Constructor & Destructor Documentation

PoissonFiller()

PoissonFiller::PoissonFiller	(	uint	width,
		uint	height,
		uint	downscaling
	)

Constructor.

Parameters

width	internal processing width
height	internal processing height
downscaling	downscaling factor for the internal convolution pyramid resolution

Member Function Documentation

preprocId()

const Texture * PoissonFiller::preprocId ( ) const

inline

The ID of the texture containing the colored border.

Returns

the border texture ID.

process()

void PoissonFiller::process

(

const Texture &

texture

)

Fill black regions of an image in a smooth fashion, first computing its border color before performing filling.

Parameters

texture

the GPU ID of the texture

resize()

void PoissonFiller::resize	(	uint	width,
		uint	height
	)

Resize the internal buffers.

Parameters

width	the new width
height	the new height

texture()

const Texture * PoissonFiller::texture ( ) const

inline

The ID of the texture containing the filled result.

Returns

the result texture ID.
