+.B xyza f
+Unscaled CIE XYZ with unscaled alpha channel, in the

+as a single-precision floating-point number using the
+local machines endianness.
+.TP
+.B xyza !f
+Unscaled CIE XYZ with unscaled alpha channel, in the
+order, X, Y, Z, alpha. Each subpixel value is stored
+as a double-precision floating-point number using the
+local machines endianness. This is the default format
+in other commands.
