Data Structures
struct	tintColor_t
	A set of colors used to tint a greyscale image. More...

Macros
#define	PALETTE_LOWLIGHT   c111
	Palette lowlight color to be tinted in grayscale images. See tintPalette()
#define	PALETTE_BASE   c222
	Palette base color to be tinted in grayscale images. See tintPalette()
#define	PALETTE_HIGHLIGHT   c444
	Palette hightlight color to be tinted in grayscale images. See tintPalette()

Functions
void	tintPalette (wsgPalette_t *palette, const tintColor_t *tintColor)
	Modifies a palette to be used for tinting greyscale images. The resulting palette is intended to be used with the wsgPalette* functions.
void	drawToCanvas (wsg_t canvas, wsg_t wsg, uint16_t x, uint16_t y)
	Draws a wsg image onto another wsg image.
void	drawToCanvasTint (wsg_t canvas, wsg_t wsg, int32_t x, int32_t y, int32_t rotationDeg, const tintColor_t *tintColor)
	Draws a wsg image drawn in greyscale onto another wsg image, tinting the grayscale pixels. This function can be used to tint a greyscale image in place.
void	drawToCanvasTile (wsg_t canvas, wsg_t wsg, uint16_t x, uint16_t y)
	Draws a wsg image onto another wsg image without taking transparent pixels into account.

Function Documentation

tintPalette()

void tintPalette	(	wsgPalette_t *	palette,
		const tintColor_t *	tintColor )

Modifies a palette to be used for tinting greyscale images. The resulting palette is intended to be used with the wsgPalette* functions.

Parameters

palette	The palette to be modified
tintColor	The color set to apply to the grey tones of the palette

drawToCanvas()

void drawToCanvas	(	wsg_t	canvas,
		wsg_t	wsg,
		uint16_t	x,
		uint16_t	y )

Draws a wsg image onto another wsg image.

Parameters

canvas	A wsg to draw onto
wsg	The image to draw to the canvas
x	x position to draw the wsg
y	y position to draw the wsg

drawToCanvasTint()

void drawToCanvasTint	(	wsg_t	canvas,
		wsg_t	wsg,
		int32_t	x,
		int32_t	y,
		int32_t	rotationDeg,
		const tintColor_t *	tintColor )

Draws a wsg image drawn in greyscale onto another wsg image, tinting the grayscale pixels. This function can be used to tint a greyscale image in place.

Parameters

canvas	A wsg to draw onto
wsg	The image to draw to the canvas
x	x position to draw the wsg
y	y position to draw the wsg
rotationDeg
tintColor	The color used to tint a greyscale wsg

drawToCanvasTile()

void drawToCanvasTile	(	wsg_t	canvas,
		wsg_t	wsg,
		uint16_t	x,
		uint16_t	y )

Draws a wsg image onto another wsg image without taking transparent pixels into account.

Parameters

canvas	A wsg to draw onto
wsg	The image to draw to the canvas
x	x position to draw the wsg
y	y position to draw the wsg
