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
wwidth of canvas
hheight of canvas area
bufferbuffer 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
xx position
yy position
colorcolor 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 
)
inline

Sets offset

Parameters
ox- X offset in pixels
oy- Y offset in pixels
