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
