GrapeCity.Documents.Imaging.Windows.GcD2DBitmapGraphics

Class GcD2DBitmapGraphics

Namespace
GrapeCity.Documents.Imaging.Windows
Assembly
GcDocs.Imaging.Windows.dll

Implements a Direct2D drawing surface.

To create an instance of this class, use the CreateGraphics(Color?) method. 

public class GcD2DBitmapGraphics : GcDXGraphics, IDisposable
Inheritance
object
GcD2DBitmapGraphics
Implements
System.IDisposable
Inherited Members
object.ToString()
object.Equals(object)
object.Equals(object, object)
object.ReferenceEquals(object, object)
object.GetHashCode()
object.GetType()
object.MemberwiseClone()

Fields

Bitmap

The owning GcD2DBitmap object.

public readonly GcD2DBitmap Bitmap

Field Value

GcD2DBitmap

Properties

Features 

public override GcGraphicsFeatures Features { get; }

Property Value

GrapeCity.Documents.Drawing.GcGraphicsFeatures

SurfaceResolution

Gets the resolution of the underlying drawing surface (pixels per inch).

public override float? SurfaceResolution { get; }

Property Value

float?

Methods

AfterDrawAction()

Called after any draw action on the underlying render target.

protected override void AfterDrawAction()

BeforeDrawAction()

Called before any draw action on the underlying render target.

protected override void BeforeDrawAction()

Composite(IGcTransparencyGroup, Rectangle, Point, float?) 

public override void Composite(IGcTransparencyGroup srcLayer, Rectangle srcBounds, Point dstPosition, float? alpha)

Parameters

srcLayer GrapeCity.Documents.Drawing.IGcTransparencyGroup
srcBounds System.Drawing.Rectangle
dstPosition System.Drawing.Point
alpha float?

CreateTransparencyGroup(Rectangle, bool, bool, bool) 

public override IGcTransparencyGroup CreateTransparencyGroup(Rectangle size, bool isolated, bool knockout, bool pdfSoftMask)

Parameters

size System.Drawing.Rectangle
isolated bool
knockout bool
pdfSoftMask bool

Returns

GrapeCity.Documents.Drawing.IGcTransparencyGroup

CreateTransparencyMask(IGcTransparencyGroup, TransparencyMaskType, Rectangle) 

public override object CreateTransparencyMask(IGcTransparencyGroup layer, TransparencyMaskType maskType, Rectangle maskBounds)

Parameters

layer GrapeCity.Documents.Drawing.IGcTransparencyGroup
maskType GrapeCity.Documents.Drawing.TransparencyMaskType
maskBounds System.Drawing.Rectangle

Returns

object

Dispose(bool)

Performs cleanup operations on managed and unmanaged resources.

protected override void Dispose(bool disposing)

Parameters

disposing bool

GetBlendMode()

For internal use. Returns the current blend mode.

protected override BlendMode GetBlendMode()

Returns

BlendMode

InternalCreateClipRegion(IPath)

For internal use.

protected override IClipRegion InternalCreateClipRegion(IPath graphicsPath)

Parameters

graphicsPath IPath

Returns

IClipRegion

InternalCreateClipRegion(RectangleF)

For internal use.

protected override IClipRegion InternalCreateClipRegion(RectangleF bounds)

Parameters

bounds System.Drawing.RectangleF

Returns

IClipRegion

IsBlendModeSupported(BlendMode)

Indicates whether this graphics implementation supports a specified blend mode.

GcD2DBitmapGraphics supports all blend modes, so this method always returns true.

public override bool IsBlendModeSupported(BlendMode blendMode)

Parameters

blendMode BlendMode

The blend mode to check.

Returns

bool

true.

PopTransparencyLayer()

Stops redirecting drawing operations to the transparency layer that was created by the last PushTransparencyLayer(RectangleF?, float) call.

public override void PopTransparencyLayer()

PushTransparencyLayer(RectangleF?, float)

Adds a transparency layer to the current graphics. That layer receives all subsequent drawing operations until PopTransparencyLayer() is called.

public override void PushTransparencyLayer(RectangleF? contentBounds, float opacity)

Parameters

contentBounds System.Drawing.RectangleF?

The content bounds of the transparency layer. Content won't render outside these bounds. When set to null, the content bounds are effectively taken to be the bounds of the current graphics.

opacity float

An opacity value that is applied uniformly to all drawings in the layer when compositing to the backplate.

SetBlendMode(BlendMode)

For internal use. Sets the current blend mode.

protected override void SetBlendMode(BlendMode value)

Parameters

value BlendMode

SetTransparencyMask(object) 

public override void SetTransparencyMask(object nativeMask)

Parameters

nativeMask object
