Functions
EMSTATUS	GLIB_applyClippingRegion (const GLIB_Context_t *pContext)
	Apply the clipping region from the GLIB_Context_t in the DMD driver.

EMSTATUS	GLIB_clear ( GLIB_Context_t *pContext)
	Clears the display with the background color of the GLIB_Context_t.

EMSTATUS	GLIB_clearRegion (const GLIB_Context_t *pContext)
	Clears the clipping region by filling it with the background color of the GLIB_Context_t.

void	GLIB_colorTranslate24bpp (uint32_t color, uint8_t red, uint8_t green, uint8_t *blue)
	Extracts the color components from the 32-bit color passed and puts them in the passed in 8-bits ints. The color is 24-bit RGB.

EMSTATUS	GLIB_contextInit ( GLIB_Context_t *pContext)
	Initialize the GLIB_Context_t.

EMSTATUS	GLIB_displaySleep ()
	Sets the display in sleep mode.

EMSTATUS	GLIB_displayWakeUp ()
	Returns the display from sleep mode.

EMSTATUS	GLIB_drawPixel ( GLIB_Context_t *pContext, int32_t x, int32_t y)
	Draws a pixel at x, y using foregroundColor defined in the GLIB_Context_t.

EMSTATUS	GLIB_drawPixelColor ( GLIB_Context_t *pContext, int32_t x, int32_t y, uint32_t color)
	Draws a pixel at x, y using the color parameter.

EMSTATUS	GLIB_drawPixelRGB ( GLIB_Context_t *pContext, int32_t x, int32_t y, uint8_t red, uint8_t green, uint8_t blue)
	Draws a pixel at x, y with color defined by red, green and blue 1 byte per channel.

EMSTATUS	GLIB_resetClippingRegion ( GLIB_Context_t *pContext)
	Reset the GLIB_Context_t clipping region to the whole display.

EMSTATUS	GLIB_resetDisplayClippingArea ( GLIB_Context_t *pContext)
	Reset the display driver clipping area to the whole display.

uint32_t	GLIB_rgbColor (uint8_t red, uint8_t green, uint8_t blue)
	Convert 3 uint8_t color components into a 24-bit color.

EMSTATUS	GLIB_setClippingRegion ( GLIB_Context_t pContext, const GLIB_Rectangle_t pRect)
	Sets the clippingRegion of the passed in GLIB_Context_t.

Macro Definition Documentation

#define GLIB_DEFAULT_FONT (( GLIB_Font_t *)& GLIB_FontNormal8x8 )

Define the default font. An application can override the default font by defining GLIB_NO_DEFAULT_FONT and by providing a custom GLIB_DEFAULT_FONT macro that points to a GLIB_Font_t structure that should be used as a default font.
