Hi, I would like to change a tif file from datatype: Byte to DataType: I32, but
when I open the original file and the new I32 file in QGis or in ArcMap there
is a huge difference in the colors of the 2 files. How can I do this conversion
without the color change?
I'v tried this:
gdal_translate.exe -if GTiff -of GTiff -ot Int32 -r cubicspline -co BIGTIFF=NO
-co PIXELTYPE=DEFAULT -co GEOTIFF_VERSION=AUTO 34SCJ_8bit.tif 34SCJ_I32.tif
This is the info I can get from the orig file:
Driver: GTiff/GeoTIFF
