.SH DESCRIPTION
\fIximgview\fR is a simple X11 image viewer for 32\-bpp BMP images, as
can be created with the \fIPNG\fR and
\fIcairo\fR drivers. The display is
continually refreshed.
.SH NOTES
The display driver must be configure to map the file, with
\fIGRASS_RENDER_FILE_MAPPED=TRUE\fR. This ensures that the file will remain
a constant size, rather than being truncated whenever it is updated.
