The cursor is used to point at the center of the desired window. Thus SETXWIN (45, 66) will specify a window of 45 X pixels and 66 Y pixels centered on the cursor. There are no input adverbs. @ Output adverbs: BLC @ 0.0 16384.0 Bottom left corner TRC @ 0.0 16384.0 Top right corner PIXXY @ 0.0 16384.0 Map pixel position: center DELTAX @ 0.0 16384.0 X width in pixels DELTAY @ 0.0 16384.0 Y width in pixels ---------------------------------------------------------------- SETXWIN Type: Procedure Use : To set window adverbs BLC and TRC by giving the widths of the window (in pixels) as immediate arguments and by pointing at the center of the window with the TV cursor pressing any button. Arguments: Width in X, width in Y in pixels. i.e. SETXWIN (200, 55) will set a window 200 pixels in X by 55 pixels in Y. Adverbs: There are no input adverbs. The following adverbs have their values changed by the procedure. BLC........Bottom left corner of window TRC........Top right corner of window PIXXY......Map pixel position at center of window. DELTAX.....Width in X pixels DELTAY.....Width in Y pixels ----------------------------------------------------------------
