Hello
I am trying to apply a contrast stretch to an image (linear). The r.rescale
facility simply changes the category values to 1-255 without actually
applying the stretch. Also, the image is an export from Erdas Imagine and
the disply is different such that the display colors are disimilar. I get
the impression that the color file may have something to do with this. How
do I make sure the color remains the same between the 2 software?
Hi,
You can check the R-G-B combinations for the grass
image colors in file "image_name" in the directory
$DATABASE/$LOCATION/$MAPSET/colr:
the first field is cat number
the other three are r-g-b
--alex
