Hi Brent,<br>
<br>
thanks for your advice. I will try both, (a) manipulating and using
the world file of the image I am saving outside the map composer and
(b) the geo-referencing of the maps with the geo-ref. tools in QGIS.<br>
Since I am producing a series of 4-6 different thematic maps on each
area of interest, I was hoping to find a more efficient way to
geo-reference the maps, but on the other hand, because the maps
series is always using the identical map template, a commonly used
world file might be a feasible way to solve the problem .....<br>
I´ll find it out.<br>
<br>
Regards,<br>
Markus<br>

<br>
If you choose "File -> Save as Image", then save as a
PNG, for example, the on screen image is saved, along with
the world file allowing it to be reused.<br>
<br>
Note that the file suffix pngw will be used, not wld or
pgw for the world file.<br>
<br>
However, I'm not aware of this being directly supported
from the map composer, but there are a couple of ways of
doing this that might work for you.<br>
<br>
You could use the georeferencing tool to generate a world
file from a saved map composer image, but this can be a
bit fiddly, although a useful exercise for students in its
own right.. <br>
<br>
You could also use an image processing tool to convert a
composer image to the same pixel geometry as a saved map
window, in which case the world file would also apply to
it, or perhaps double the x & y pixel counts (for
better resolution) and halve 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>

<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>
