obout Capture

Supposing you are talking about the Java level API, ...

at 1: ... then yes, Screen.capture() returns a ScreenImage object, that in turn has some methods to save the content and to access the BufferedImage directly.

at 2: capture() silently captures the given region, whereas userCapture() is the interactive capture feature, that allows the user, to define the region to be captured by dragging over the screen.

see:

1. my code:
from sikuli.Sikuli import *
scr = Screen()
bound = scr.getBounds()
# create .png screenshot file in %TEMP% dir
scr_name = scr.capture(x, y, w or bound.width, h or bound.height)

 returned the path to the file before, now it returns an ScreenImage

i noticed, you deprecated class Screen.py. is it True?

2 Thank you

Sorry fo my bad english))))

in Sikuli(X) up to version 1.x it is not recommended to use the Java notation like scr.capture(), since internally all non-dotted methods are automatically bound to the object SCREEN, which is initialized as Screen(0).

So for version 1.1.x (recommended in any case) this works as expected:
scr_name = capture(...whatever allowed...)

so your snippet should read:
from sikuli import * # only needed in imported files or with plain Jython
# create .png screenshot file in %TEMP% dir
scr_name = capture(SCREEN)

Thank you
