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

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
Lucio Asnaghi
3805ee0fab + added a "shared" parameter to select if you want to open the dataset in shared mode (causing problems when multiple accesses to the same file)
+ introduced some more code for supporting overviews (still commented out as default, need revision)
