Color Gosu::Bitmap::getPixel	(	unsigned	x,
		unsigned	y
	)			const [inline]

Returns the color at the specified position.

x and y must be on the bitmap.

void Gosu::Bitmap::setPixel	(	unsigned	x,
		unsigned	y,
		Color	c
	)			[inline]

Sets the pixel at the specified position to a color.

x and y must be on the bitmap.

void Gosu::Bitmap::insert	(	const Bitmap &	source,
		int	x,
		int	y
	)

Inserts a bitmap at the given position.

Parts of the inserted bitmap that would be outside of the target bitmap will be clipped away.

void Gosu::Bitmap::insert	(	const Bitmap &	source,
		int	x,
		int	y,
		unsigned	srcX,
		unsigned	srcY,
		unsigned	srcWidth,
		unsigned	srcHeight
	)

Inserts a portion of a bitmap at the given position.

Parts of the inserted bitmap that would be outside of the target bitmap will be clipped away.
