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 re-
freshed.
NOTES
The display driver must be configure to map the file, with GRASS_REN-
DER_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
