[Bug 729260] Re: setROI updates the constant variable SCREEN

 

SCREEN is a CONSTANT REFERENCE a Screen object Screen(0) and not its
contents (it is a convenience).

So per definition setROI() changes the region of interest of the SCREEN
object.

If you do not want this, you have to qualify your Screen/Region methods
with the Screen/Region object or use with:

Title:
  setROI updates SCREEN --- it is not a constant content

Status in Sikuli:
  Invalid

Bug description:
  Calling setROI(smaller_region) changes the global variable SCREEN,
  which I assume is meant to be constant.  The __str__ function of
  SCREEN also isn't updated to reflect the change.

  print SCREEN
  print SCREEN.getW()
  setROI(Region(0,0,100,100)
  print SCREEN
  print SCREEN.getW()
  setROI(SCREEN)

  This prints out the following, and at the end the ROI is not updated to the entire screen:
  Screen(0)[0,0 1440x900] E:Y, T:3.0 
  1440 
  Screen(0)[0,0 1440x900] E:Y, T:3.0 
  100

  We can save the original parameters of SCREEN to a variable to get
  around this, but it took a while to figure out what was happening.
