.SH DESCRIPTION
The \fIblitspin\fP program repeatedly rotates a bitmap by 90 degrees by
using logical operations: the bitmap is divided into quadrants, and the
.B \-mono
If on a color display, pretend we're on a monochrome display.
.TP 8
-.B \-bitmap bitmap-name
-The bitmap to rotate. It need not be square: it will be padded with
-the background color. Default is \fIxlogo64\fP, but \fIescherknot\fP
-is also nice. You really need to run this on a bigger bitmap than
-those shipped with the X distribution to do it justice.
+.B \-install
+Install a private colormap for the window.
+.TP 8
+.B \-visual \fIvisual\fP
+Specify which visual to use. Legal values are the name of a visual class,
+or the id number (decimal or hex) of a specific visual.
+.TP 8
+.B \-bitmap \fIfilename\fP
+The file name of a bitmap to rotate. It need not be square: it
+will be padded with the background color. If unspecified or the
+string \fI(default)\fP, a builtin bitmap is used.
-The \fB*bitmapFilePath\fP resource will be searched if the bitmap name
-is not a fully-qualified pathname.
-.SH ENVIRONMENT
+If support for the \fIXPM\fP library was enabled at compile-time,
+the specified file may be in \fIXPM\fP format as well as \fIXBM\fP, and
+thus may be a color image.
+
+The \fB*bitmapFilePath\fP resource will be searched if the bitmap
+name is not a fully-qualified pathname.
