feature -- Access

	frozen black_on_white, stretch_andscans: INTEGER = 1
			-- Performs a Boolean AND operation using the color values for the eliminated
			-- and existing pixels. If the bitmap is a monochrome bitmap, this mode
			-- preserves black pixels at the expense of white pixels.

	frozen color_on_color, stretch_deletescans: INTEGER = 3
			-- Deletes the pixels. This mode deletes all eliminated lines of
			-- pixels without trying to preserve their information.

	frozen white_on_black, stretch_orscans: INTEGER = 2

	frozen halftone, stretch_halftone: INTEGER = 4
			-- Maps pixels from the source rectangle into blocks of pixels in the
			-- destination rectangle. The average color over the destination block
			-- of pixels approximates the color of the source pixels.
			-- After setting the HALFTONE stretching mode, an application must call the
			-- SetBrushOrgEx function to set the brush origin. If it fails to do so,
			-- brush misalignment occurs.

feature -- Status report

	valid_stretch_mode_constant (c: INTEGER): BOOLEAN
			-- Is `c' a valid stretch mode constant?
