If it's very big, it might make a disk image, with a temporary name in which case "prototype" will be consulted about issues such as file format etc. If you want more control over the exact disk format, use one of the routines with more than 4 arguments.
Modifications
16 Feb 2000 AWF - Initial version.
25 Sep 2002 Ian Scott - convert to vil.
30 Mar 2007 Peter Vanroose- Removed deprecated vil_new_image_view_j_i_plane

Construct a pyramid image resource from a base image.
All levels are stored in the same resource file. Each level has the same scale ratio (0.5) to the preceeding level. Level 0 is the original base image. The resource is returned open for reading. The temporary directory is for storing intermediate image resources during the construction of the pyramid. Files are be removed from the directory after completion. If temp_dir is 0 then the intermediate resources are created in memory.

Construct a new pyramid image resource from a base image.
The result is a directory containing separate images for each pyramid level. Each level has the same scale ratio (0.5) to the preceeding level and is created using level_file_format. Level 0 is the original base image. If copy_base is false, then Level 0 is already present in the directory and is used without modification. Each pyramid file in the directory is named filename + "level_index", e.g. R0, R1, ... Rn.

Make a new pyramid image resource for writing.
Any number of pyramid layers can be inserted and with any scale. Image resources that duplicate existing scales are not inserted.
