// 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:

  // Draw bitmap with top left corner at x,y with foreground and background colors
