DESCRIPTION

39       ximgview is a simple X11 image viewer for 32-bpp BMP images, as can  be
40       created  with  the  PNG  and  cairo drivers. The display is continually
41       refreshed.
42

NOTES

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

EXAMPLE

49       (bash shell syntax)
50       export GRASS_RENDER_FILE=map.bmp
51       export GRASS_RENDER_WIDTH=640
52       export GRASS_RENDER_HEIGHT=480
53       export GRASS_RENDER_IMMEDIATE=PNG
54       export GRASS_RENDER_FILE_MAPPED=TRUE
55       export GRASS_RENDER_FILE_READ=TRUE
56       d.erase
57       ximgview $GRASS_RENDER_FILE percent=50 &
58       d.rast elevation.dem
