Hi List, Is there a way to control the block size of overviews and inspect that block size from gdalinfo ? I have a raster with 256x256 block size. Band 1 Block=256x256 Type=Byte, ColorInterp=Red Band 2 Block=256x256 Type=Byte, ColorInterp=Green Band 3 Block=256x256 Type=Byte, ColorInterp=Blue
I'm trying to feed the images to a program that seemingly supports Tiffs with internal overview of the same block size than the image. I've tried >gdaladdo --config BLOCKXSIZE 256 --config BLOCKYSIZE 256 image.tif 2 4 8 16 32 gdalinfo: Band 1 Block=256x256 Type=Byte, ColorInterp=Red Overviews: 8655x5655, 4328x2828, 2164x1414, 1082x707, 541x354 Band 2 Block=256x256 Type=Byte, ColorInterp=Green Overviews: 8655x5655, 4328x2828, 2164x1414, 1082x707, 541x354 Band 3 Block=256x256 Type=Byte, ColorInterp=Blue Overviews: 8655x5655, 4328x2828, 2164x1414, 1082x707, 541x354 But I couldn't find a way to inspect the overview block size to confirm they are 256x256 since I get the same results if I set BLOCKSIZE to 128. I suspect these options are ignored in gdaladdo. Any way I can 1) control the overview block size and 2) inspect the block size ? Thanks for your help, Etienne
