Advanced Features of SAOImageDS9 William Joye What is SAOImageDS9? SAOImageDS9 is NOT PhotoShop (or Gimp) SAOImageDS9 allows the user to MAP from a pixel single numeric value to a pixel RGB triplet Pixel (Floating point) > SAOImageDS9 > Pixel (RGB) The output of SAOImageDS9 is an RGB image which is the input for Photoshop or GIMP
Advanced Features of SAOImageDS9 William Joye What is SAOImageDS9? SAOImageDS9 allows the user to MAP from a single numeric value to a RGB triplet depending upon: Scale Distribution (linear, log, histogram) Region of Distribution (low and high clip values) Color Scale (grey, rainbow, heat, cool) Contrast and Bias (redistribution of colors)
