Functions
EMSTATUS	GLIB_applyClippingRegion (const GLIB_Context_t *pContext)
	Apply the clipping region from the GLIB_Context_t in the DMD driver. More...
EMSTATUS	GLIB_clear (GLIB_Context_t *pContext)
	Clears the display with the background color of the GLIB_Context_t. More...
EMSTATUS	GLIB_clearRegion (const GLIB_Context_t *pContext)

	Draws a pixel at x, y with color defined by red, green and blue 1 byte per channel. More...
EMSTATUS	GLIB_resetClippingRegion (GLIB_Context_t *pContext)
	Reset the GLIB_Context_t clipping region to the whole display. More...
EMSTATUS	GLIB_resetDisplayClippingArea (GLIB_Context_t *pContext)
	Reset the display driver clipping area to the whole display. More...
uint32_t	GLIB_rgbColor (uint8_t red, uint8_t green, uint8_t blue)
	Convert 3 uint8_t color components into a 24-bit color. More...

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.
