFile	value	A DWrite object.

Returns

Type	Description
bool	A boolean
