#include <vil3d_image_view.h>
Inheritance diagram for vil3d_image_view< T >:
Views nplanes() planes of data each of size ni() x nj() x nk(). The (i,j,k) element of the p'th plane is given by im.origin_ptr()[i*im.istep() + j*im.jstep()+ k*im.kstep() + p*im.planestep] The actual image data is either allocated by the class (using set_size), in which case it is deleted only when it has no views observing it, or is allocated outside (and is not deleted on destruction). This allows external images to be accessed without a deep copy.
Note that copying one vil3d_image_view<T> to another takes a shallow copy by default - it copies the view, not the raw image data. Use the explicit deep_copy() call to take a deep copy.

Set this view to look at someone else's memory data.
If the data goes out of scope then this view could be invalid, and there's no way of knowing until it's too late -- so take care!
Note that though top_left is passed in as const, the data may be manipulated through the view.

| bool vil3d_image_view< T >::operator== | ( | const vil3d_image_view< T > & | other | ) | const |
True if they share same view of same image data.
This does not do a deep equality on image data. If the images point to different image data objects that contain identical images, then the result will still be false.

Provides an ordering.
Useful for ordered containers. There is no guaranteed meaning to the less than operator, except that (a<b && b<a) is false and !(a<b) && !(b<a) is equivalent to a==b
