Hi Steven
I'm very happy that you work on mapcomposer troubles!
I try to answer to yor request:

We need a continuos (ex. for dtm raster) or category value legend (best if
it is possible choise it) about all the raster load in the map canvas, Ask
me if you need same other information.

This bug is quite limitant, I hope it is'nt a hard work!

I'm going to test it!

Ok

Here I'd like to show other map composer bugs:
- about labels: https://svn.qgis.org/trac/ticket/754
- about move objects in mapcomposer: https://svn.qgis.org/trac/ticket/758

- about pdf output: https://svn.qgis.org/trac/ticket/823

Hope this helps.
Many thanks for your work!
