// Example sketch to demonstrate the drawing of X BitMap (XBM)
// format image onto the display.

// Information on the X BitMap (XBM) format can be found here:
// https://en.wikipedia.org/wiki/X_BitMap

// This example is part of the TFT_eSPI library:

  // =========
  // Random x and y coordinates

  // =========
  // New random x and y coordinates

  y = random(tft.height() - logoHeight);

  // Draw bitmap with top left corner at x,y with foreground and background colors
  // Bits set to 1 plot as the defined fg color, bits set to 0 are plotted as bg color
