Member Function Documentation

blt() [1/3]

template<uint8_t BPP>

virtual void NanoCanvasBase< BPP >::blt ( lcdint_t  x, lcdint_t  y  )

pure virtual

Draws canvas on the LCD display

Parameters

x	- horizontal position in pixels
y	- vertical position in blocks (pixels/8)

Implemented in NanoCanvas16, NanoCanvas8, NanoCanvas1_4, NanoCanvas1_16, NanoCanvas1_8, and NanoCanvas1.

blt() [2/3]

template<uint8_t BPP>

virtual void NanoCanvasBase< BPP >::blt ( )

pure virtual

Draws canvas on the LCD display using offset values.

Implemented in NanoCanvas16, NanoCanvas8, NanoCanvas1_4, NanoCanvas1_16, NanoCanvas1_8, and NanoCanvas1.

blt() [3/3]

template<uint8_t BPP>

virtual void NanoCanvasBase< BPP >::blt ( const NanoRect &  rect )

pure virtual

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.

Implemented in NanoCanvas16, NanoCanvas8, NanoCanvas1_4, NanoCanvas1_16, NanoCanvas1_8, and NanoCanvas1.
