How to use tk in hvision library?
In our workstation lab (R219), all the workstations, including
linux and solaris operation systems, had already installed the
hvision library and have `tk` to be use.
You can read our Course Lecture Notes Chapter 1.
In the end of that chapter, there are some simple tutorials of tk.
Here TA lists some useful "Quick Guides":
(please login our workstation)
tk> list command (and you can see some useful commands)
tk> read image: src.im dest.im (src.im is in disk, and dest.im in memory)
(if you are not sure how many parameter should be given, just type
the command name, then you can interactively input all parameters)
tk> view image: dest.im
tk> help some_command_here (see the help pages of commands)
tk> quit ("quit" to leave tk and back to your unix shell)
When I type `tk` in unix shell, there are error messages like below,
Xlib: connection to "jan.csie.ntu.edu.tw:0.0" refused by server
Xlib: Client is not authorized to connect to Server
