Construct a pyramid image resource from a base image.
Construct pyramid image files in the directory.
Each level has the same scale ratio (0.5) to the preceding level. 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.
Each level has the same scale ratio (0.5) to the preceding level. Level 0 is the original base image.

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 preceding 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.
