	ScopedBlendContextOptions (BlendMode mode)
	Creates an object using the provided blend mode.

ScopedBlendContextOptions	withBlendMode (BlendMode x) const
	Specifies the blend mode to be applied when blending the backing buffer into the parent buffer.

ScopedBlendContextOptions	withLuminanceMaskSet (bool x=true) const
	When this option is set, the backing buffer's luminosity is converted to alpha values prior to blending it into the parent buffer.

ScopedBlendContextOptions	withScopeClip (Rectangle< int > x) const
	Allows specifying an additional clip for the blend context, reducing the necessary size of the backing buffer.

ScopedBlendContextOptions	withOpacity (float x) const
	Allows specifying an additional opacity value that is applied prior to blending the buffer into the parent.

◆ withBlendMode()

ScopedBlendContextOptions juce::ScopedBlendContextOptions::withBlendMode ( BlendMode x ) const

inline

Specifies the blend mode to be applied when blending the backing buffer into the parent buffer.

◆ withLuminanceMaskSet()

ScopedBlendContextOptions juce::ScopedBlendContextOptions::withLuminanceMaskSet ( bool x = true ) const

inline

When this option is set, the backing buffer's luminosity is converted to alpha values prior to blending it into the parent buffer.

After conversion, the RGB components are zero, and the A component is calculated using the equation in the SVG specification A = ((0.2125 * R) + (0.7154 * G) + (0.0721 * B)) * A.

◆ withScopeClip()

ScopedBlendContextOptions juce::ScopedBlendContextOptions::withScopeClip ( Rectangle< int > x ) const

inline

Allows specifying an additional clip for the blend context, reducing the necessary size of the backing buffer.

By default the backing buffer will be the same size as the parent context's clip region. Even if this value is provided, it is ignored for certain blending modes such as destinationIn and destinationOut.
