The image information utility imf_info is started as
imf_info [options] file...
It will display information about all named image files, including resolution, number of color components, number of bits per component, gamma factor if available, top-down or bottom-up line ordering, data type, and the image format. There is only one option:
-v
Verbose output prints messages showing what imf_info is doing, and a version banner.
-p
3.1 Plot a simple pixel intensity histogram.
-m
Prints information about multipass sample files.
-l
Prints pyramid layer resolutions for memory-mapped texture files.
-L
Prints more detailed pyramid layer information, including deviations from the expected resolutions. This is useful for map files created with imf_copy -c.
