iconvert - copy images with format conversions and other alterations
iconvert [options] inputfile outputfile iconvert [options] --inplace files...
The iconvert program will read an image (from any file format for which an ImageInput plugin can be found) and then write the image to a new file (in any format for which an ImageOutput plugin can be found). In the process, iconvert can optionally change the file format or data format (for example, converting floating-point data to 8-bit integers), apply gamma correction, switch between tiled and scanline orientation, or alter or add certain metadata to the image. The iconvert utility is invoked as follows: iconvert [options] input output Where input and output name the input image and desired output filename. The image files may be of any format recognized by OpenImageIO (i.e., for which ImageInput plugins are available). The file format of the output image will be inferred from the file extension of the output filename (e.g., "foo.tif" will write a TIFF file). Alternately, any number of files may be specified as follows: iconvert [options] --inplace file1 file2... When the --inplace option is used, any number of file names >= 1 may be specified, and the image conversion commands are applied to each file in turn, with the output being saved under the original file name. This is useful for applying the same conversion to many files, or simply if you want to replace the input with the output rather than create a new file with a different name. For a complete description, see /usr/share/doc/openimageio-doc/openimageio.pdf.gz.
