Get handle to current figure containing image
hfig = imgcf
hfig = imgcf returns the
handle of the current figure that contains an image. The figure may
be a regular figure window that contains at least one image or an
Image Tool window.
If none of the figures currently open contains an image,
a new figure.
imgcf can be useful in getting the handle
to the Image Tool figure window. Because the Image Tool turns graphics
object handle visibility off, you cannot retrieve a handle to the
tool figure using
imtool rice.png cmap = copper(256); set(imgcf,'Colormap',cmap)
