iinfo(1) print information about images


iinfo [options] files...


The iinfo utility is invoked as follows:

iinfo [options] filename...

Where filename (and any following strings) names the image file(s) whose information should be printed. The image files may be of any format recognized by OpenImageIO (i.e., for which ImageInput plugins are available).

In its most basic usage, it simply prints the resolution, number of channels, pixel data type, and file format type of each of the files listed:

$ iinfo img_6019m.jpg grid.tif lenna.png
img_6019m.jpg : 1024 x  683, 3 channel, uint8 jpeg
grid.tif      :  512 x  512, 3 channel, uint8 tiff
lenna.png     :  120 x  120, 4 channel, uint8 png

For a complete description, see /usr/share/doc/openimageio-doc/openimageio.pdf.gz.
