Read a pyramid resource. Image list files are stored in directory.
Load a pyramid image. The path should correspond to a directory.
If not, return a null resource.

Make a "generic_image" on which put_section may be applied.
The stream vs is assumed to be open for writing, as an image header may be written to it immediately. The width/height etc are explicitly specified, so that file_format implementors know what they need to do...
Implemented in vil_tiff_file_format, vil_nitf2_file_format, vil_ras_file_format, vil_jpeg_file_format, vil_pnm_file_format, vil_j2k_file_format, vil_png_file_format, and vil_sgi_file_format.
◆ make_pyramid_image_from_base() [1/2]

overridevirtual |
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.

◆ make_pyramid_image_from_base() [2/2]

inlinevirtualinherited |
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.
