Constructors

Name	Description
GcSkiaGraphics(int, int, bool, Color?)	Initializes a new instance of the GcSkiaGraphics.

Properties

Name	Description
Aliased	Gets or sets a value indicating whether the graphic objects are drawn without anti-aliasing. The default is false.
FontCache	Gets or sets the shared instance of a SkiaFontCache object.
Height	Gets the height of the image, in device-independent pixels (1/96 of an inch).
Opaque	Gets a value indicating whether the alpha channel should be ignored.
ResizeQuality	Gets or sets the resizing filter quality for images. The default is Medium.
Resolution	Gets the resolution of the current graphics, which is always 96 for GcSkiaGraphics.
SKCanvas	Gets the underlying SkiaSharp.SKCanvas object.
SurfaceResolution	Gets the resolution of the underlying drawing surface (pixels per inch).
Transform	Gets or sets the transformation matrix of the current graphics.
Width	Gets the width of the image, in device-independent pixels (1/96 of an inch).

Methods

Name	Description
ApplyLicenseKey(string)	Applies a license key to the current instance of GcSkiaGraphics.
Clear(Color)	Clears the drawing surface with the specified color.
Dispose(bool)	Performs cleanup operations on managed and unmanaged resources.
GetBlendMode()	For internal use. Returns the current blend mode.
GetInterpolationMode()	For internal use.
InternalCreateClipRegion(IPath)	For internal use.
InternalCreateClipRegion(RectangleF)	For internal use.
InternalCreatePath()	For internal use.
InternalDrawEllipse(RectangleF, Pen)	For internal use.
InternalDrawImage(RectangleF, IImage, float)	For internal use.
InternalDrawLine(PointF, PointF, Pen)	For internal use.
InternalDrawLines(PointF[], Pen)	For internal use.
InternalDrawPath(IPath, Pen)	For internal use.
InternalDrawPolygon(PointF[], Pen)	For internal use.
InternalDrawRectangle(RectangleF, Pen)	For internal use.
InternalDrawRoundRect(RectangleF, float, float, Pen)	For internal use.
InternalDrawTextLayout(TextLayout, PointF)	For internal use.
InternalDrawTextLayoutAsPath(TextLayout, PointF)	Draws a TextLayout at a specified location using graphic primitives.
InternalFillEllipse(RectangleF, Brush, RectangleF?, Matrix3x2?)	For internal use.
InternalFillEllipse(RectangleF, Color)	For internal use.
InternalFillPath(IPath, Brush, RectangleF?, Matrix3x2?)	For internal use.
InternalFillPath(IPath, Color)	For internal use.
InternalFillPolygon(PointF[], Brush, FillMode, RectangleF?, Matrix3x2?)	For internal use.
InternalFillPolygon(PointF[], Color, FillMode)	For internal use.
InternalFillRectangle(RectangleF, Brush, RectangleF?, Matrix3x2?)	For internal use.
InternalFillRectangle(RectangleF, Color)	For internal use.
InternalFillRoundRect(RectangleF, float, float, Brush, RectangleF?, Matrix3x2?)	For internal use.
InternalFillRoundRect(RectangleF, float, float, Color)	For internal use.
InternalRemoveClip(IClipRegion)	For internal use.
InternalSetClip(IClipRegion)	For internal use.
IsBlendModeSupported(BlendMode)	Indicates whether this graphics implementation supports a specified blend mode. GcSkiaGraphics supports all blend modes, so this method always returns true.
IsInterpolationModeSupported(InterpolationMode)	Indicates whether this graphics implementation supports a specified interpolation mode. The following interpolation modes are supported by GcSkiaGraphics: NearestNeighbor Linear Cubic
PopTransparencyLayer()	Stops redirecting drawing operations to the transparency layer that was created by the last PushTransparencyLayer(RectangleF?, float) call.
PushTransparencyLayer(RectangleF?, float)	Adds a transparency layer to the GcSkiaGraphics so that it receives all subsequent drawing operations until PopTransparencyLayer() is called.
SetBlendMode(BlendMode)	For internal use. Sets the current blend mode.
SetInterpolationMode(InterpolationMode)	For internal use.
SetLicenseKey(string)	Sets the license key.
ToGcBitmap(GcBitmap, Rectangle?)	Copies the image into an existing instance of GcBitmap.
ToGcBitmap(Rectangle?)	Creates an instance of the GcBitmap class from the current GcSkiaGraphics.
ToSkiaImage(Rectangle?)	Creates an instance of the GcSkiaImage class from the current GcSkiaGraphics.
