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
