Hey Kevin,
Thanks for reverting.
I know about the "screencapture" function and the parameters available.
But, how would I take the user input, as in, that is just command-line, as soon
as I execute the program, it will take whatever kind of parameter is passed
under screencapture.
I want that, in the same program, if the user presses Shift+Command+3, whole
screenshot should be taken.
When, Shift + Command + 4 is pressed, a particular frame should be displayed to
select the area / region.
Also, I want to create my own command : Shift + Command + 5 ==> this is
specially for web browser, whenever I press this key on any of the web-page, the
whole web page should be grabbed along with its snapshot, and snapshot's filename
should be web-page's url which I am currently on.
Also, this process should be executing at the backend, so that, whenever these
keys are pressed, it overrides the system's functionality and uses mine.
There are no simple answers to these questions.
With Tkinter, it's possible to code a basic UI and bind combinations of
specific keys to trigger specific callbacks, which can fire specific
sequences of arguments to the screencapture CLI tool. That's the quick
and dirty way. I'm not going to write this code for you. Look at
TkDocs.com and effbot's site for an introduction to Tkinter.
If you are not looking for a GUI app to do this, but some sort of
system-level daemon, that requires a lower level of coding. You'll need
to look at such system frameworks as CoreGraphics and Cocoa to find the
API's you need. PyObjC (Python binding to Cocoa) can probably be helpful
here. Frankly, I'm not sure Python is the best tool here, but if you go
this route, you want a Python API that hews as closely to the
system-level calls as possible, and PyObjC will likely be your best path
here.
