No adverbs ---------------------------------------------------------------- CURVALUE Type: Verb Use: To perform an interactive display of the pixel locations and values of those images visible on the TV. The X and Y pixel coordinates, the pixel value, and the units of the pixel value are displayed in TV graphics channels 2 and 8 at the upper left hand corner of the display. The cursor position determines which pixel is shown. Button D causes the verb to exit. The pixel values are read from disk, if possible, to preserve accuracy and dynamic range. When the images were loaded by another computer or were temporary images (e.g., IMAGR residuals), the pixel values are read from the TV and suffer from limited accuracy and clipping Adverbs: none ----------------------------------------------------------------
