The relevant part of the Adafruit library is the write function implementation:

adafruit/Adafruit-GFX-Library/blob/master/Adafruit_GFX.cpp#L809-L858


      
              @param    y   Top left corner y coordinate
              @param    bitmap  byte array with monochrome bitmap
              @param    w   Width of bitmap in pixels
              @param    h   Height of bitmap in pixels
              @param    color 16-bit 5-6-5 Color to draw pixels with
              @param    bg 16-bit 5-6-5 Color to draw background with
          */
          /**************************************************************************/
          void Adafruit_GFX::drawBitmap(int16_t x, int16_t y, uint8_t *bitmap, int16_t w,
                                        int16_t h, uint16_t color, uint16_t bg) {
          
          
  int16_t byteWidth = (w + 7) / 8; // Bitmap scanline pad = whole byte
            uint8_t b = 0;
          
          
  startWrite();
            for (int16_t j = 0; j < h; j++, y++) {
              for (int16_t i = 0; i < w; i++) {
                if (i & 7)
                  b <<= 1;
                else

Then you can find println in the Arduino core library for your board. For Arduino AVR Boards that is here:
