+# ImageMagick ptest:
+# We ceate an BASERGB file for our usage using "magick"
+# We convert this RGB file to BASEPNG
+# Using BASEPNG we recreate RGB named REGENERATEDRGB
+#
+# BASERGB to BASEPNG to REGENERATEDRGB
+# - Then compare  BASERGB with REGENERATEDRGB
+#
+# 0) The convert command is deprecated in IMv7
+#    used "magick" instead of "convert"
+# 1) We are checking if the binaries are present in RFS or not
+# 2) We Created an RBG of size : WIDTH x HEIGHT pixels
+# 3) Return value is captured after every major actio to capture the status
+# 4) cmp -s is used to compare binary byte by byte data and
+#    capture only exit status
+# 5) Important parametsrs used are :
+#    -depth                     : How many bits for each colour pixel
+#    -alpha off                 : Don't consider transparency
+#    -define png:color-type=2   : Make PNG work with truecolour RGB
+#    -strip                     : Remove all non-pixel metadata og PNG
+#                                 so file is reproducible
