This question already has an answer here:
I am using Normalize difference vegetation index (NDVI) derived from the landsat satellite band 3 and band 4 that have float values ranges from -1.0 to 1.0. I want to see the attribute table that is not possible in QGIS. I tried following expression in raster calculator of qgis but it did not work:
Int("float_raster" * 100)
the reason to multiply with 100 is to preserved the 2 digits at right level in attribute table that can be seen by again dividing by 100 in attribute table.
How can i scale see the better contrast in colour palette using qgis 2.40
