hello sir
I have a LANDSAT image imported in my mapset using r.in.gdal. I used
r.composite to combine the rgb files. After all these, now if I wants to get
the pixel value on click of a mouse on the raster map. Is it possible for me
to somehow get the pixel value (that is red, blue and green color values
which should lie within 0-255 range) on click. I need some help.
Yes, *before* you combine the bands. If you select one band
and use the query button in the GUI interface, you'll get the
pixel value of that band at the click location.
Thanks in advance..
