the pixel offset values in the world file. For this to work you'd need to have all the map composer elements overlaying the actual map (if this is possible), rather than outside the map, and therefore extending the apparent image extent.<br><br>Cheers<br><br>Brent Wood<br><br>--- On <b>Sun, 8/14/11, Markus Weidenbach <i><landconsult@freenet.de></i></b> wrote:<br><blockquote style="border-left: 2px solid rgb(16, 16, 255); margin-left: 5px; padding-left: 5px;"><br>From: Markus Weidenbach <landconsult@freenet.de><br>Subject: [Qgis-user] World File for map compositions<br>To: qgis-user@lists.osgeo.org<br>Date: Sunday, August 14, 2011, 6:57 AM<br><br><div id="yiv970103327">
Dear list,<br>
<br>
is there a way to save a world file together with an image of a
completely designed map in the map composer?<br>
The idea is to provide less experienced GIS users with a
geo-referenced raster image (or pdf) of a complex map composition
including an explaining legend, scale bar, north arrow and
pre-defined layers in a specific order and layout. Such an image
could easily be used by GIS beginners to visualize complex thematic
issues and even add further layers or do some area/length
measurements.<br>
Any hints and ideas how this could be managed are welcome.<br>
<br>
Regards,<br>
<br>
Markus<br>
