set_window_extents — Modify position and size of a window.
set_window_extents( : : WindowHandle, Row, Column, Width, Height : )
set_window_extents positions the upper left corner of the
output window at (Row,Column) and changes the size of the
window to Width and Height at the same time. Negative
values for Width and Height 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.
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.
WindowHandle (input_control) window → (handle)
Window handle.
Row (input_control) rectangle.origin.y → (integer)
Row index of upper left corner in target position.
Default value: 0
Typical range of values:
Row
(lin)
Minimum increment: 1

Column (input_control) rectangle.origin.x → (integer)
Column index of upper left corner in target position.
Default value: 0
Typical range of values:
Column
(lin)
Minimum increment: 1
Recommended increment: 1
Width (input_control) rectangle.extent.x → (integer)
Width of the window.
Default value: 512
Typical range of values:
Width
(lin)
Minimum increment: 1
Recommended increment: 1
Height (input_control) rectangle.extent.y → (integer)
Height of the window.
Default value: 512
Typical range of values:
Height
(lin)

Recommended increment: 1
If the window is valid and the parameters are correct
set_window_extents returns 2 (H_MSG_TRUE).
