Member Function Documentation

◆ clear()

template<class I >

void NanoDisplayOps8::clear ( )

Clears canvas

◆ drawBitmap1()

template<class I >

void NanoDisplayOps8< I >::drawBitmap1	(	lcdint_t	x,
		lcdint_t	y,
		lcduint_t	w,
		lcduint_t	h,
		const uint8_t *	bitmap
	)

Draws monochrome bitmap in color buffer using color, specified via setColor() method Draws monochrome bitmap in color buffer using color, specified via setColor() method.

Parameters

x	- position X in pixels
y	- position Y in pixels
w	- width in pixels
h	- height in pixels
bitmap	- monochrome bitmap data, located in flash

Note: There are 2 modes: transparent and non-transparent mode, - and 2 colors available: black and white. In non-transparent mode, when black color is selected, the monochrome image just inverted. In transparent mode, those pixels of source monochrome image, which are black, do not overwrite pixels in the screen buffer.
