IsBlendModeSupported(BlendMode)

Indicates whether this graphics implementation supports a specified blend mode.

GcBitmapGraphics 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.

IsInterpolationModeSupported(InterpolationMode)

Indicates whether this graphics implementation supports a specified interpolation mode.

GcBitmapGraphics supports all interpolation modes, so this method always returns true.

public override bool IsInterpolationModeSupported(InterpolationMode interpolationMode)

Parameters

interpolationMode InterpolationMode

The interpolation mode to check.

Returns

bool

true if the specified interpolation mode is supported by GcBitmapGraphics, false otherwise.

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

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

Parameters

contentBounds 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 GcBitmapGraphics.
