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
