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
