QGIS » QGIS Application

A really useful enhancement for qgis (and obviously qgis-server)
could be the capability to define an "Acetate Layer".
It is a layer not linked to a datasource, but completely defined by the user.

An acetate layer should allow to define a label with a text or a symbol or an image.

If it is an image it could be addressed by a path on filesystem.
Otherwise if it is a text label, it could be a text with an outline or without.

(a logo for example) addressed by filesystem.

An acetate layer in ist properties should allow to define
the text to draw using a choosed font, a choosed color and a choosed type (bold, regular, italic)
also allow to give the starting coords to some coords defined in the acetate layer properties,
also the starting pixel-coordinates and also the angle (0-360)

please notice, the coordinates are defined as fixed pixel coordinate, instead of a geographic coord.

So for example giving
text= "copyright alfa beta"
and
coords="10,10"
and
angle="90"

the acetate when light-on will draw the text given starting from pixel
10,10 along a virtual line with an angle of 90 degree.

This will allow to have always a copyright watermark (or a copyright image-logo) always in the same position
of the generated map.
