Re: [Geotools-gt2-users] Horizontal alignment for texts along line

2019-01-11 Thread Ron Lindhoudt via GeoTools-GT2-Users 
 Thanks for your answers. I can use pointplacement with the starting point and 
a rotation and an anchorpoint of 0,0. Because of the anchorpoint of 0,0 the 
text should align horizontally and vertically at the origin of the point.But 
vertically this is not the case. It is quite a lot above.Probably this is 
because of the reservation for underlining?But I do not have underlining set, 
so the bottom of the text should align vertically with the origin.Is this a bug?
I can correct it more or less with an anchorpoint of 0, 0.25

Re: [Geotools-gt2-users] Horizontal alignment for texts along line

2019-01-10 Thread Andrea Aime 
No such a thing indeed. If you can be happy with a tangent (instead of
curved along the line) label then
you can probably get something going using the  tag and a point
placement with the
right rotation, using startPoint/endPoint and startAngle/endAngle functions.

If it's start/end and along the line... a new vendor option and the
corresponding code are needed I believe

Cheers
Andrea

I have a question:Is there a way to tell Geotools to align a text label with 
the start of the line instead of the center of the line?I cannot find it in the 
documentation of linePlacement.
The documentation is also very brief:
   
   -LinePlacement linePlacement(Expression offset,
Expression initialGap,
Expression gap,
boolean repeated,
boolean aligned,
boolean generalizedLine)  
  - Specified by:
 - linePlacement in interface StyleFactory
  - Parameters:
 - offset - 
 - initialGap - 
 - gap - 
 - repeated - 
 - aligned - 
 - generalizedLine -
