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_PNG_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_PNGFILE=map.bmp
export GRASS_WIDTH=640
export GRASS_HEIGHT=480
export GRASS_RENDER_IMMEDIATE=PNG
export GRASS_PNG_MAPPED=TRUE
export GRASS_PNG_READ=TRUE

d.erase
ximgview $GRASS_PNGFILE percent=50 &
d.rast elevation.dem
d.vect roads
