sudo apt install imagemagick

from fltk import *

#xbm is monochrome but xpm has color :)
#use imagemagick software to convert png to xpm
# convert -resize 60x43 smilycat.png smilycat.xpm
#then copy/paste the xpm data to your python source code as a list
#edit the image data as shown below

'''
Required edits of xpm data in python source code file.

1) Remove the following 3 lines from the top of the data
/* XPM */
static char *smilycat[] = {
/* columns rows colors chars-per-pixel */

2) Remove the following line from the middle of the data
/* pixels */

3) Replace the following line from the end of the data
};
with a list close bracket
]

4) Insert a list variable line at top of data
for example: smilycat_bits=[
'''
