+/* 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
