<h2>DESCRIPTION</h2>
|
||||
|
||||
<i>wximgview</i> is a simple wxWidgets image viewer for 32-bpp BMP images, as
|
||||
can be created with the <em><a href="pngdriver.html">PNG</a></em> and
|
||||
<em><a href="cairodriver.html">cairo</a></em> drivers. The display is
|
||||
continually refreshed.
|
||||
|
||||
<h2>NOTES</h2>
|
||||
|
||||
The display driver must be configure to map the file, with
|
||||
<em>GRASS_RENDER_FILE_MAPPED=TRUE</em>. This ensures that the file will remain
|
||||
a constant size, rather than being truncated whenever it is updated.
|
||||
|
||||
|
||||
<h2>EXAMPLE</h2>
|
||||
|
||||
(bash shell syntax)
|
||||
<div class="code"><pre>
|
||||
export GRASS_RENDER_FILE=map.bmp
|
||||
export GRASS_RENDER_WIDTH=640
|
||||
export GRASS_RENDER_HEIGHT=480
|
||||
export GRASS_RENDER_IMMEDIATE=cairo
|
||||
export GRASS_RENDER_FILE_MAPPED=TRUE
|
||||
export GRASS_RENDER_FILE_READ=TRUE
|
||||
|
||||
d.erase
|
||||
wximgview $GRASS_RENDER_FILE percent=50 &
|
||||
d.rast elevation.dem
|
||||
d.vect roads
|
||||
</pre></div>
