Certainly. And I again want to thank you for your help. The files totaled 13MB so I've put them on the web at http://bigsurtrailmap.net/TEMP/ I will expect to delete them at some time but not for at least a month.
The "transparent" tif was created by drawing lines on a transparent canvas of specified size using ImageMagic convert. The "depth8polygons" tif was created similarly with "-depth 8" flag added and partial-opacity polygons also drawn (outlined+filled with magenta, but they display in gray). Both were processed with "gdal2tiles.py -z 14 --resampling=average ...vrt" The "transparent" file gives bad results, the "depth8polygons" one displays as expected (except for the polygons being gray). Besides the associated .vrt files I've added the .prf & .tfw files used to create them and the gdal2tiles.py I used. If I can help further let me know, but unfortunately my Python coding skills are non-existent.
