描述
clear_rectangleclear_rectangleClearRectangleClearRectangleClearRectangleclear_rectangle deletes all entries in the rectangle which
is defined through the upper left corner
(Row1Row1Row1Row1row1row_1,Column1Column1Column1Column1column1column_1) and the lower right corner
(Row2Row2Row2Row2row2row_2,Column2Column2Column2Column2column2column_2). Deletion means that the
specified rectangle is set to the background color (see
open_windowopen_windowOpenWindowOpenWindowOpenWindowopen_window).
If you want to delete more than one rectangle, you may pass several
rectangles, i.e., the parameters Row1Row1Row1Row1row1row_1, Column1Column1Column1Column1column1column_1,
Row2Row2Row2Row2row2row_2 and Column2Column2Column2Column2column2column_2 are tuples.
运行信息
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
