Constructor & Destructor Documentation

DropShadow::DropShadow ( )

noexcept

Creates a default drop-shadow effect.

noexcept

Creates a drop-shadow object with the given parameters.

void DropShadow::drawForImage	(	Graphics &	g,
		const Image &	srcImage
	)		const

Renders a drop-shadow based on the alpha-channel of the given image.

void DropShadow::drawForPath	(	Graphics &	g,
		const Path &	path
	)		const

Renders a drop-shadow based on the shape of a path.

void DropShadow::drawForRectangle	(	Graphics &	g,
		const Rectangle< int > &	area
	)		const

Renders a drop-shadow for a rectangle.

Note that for speed, this approximates the shadow using gradients.

Colour DropShadow::colour

The colour with which to render the shadow.

In most cases you'll probably want to leave this as black with an alpha value of around 0.5

int DropShadow::radius

The approximate spread of the shadow.

Point<int> DropShadow::offset

The offset of the shadow.
