brighten
Brighten or darken colormapbrighten(beta) brighten(h,beta) newmap = brighten(beta) newmap = brighten(cmap,beta)
brighten
increases or decreases the color intensities in a colormap. The modified colormap is brighter if 0 < beta < 1
and darker if -1 < beta < 0
.
brighten(beta)
replaces the current colormap with a brighter or darker colormap of essentially the same colors. brighten(beta)
, followed by brighten(-beta)
, where beta < 1
, restores the original map.
brighten(h,beta)
brightens all objects that are children of the Figure having the handle h
.
newmap = brighten(beta)
returns a brighter or darker version of the current colormap without changing the display.
newmap = brighten(cmap,beta)
returns a brighter or darker version of the colormap cmap
without changing the display.
Brighten then darken the current colormap:
beta = .5; brighten(beta); beta = --.5; brighten(beta);The values in the colormap are raised to the power of gamma, where gamma is
brighten
has no effect on graphics objects defined with true color.
