   4 //      Simple example of a button with text over an image
   5 //      Originally from erco's cheat sheet 10/25/2010, permission by author.
   6 //
   7 //      This shows how to include an 'inline' image (.xpm)
   8 //      and have it appear on an Fl_Button. Demonstrates the use of the
   9 //      FL_ALIGN_IMAGE_BACKDROP align() flag (new in FLTK 1.3.0).
  10 //
  11 //      Note that the XPM can just as easily be in an #include file,
  12 //      but to keep the example self contained, the image (a gray scale
  13 //      gradient) is included here.
