Bitmap_16bitAlpha::Bitmap_16bitAlpha	(	int	width,
		int	height
	)

Creates an empty bitmap with the specified dimensions. All pixels will be set to black (0) at creation.

Parameters:

	width	The width of the bitmap, in pixels
	height	The height of the bitmap, in pixels

Definition at line 36 of file Bitmap_16bitAlpha.cpp.

Bitmap_16bitAlpha::Bitmap_16bitAlpha	(	const Image &	image,
		bool	dither = false
	)

Creates a bitmap from an Image. The width and the height of the bitmap will be taken from the image, the colors reduced from 32 to 16 bits, and the alpha channel is dropped.

Parameters:

image

Image to create bitmap from
