Description

copy_rectanglecopy_rectangleCopyRectangleCopyRectangleCopyRectanglecopy_rectangle copies all pixels from the window WindowHandleSourceWindowHandleSourceWindowHandleSourceWindowHandleSourcewindowHandleSourcewindow_handle_source in the window WindowHandleDestinationWindowHandleDestinationWindowHandleDestinationWindowHandleDestinationwindowHandleDestinationwindow_handle_destination. It copies pixels which reside inside a rectangle which is specified by parameters Row1Row1Row1Row1row1row_1, Column1Column1Column1Column1column1column_1, Row2Row2Row2Row2row2row_2 and Column2Column2Column2Column2column2column_2. The target position is specified through the upper left corner of the rectangle (DestRowDestRowDestRowDestRowdestRowdest_row, DestColumnDestColumnDestColumnDestColumndestColumndest_column).

If you want to move more than one rectangle, you may pass them at once (in form of the tuple mode).

You may use copy_rectanglecopy_rectangleCopyRectangleCopyRectangleCopyRectanglecopy_rectangle to copy edited graphics from an “invisible” window in a visible window. Therefore a window with the option 'buffer' is opened. The graphics is then displayed in this window and is copied in a visible window afterwards. The advantage of this strategy is, that copy_rectanglecopy_rectangleCopyRectangleCopyRectangleCopyRectanglecopy_rectangle is much more rapid than output operators as, e.g., disp_channeldisp_channelDispChannelDispChannelDispChanneldisp_channel. This means a particular advantage while using demo programs. You could even realize short “clips”: you have to create for every image of a sequence a window of a 'buffer' type and pass the data into it. Output is the image sequence whereat all buffers are copied one after another in a visible window.

Attention

Both windows have to reside on the same display.
