NameDescription
System_CAPS_pubmethod GlyphRunDrawing

Initializes a new instance of the GlyphRunDrawing class.

System_CAPS_pubmethod GlyphRunDrawing

Initializes a new instance of the GlyphRunDrawing class by specifying the foreground brush and GlyphRun.

NameDescription
System_CAPS_pubproperty

Gets the axis-aligned bounds of the drawing's contents. (Inherited from Drawing.)

System_CAPS_pubproperty

Gets a value that indicates whether the object can be made unmodifiable. (Inherited from Freezable.)

System_CAPS_pubproperty

Gets the DependencyObjectType that wraps the CLR type of this instance. (Inherited from DependencyObject.)

System_CAPS_pubproperty

Gets the Dispatcher this DispatcherObject is associated with. (Inherited from DispatcherObject.)

System_CAPS_pubproperty

Gets or sets the foreground brush of the GlyphRunDrawing.

System_CAPS_pubproperty

Gets or sets the GlyphRun that describes the text to draw.

System_CAPS_pubproperty

Gets a value that indicates whether one or more AnimationClock objects is associated with any of this object's dependency properties.(Inherited from Animatable.)

System_CAPS_pubproperty

Gets a value that indicates whether the object is currently modifiable. (Inherited from Freezable.)

System_CAPS_pubproperty

Gets a value that indicates whether this instance is currently sealed (read-only).(Inherited from DependencyObject.)

NameDescription
System_CAPS_pubmethod ApplyAnimationClock

Applies an AnimationClock to the specified DependencyProperty. If the property is already animated, the SnapshotAndReplace handoff behavior is used.(Inherited from Animatable.)

System_CAPS_pubmethod ApplyAnimationClock

Applies an AnimationClock to the specified DependencyProperty. If the property is already animated, the specified HandoffBehavior is used.(Inherited from Animatable.)

System_CAPS_pubmethod BeginAnimation

Applies an animation to the specified DependencyProperty. The animation is started when the next frame is rendered. If the specified property is already animated, the SnapshotAndReplace handoff behavior is used.(Inherited from Animatable.)

System_CAPS_pubmethod BeginAnimation

Applies an animation to the specified DependencyProperty. The animation is started when the next frame is rendered. If the specified property is already animated, the specified HandoffBehavior is used. (Inherited from Animatable.)

System_CAPS_pubmethod CheckAccess

Determines whether the calling thread has access to this DispatcherObject.(Inherited from DispatcherObject.)

System_CAPS_pubmethod ClearValue

Clears the local value of a property. The property to be cleared is specified by a DependencyProperty identifier. (Inherited from DependencyObject.)

System_CAPS_pubmethod ClearValue

Clears the local value of a read-only property. The property to be cleared is specified by a DependencyPropertyKey. (Inherited from DependencyObject.)

System_CAPS_pubmethod Clone

Creates a modifiable clone of this GlyphRunDrawing, making deep copies of this object's values. When copying dependency properties, this method copies resource references and data bindings (but they might no longer resolve) but not animations or their current values.

System_CAPS_pubmethod CloneCurrentValue

Creates a modifiable clone of this GlyphRunDrawing object, making deep copies of this object's current values. Resource references, data bindings, and animations are not copied, but their current values are.

System_CAPS_pubmethod CoerceValue

Coerces the value of the specified dependency property. This is accomplished by invoking any CoerceValueCallback function specified in property metadata for the dependency property as it exists on the calling DependencyObject.(Inherited from DependencyObject.)

System_CAPS_pubmethod Equals

Determines whether a provided DependencyObject is equivalent to the current DependencyObject.(Inherited from DependencyObject.)

System_CAPS_pubmethod Freeze

Makes the current object unmodifiable and sets its property to true. (Inherited from Freezable.)

System_CAPS_pubmethod GetAnimationBaseValue

Returns the non-animated value of the specified DependencyProperty.(Inherited from Animatable.)

System_CAPS_pubmethod GetAsFrozen

Creates a frozen copy of the Freezable, using base (non-animated) property values. Because the copy is frozen, any frozen sub-objects are copied by reference. (Inherited from Freezable.)

System_CAPS_pubmethod GetCurrentValueAsFrozen

Creates a frozen copy of the Freezable using current property values. Because the copy is frozen, any frozen sub-objects are copied by reference.(Inherited from Freezable.)

System_CAPS_pubmethod GetHashCode

Gets a hash code for this DependencyObject.(Inherited from DependencyObject.)

System_CAPS_pubmethod GetLocalValueEnumerator

Creates a specialized enumerator for determining which dependency properties have locally set values on this DependencyObject. (Inherited from DependencyObject.)

System_CAPS_pubmethod GetType

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_pubmethod GetValue

Returns the current effective value of a dependency property on this instance of a DependencyObject. (Inherited from DependencyObject.)

System_CAPS_pubmethod InvalidateProperty

Re-evaluates the effective value for the specified dependency property(Inherited from DependencyObject.)

System_CAPS_pubmethod ReadLocalValue

Returns the local value of a dependency property, if it exists. (Inherited from DependencyObject.)

System_CAPS_pubmethod SetCurrentValue

Sets the value of a dependency property without changing its value source. (Inherited from DependencyObject.)

System_CAPS_pubmethod SetValue

Sets the local value of a dependency property, specified by its dependency property identifier. (Inherited from DependencyObject.)

System_CAPS_pubmethod SetValue

Sets the local value of a read-only dependency property, specified by the DependencyPropertyKey identifier of the dependency property. (Inherited from DependencyObject.)

System_CAPS_protmethod ShouldSerializeProperty

Returns a value that indicates whether serialization processes should serialize the value for the provided dependency property.(Inherited from DependencyObject.)

System_CAPS_pubmethod ToString

Returns a string that represents the current object.(Inherited from Object.)

System_CAPS_pubmethod VerifyAccess

Enforces that the calling thread has access to this DispatcherObject.(Inherited from DispatcherObject.)

NameDescription
System_CAPS_pubfield System_CAPS_static ForegroundBrushProperty

Identifies the  dependency property.

System_CAPS_pubfield System_CAPS_static GlyphRunProperty

Identifies the  dependency property.

NameDescription
System_CAPS_pubevent Changed

Occurs when the Freezable or an object it contains is modified. (Inherited from Freezable.)

The GlyphRun object represents a sequence of glyphs from a single face of a single font at a single size, and with a single rendering style.

GlyphRun contains font details such as glyph indices and individual glyph positions. In addition, GlyphRun contains the original Unicode code points the run was generated from, character to glyph buffer offset mapping information, and per-character and per-glyph flags.

Each glyph in a GlyphRun defines metrics that specify how it aligns with other Glyphs. The following graphic defines the various typographic qualities of two different glyph characters.

Freezable Features: A GlyphRunDrawing is a type of Freezable object and therefore can be frozen to improve performance. For information about Freezable features, such as freezing and cloning, see the Freezable Objects Overview.

Caution: GlyphRunDrawing objects do not support partial trust execution. An application must have full trust permissions to use GlyphRunDrawing objects.

The following example uses a GlyphRunDrawing to draw the text "Hello World".

GlyphRun theGlyphRun = new GlyphRun(
    new GlyphTypeface(new Uri(@"C:\WINDOWS\Fonts\TIMES.TTF")),
    0,
    false,
    13.333333333333334,
    new ushort[]{43, 72, 79, 79, 82, 3, 58, 82, 85, 79, 71},
    new Point(0, 12.29),
    new double[]{

A GlyphRun is a low-level object intended for use with fixed-format document presentation and print scenarios. A simpler way to draw text to the screen is to use a Label or a TextBlock. For more information about GlyphRun, see the Introduction to the GlyphRun Object and Glyphs Element overview.
