Are proj4 strings case sensitive?












5















Is there any reason that case of characters in Proj4 strings would affect their interpretation? Before parsing a Proj4 string, can I lower case all the characters first?

          Yes, it's case sensitive. Each +parameter=value pair are normally case sensitive.



          For example with the parameter, there are two separate ellipsoid radius parameters R_A and R_a, which have different meanings.



          And an example where the value is case sensitive is on case-sensitive systems (e.g. Linux), where the lowercased +nadgrids=beta2007.gsb fails to find BETA2007.gsb in PROJ_LIB. This value is normally +nadgrids=BETA2007.gsb for consistent operation across different operating systems.

                    ASUS Zenbook UX433/UX333 — Configure Touchpad-embedded numpad on Linux

                    Image
                    0 1 I have an ASUS Zenbook UX433,on which ASUS decided to innovate by embedding a Numpad inside the touchpad (see picture 1). Toggling between classic touchpad mode and numpad (also turns the touchpad LEDs on) can be done through the golden button in the top-right corner of the touchpad. However, on my Manjaro arch Linux config, this behavior does not work by default and I can only use the touchpad, no numpad. Has anyone been able to configure the numpad to work on Linux, or have any idea how this could be achieved? EDIT1: I have had a look at the official Windows drivers for the UX433FA TouchPad, but was not able to make anything of it. I tried installing them on Linux using tools like NDISWrapper, but they do not detect the TouchPad/Numpad hardware, and my understanding of drivers is too limited.
