Dane Springmeyer	5e16e04b28	gdal: ensure scaling is available within raster_symbolizer at necessary scales by avoiding pre-scaling in gdal RasterIO	2009-10-22 16:58:03 +00:00
Dane Springmeyer	eee88806b8	remove testing debug line	2009-10-12 05:27:16 +00:00
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	7785461d1f	remove testing debug line from gdal plugin	2009-10-11 16:12:36 +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
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)	2009-05-15 10:31:49 +00:00
