	Return a copy of this image.
	~alpha ()
bool	make_next_miplevel ()
	Fast, in-place resample. For making mip-maps. Munges the input image to produce the output image.

Member Function Documentation

std::auto_ptr<image_base> image::alpha::clone

(

)

const [inline, virtual]

Return a copy of this image.

Implements image::image_base.

bool image::alpha::make_next_miplevel

(

)

[virtual]

Fast, in-place resample. For making mip-maps. Munges the input image to produce the output image.

Returns:

true if resample happened, false otherwise (image can't be shrinked, for example)

Reimplemented from image::image_base.

void image::alpha::set_pixel	(	size_t	x,
		size_t	y,
		boost::uint8_t	a
	)

Set pixel value.

TODO: move in base class ?
