Yes, look at line 61. Simply use the Colors[] array property.

The code I suggested was not meant as a complete implementation for you,
but as an example of how to use the fpImage and FPReadPNG units. Like I
said, once the PNG file is loaded, use the Colors[] array property to
access the pixel data.
