+# WTI_PUTCOMPLEX -- Output pixels to a text file in complex floating format.
+# Pixels are output in storage order for images of any dimension (leftmost
+# subscript varying fastest).  We do not bother to implement a different
+# datapath for each image pixel datatype because the execution time is
+# entirely dominated by the binary to character conversion, and because we
+# need type complex pixels for XTOC anyhow.
