Detailed Description

template<uint8_t BPP>
class AdafruitCanvasOps< BPP >

This is basic template class for all canvas classes, based on Adafruit_GFX. This base class provides functionality compatible with native NanoCanvas implementation of the library

Constructor & Destructor Documentation

AdafruitCanvasOps()

template<uint8_t BPP>

AdafruitCanvasOps< BPP >::AdafruitCanvasOps ( lcduint_t  w, lcduint_t  h, uint8_t *  buffer  )

inline

Initializes canvas, based on Adafruit GFX.

Parameters

w	width of canvas
h	height of canvas area
buffer	buffer to use for pixels

Note

the size of buffer must be enough to store (w*h*bpp/8) bytes.

drawPixel()

template<uint8_t BPP>

void AdafruitCanvasOps< BPP >::drawPixel ( int16_t  x, int16_t  y, uint16_t  color  )

override

draw single pixel in canvas area

Parameters

x	x position
y	y position
color	color of pixel: for monochrome it can be 0 (black), 1 (white), 2 (invert)

setOffset()

template<uint8_t BPP>

void AdafruitCanvasOps< BPP >::setOffset ( lcdint_t  ox, lcdint_t  oy  )
