Function Documentation

apply_color_alpha()

void platf::dxgi::apply_color_alpha	(	int *	img_pixel_p,
		int	cursor_pixel )

Alpha-blend a color cursor pixel into a captured RAM frame.

Parameters

img_pixel_p	Pixel in the destination frame.
cursor_pixel	ARGB cursor pixel to blend.

apply_color_masked()

void platf::dxgi::apply_color_masked	(	int *	img_pixel_p,
		int	cursor_pixel )

Apply a masked-color cursor pixel into a captured RAM frame.

Parameters

img_pixel_p	Pixel in the destination frame.
cursor_pixel	ARGB cursor pixel with masked-cursor semantics.

blend_cursor()

void platf::dxgi::blend_cursor	(	const cursor_t &	cursor,
		img_t &	img )

Blend the current cursor image into a RAM frame.

Parameters

cursor	Cursor image or visibility state to composite.
img	Image or frame object to read from or populate.

blend_cursor_color()

void platf::dxgi::blend_cursor_color	(	const cursor_t &	cursor,
		img_t &	img,
		const bool	masked )

Blend a color cursor shape into a RAM frame.

Parameters

cursor	Cursor image or visibility state to composite.
img	Image or frame object to read from or populate.
masked	Whether the cursor image uses an AND/XOR mask.

blend_cursor_monochrome()

void platf::dxgi::blend_cursor_monochrome	(	const cursor_t &	cursor,
		img_t &	img )

Blend a monochrome cursor shape into a RAM frame.

Parameters

cursor	Cursor image or visibility state to composite.
img	Image or frame object to read from or populate.
