Detailed Description
Loader for VIFF files, i.e., 1-banded Khoros 1.0 images.
This supports char, short, int, float and double pixel cell types. Adapted from the version by Reinhard Koch, Nov. 19, 1996.

◆ make_blocked_output_image()

Construct a blocked output image resource.
Returns a null resource unless the format supports blocking
Reimplemented in vil_tiff_file_format.
Definition at line 75 of file vil_file_format.h.
◆ make_input_image()
|
overridevirtual |
Attempt to make a generic_image which will read from vil_stream vs.
Reads enough of vs to determine if it's this format, and if not, returns 0. If it is, returns a subclass of vil_image_resource on which get_section may be applied.
Implements vil_file_format.
Definition at line 45 of file vil_viff.cxx.
◆ make_input_pyramid_image()
|
inlinevirtualinherited |
Read a pyramid resource from a list of image files in a directory.
... or from an image file_format that supports multiple images per file.
Reimplemented in vil_tiff_file_format, and vil_pyramid_image_list_format.

◆ make_output_image() [2/2]
|
pure virtualinherited |
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]
|
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.
Reimplemented in vil_tiff_file_format.

E.g. "pnm", "jpeg", etc.
