set_window_extents( : : WindowHandle, Row, Column, Width, Height : )

描述

set_window_extentsset_window_extentsSetWindowExtentsSetWindowExtentsSetWindowExtentsset_window_extents positions the upper left corner of the output window at (RowRowRowRowrowrow,ColumnColumnColumnColumncolumncolumn) and changes the size of the window to WidthWidthWidthWidthwidthwidth and HeightHeightHeightHeightheightheight at the same time. Negative values for WidthWidthWidthWidthwidthwidth and HeightHeightHeightHeightheightheight are ignored.

Adapting the size of the window to the size of the image part to be displayed will prevent slowing down the display due to necessary interpolations. Thus, the window preferably has the same size as the image part to be displayed, or otherwise half its size, quarter its size, etc.

注意

Modifying the size of the window does not automatically redraw the window contents. This has to be done by the program by redisplaying the desired data.
