      See 
"https://www.dropbox.com/sh/uwxubmh4lcoxx3n/AABUbehkTYfKd0InpenoyEZXa?dl=0";. 
This contains "CCL-Logo-H2.png" and "CCL-Logo1_6.xcf".  I imported the 
png file, did Image > "Canvas size" > [Height = 251, y = 96] > Resize, 
then saved the result as the xcf file.


      If the dropbox link doesn't work for you, please suggest how I 
can get around this problem.  My initial post had the png file attached, 
but the mailman software stripped it.


      Thanks,
      Spencer
