Hi Michael, hi everyone,
Here is how to use the NumberFormatFunction.
1) First, you have to register it so the factory can find it
dynamically.
To do so, you have to create a META-INF/services folder in your jar
file and put in it a simple text file called
"org.opengis.filter.expression"
Hi Ben,
Many thanks for posting your code. I've just been studying it. If
it's not too much trouble could you post a little snippet sometime
showing how you would use this programmatically please ? No hurry.
cheers

Thanks Andrea !
I found what I did wrong. I used two Strings instead of a String and a
Double. Your example helped me to find this rather trivial mistake.
Here is the working code, for those who are interested.

OK for the text symbolizer, I have replaced the code as you said.
Regarding the evaluate method, I have evaluated the two parameters
against the object as you said (see below).
I have built the formatter from the string result.
But then, I don't know what to return. I have tried (T)
formatter.

Hi everyone,
As Andrea suggested, I'm trying to implement a formatting filter
function that could be used in SLD files (or programmatically) to
display text in a given format, like this :
myAtt
##.##
I have looked at existing functions and coded the function attached.
However, I still

Mumble... it's part of the label placement structure, it can
be a point placement, or a line placement. If
I found how to do it:
text.setLabelPlacement(sb.createPointPlacement(0.5, 0.0, 0.0));
It's still another deprecated method (setLabelPlacement), but there is
a way to avoid it :
StyleBuilder sb = new StyleBuilder();
org.geotools.styling.Font[] fontArray = {sb.createFont(new
Font("sansserif",
Thanks Andrea,
I did not try to set my AnchorX to 0.5.
How do you do it ? I couldn't find any documentation to access the
anchor point of a TextSymbolizer.
Regarding the new function, I will give it a try and let you know.

Okay cool; so have you tried the text symbolizer offset yet? Setting an
offset should allow you to draw above or below the line. There is also a
rendering hint that can be used to make the text follow the line; I am not
sure if that only changes orientation or if it also would calculate an
offset?
Hi Jody,In fact, I have to draw a grid. Each segment of the grid is displayed in a different color, representing the depth of the water at a given point.To make it more readable, I also have to be able to display the value of the depth of each grid segments. (see attached file)For vertical segments
The style visitor is there to go over all the elements in a style data
structure (so you do not have to use get methods so much).
I am still trying to sort out what you want to do? Are you trying to make
your text flow along your linestring? Or go in the same direction as your
line string or what .
Hi List !
I'm still working on styles and I have create a TextSymbolizer that
indicates the value of my linear shaped feature.
I don't use SLD file but rather create my styles programmatically.
I want to do two things with my text :
- first, I want it to be centered with respect to the associa
