/* IM 3 sample that copies an image from one file to another.
It is good to test the file formats read and write.
If the destiny does not supports the input image it aborts and returns an error.
Needs "im.lib".
Usage: im_copy <input_file_name> <output_file_name> [<output_format> [<output_compression]]
Example: im_copy test.tif test_proc.tif
