The short story:
----------------
Is it possible to bind a CLASS's SYMBOL object to an attribute (i.e
store the
symbol name as a attribute of a feature)? And the LABEL objects FONT
name?
The Long Story:
---------------
I've been working with the yet-to-be-released Feature Editor in Geomoose
v2. It
allows the user to digitize features (points, lines, and polygons) and
assign
attributes, then stores them in PostGIS.
I want to allow simple styling and don't want to have a map file the
size of
"War and Peace", so I thought I would use the attribute/item/column
binding
abilities of Mapserver's CLASS and LABEL objects.
To that end, one of the columns the feature table will be "style name"
(or maybe
"feature class"), which I'll use to join to a style table (with COLOR,
WIDTH,
etc columns) to get the feature rendered in a simple style.
After a quick review of Mapserver's doc, most of the most important
objects can
be bound to attributes, with two exceptions, SYMBOL 'name' and FONT
'name':
CLASS
STYLE
ANGLE [angle]
COLOR [color] #R G B
OUTLINECOLOR [olcolor] #R G B
SIZE [size]
WIDTH [width] # v5.2
SYMBOL 'name' # in SYMBOLSET
END #STYLE
TEXT ([label])
LABEL
ANGLE [label_angle]
COLOR [label_color]
OUTLINECOLOR [label_olcolor]
PRIORITY [label_priority]
SIZE [label_size]
FONT 'name' # in FONTSET
END #LABEL
END # CLASS
How difficult would it be to have attribute binding for SYMBOL and FONT?
I
suppose I could use mapscript, but I'd rather not.
Thanks!

This would indicate the answer is yes.

Binding would be with style'symbol, instead of class symbol. Font also
can be bound. I will update the docs to reflect that. The list of
binding elements is:
For style:
SIZE, WIDTH, ANGLE, COLOR, OUTLINECOLOR, SYMBOL, OUTLINEWIDTH, OPACITY
for labels: SIZE, ANGLE, COLOR, OUTLINECOLOR, FONT, PRIORITY

Dan,
Thanks for the reminder: "Google First"
It looks like both SYMBOL and FONT use binding.

Here's an example that draws a 1km diameter two different ways:
http://maps.dnr.state.mn.us/mapserver_demos/circles.map
It shows two ways to do this. One using a circle layer and the other
using a circle symbol but with different size units (e.g. non-pixel).
Apparently a circle layer takes features consisting of two points where
the points are on the circle and directly opposite one another. Their
mid-point defines the center point. Why I did it this way is a bit of a
mystery but it is what it is...
The buffer method is also perfectly valid.

After mulling this over I think I'm wrong. Conceptually it's correct but
the points represent the center and a point on the circle I think. I'll
post a stand-alone example later tonite...

In another approach, I believe MapServer wants you to define a bounding
box for the circle by creating a line shape with the first point at the
UL
coordinate of that box and the second coordinate at the LR coordinate of
the box. So you'd offset your center point .5 KM to create those points.
You can add the resulting shape to the appropriate layer to draw it.
I'll check to make sure, but I think that will work.

Hello List,
I want to be able to draw a circle dynamically using PHP MapScript. The
circle is defined by the coordinates of the centre and the radius in
kilometers. I realize that the circle is a polygon and I should probably
calculate all points. What is the best way to do it?
I would really appreciate any help!
Thank you,
