I have several thousand plans in .cal and .GP4 whose colors I need to invert (switch to “positive” mode when they are in “negative”). I know it is possible to do it one by one in softwares like autocad but I am looking for a mass processing method for obvious reasons of saving time.
I created a Python program in order to perform the operation but a priori there are no libraries that allow to easily manipulate the .cal and .GP4 files. I also looked at a solution of parsing the .cal and .GP4 files to find the parameter to modify, but that did not give anything either.
Does anyone have an idea to solve this problem?
