Matrix.drawRFrame()

Matrix.drawRFrame(x,y,w,h,r) 描述 画带倒角的空心距形。 参数 x：起点横坐标x y：起点横坐标x w：宽 h：高 r：倒角半径 返回值 无 示例 彩色点阵：Sensor-Dot Matrix-Color/zh #include <Microduino_Matrix.h> uint8_t Addr[MatrixPix_X][MatrixPix_Y] = { //1x1 {64} //点阵IIC地址 }; Matrix display = Matrix(Addr, TYPE_COLOR); //TYPE_COLOR or TYPE_S2 void setup() { Wire.begin(); display.setBrightness(255); } void loop() { //画空心距形加倒角，起点坐标x,y 宽高w,h 倒角r display.setColor(255, 0, 0); display. drawRFrame(0, 0, 8, 8, 2); //x,y,w,h,r delay(2000); display.clearDisplay(); display.setColor(0, 255, 0); display.drawRFrame(1, 1, 6, 6, 2); //x,y,w,h,r delay(2000); display.clearDisplay(); } 单色点阵：Sensor-Dot Matrix-S2/zh #include <Microduino_Matrix.h> uint8_t Addr[MatrixPix_X][MatrixPix_Y] = { //1x1 {64} //点阵IIC地址 }; Matrix display = Matrix(Addr, TYPE_S2); //TYPE_COLOR or TYPE_S2 void setup() { Wire.begin(); display.setBrightness(255); } void loop() { //画空心距形加倒角，起点坐标x,y 宽高w,h 倒角r display. drawRFrame(0, 0, 8, 8, 2); //x,y,w,h,r delay(2000); display.clearDisplay(); display.drawRFrame(1, 1, 6, 6, 2); //x,y,w,h,r delay(2000); display.clearDisplay(); } 其他 setBrightness() setLed() getHeight() getWidth() clearDisplay() setColor() drawLine() drawBox() drawFrame() drawCircle() drawDisc() print() writeString() drawBMP()
