DESCRIPTION

       ximgview  is  a  simple X11 image viewer for 32-bpp BMP images, as can be created with the
       PNG and cairo drivers. The display is continually refreshed.

NOTES

       The display driver must be configure to map the file, with  GRASS_RENDER_FILE_MAPPED=TRUE.
       This  ensures  that  the  file  will  remain  a constant size, rather than being truncated
       whenever it is updated.

EXAMPLE

       (bash shell syntax)
       export GRASS_RENDER_FILE=map.bmp
       export GRASS_RENDER_WIDTH=640
       export GRASS_RENDER_HEIGHT=480
       export GRASS_RENDER_IMMEDIATE=PNG
       export GRASS_RENDER_FILE_MAPPED=TRUE
       export GRASS_RENDER_FILE_READ=TRUE
       d.erase
       ximgview $GRASS_RENDER_FILE percent=50 &
       d.rast elevation.dem
       d.vect roads
