Member Function Documentation

◆ blt() [1/3]

void NanoCanvas1_4::blt	(	lcdint_t	x,
		lcdint_t	y
	)

overridevirtual

Draws canvas on the LCD display

Parameters

x	- horizontal position in pixels
y	- vertical position in pixels

Implements NanoCanvasBase< 4 >.

◆ blt() [2/3]

void NanoCanvas1_4::blt ( )

overridevirtual

Draws canvas on the LCD display using offset values.

Implements NanoCanvasBase< 4 >.

◆ blt() [3/3]

void NanoCanvas1_4::blt ( const NanoRect & rect )

overridevirtual

Draws only part of canvas on the LCD display. This method uses Canvas offset field as top-left point of whole canvas content. First point of specified rectangle defines the actual top-left point on the screen to be refreshed. For example, blt({{8,0},{15,7}}); will copy canvas area {8,0}-{15,7} to screen starting at {8,0} if canvas offset is {0,0}. If canvas offset is {12,3}, then canvas area {8,0}-{15,7} will be copied to screen at position {20,3}.

Parameters

rect	rectagle describing part of canvas to move to display.

Implements NanoCanvasBase< 4 >.
