def get_part(window_handle: HHandle) -> Tuple[Union[int, float], Union[int, float], Union[int, float], Union[int, float]]

Description

get_partget_partGetPartGetPartget_part returns the upper left and lower right corner of the image part shown in the window. The image part can be changed with the operator set_partset_partSetPartSetPartset_part (Default is the whole image).

Execution Information

• Multithreading type: reentrant (runs in parallel with non-exclusive operators).
• Multithreading scope: global (may be called from any thread).
• Processed without parallelization.
