No inputs Optional immediate argument gives width of wedge in pixels (default 16). If argument < 0, program uses TV cursor to determine where to put wedge (default below bottom or above top of image). Uses TV cursor to select the image with which the wedge is associated (if needed). ---------------------------------------------------------------- TVWEDGE Type: Verb Use: To load a linear wedge into a TV memory plane using the same transfer function and clipping used in loading the associated image. TVWEDGE constructs the wedge with intensities from the PIXRANGE(1) to PIXRANGE(2) used in loading the image to the TV. If there is more than one image on the TV, the routine asks the user to point out the image with which the wedge is to be associated. There is an optional imediate argument: IMPWEDGE (n) If n is missing, use n=16, where n is the width of the wedge in pixels. If n<0 use abs(n) as the width of the wedge and ask the user to indicate where to draw the wedge. The default locations of the wedge are: (a) If there is only one image visible, far enough below or above the image to allow for complete labeling, (b) just below the image (if it will fit), (c) above the image (if it will fit), and (d) overlaying the bottom rows of the image. Adverbs: None ----------------------------------------------------------------
