Dane Springmeyer	27fbc4549d	change the method for calculating offsets to pass to GDALRasterIO, as the 'start_x, start_y' implementation added in r1321 was leading to large shifts in 1-banded srtm data without overviews - this new approach works with and without overviews and also with 3 band rbg data. Also added more debug output.	2009-10-12 05:25:36 +00:00
Dane Springmeyer	c808cf62b9	add support for gdal overviews to the Gdal Plugin (use http://www.gdal.org/gdaladdo.html to build overviews) - modified patch from gdalcolors branch from Alberto Valverde (I removed dependence on color/masking code until that support lands in trunk) - addresses #54	2009-09-27 17:23:09 +00:00
