Symbol layer
model:
The symbol layers may have the
following optional fields:
- a real number field to store
the symbol rotation (degree
counterclockwise where zero = horizontal to the right)
- a real number field to store
the symbol scale
The symbol layer can be
defined with a style set as follows:
- If you decide to handle the
rotation or scale of symbols then the <Style>-<Single
Symbol> option and <Style>-<map units> option must
be enabled
- The rotation could be read by
a real number field that stores the symbol rotation through the
formula "360-<field that stores the rotation>"
(degree counterclockwise where zero =
horizontal to the right, <Style>-<Advanced> option "rotation field
name"-<Espressione>,
if set than the INSERT command will ask for
it)
- The scale can be read by a
real number field that stores the scale of the symbol
(<Style>-<Advanced>-<Size scale field>-“
field that stores the scale” and <Style>-< Advanced
>-<Size scale field >-<Scale diameter>,
if set than the INSERT command will ask for
it)
