[gdal-dev] Are those 2 things possible using gdal2tiles?

[Jorge Arévalo]

- Generate JPEG tiles instead of PNG. Tried just replacing the driver's 
name (PNG) with JPEG. Didn't work. Base tiles are generated, but 
overview tiles are not. Getting this error instead: ERROR 1: Buffer too 
small
- Apply a color to nodata value of generated tiles. Tried passing -a 
"200,0,0" to gdal2tiles, but it was ignored.


Log file, with GDAL_DEBUG=On, where you can see the first problem 
(buffer too small):

Modified version of gdal2tiles, to generate xyz caches instead of tms 
ones:

tif tile for testing (same error with other ones):

Many thanks!
