RE: [Vxl-maintainers] Set View

[Ian S. <ian...@st...>]

If the frame grabber is represented by vil2_image_data object, then the
get_view(..) method can return a new view of the existing buffer.
vil2_memory_image works similarly. It contains some image data, Every time
someone calls get_view(..) on that vil2_memory_image, it returns a new
vil2_image_view that looks at the same underlying data.

Is this sufficient?

Note: We currently use a mil_image_2d (which is a view like vil2_image_view)
to wrap the output buffer of a framegrabber without any problems.

  The idea of  set_view(..) is to be able to use an existing piece of memory
as the data for an image.  This condition arises for example in the case of
a frame-grabber of live video where a buffer is being filled by the camera
feed and designated by the camera driver.
