batch image stretching in idl 1315 1
Started by Deleted User
Hi,
I have a large number of images that are data type 2 and need to be data type 1. I have done this for individual images in ENVI by doing 'Basic Tools' > 'Stretch Data' > select image and then enter the Min and Max as 0.0 and 100.0 and change the data type from 'Integer' to 'Byte'. I am wondering if there is a function or way to do this as a batch script in IDL
Thank you.
