Re: [Geotools-gt2-users] User Manual Errors [was: Transform Screen to Lat/Long & Posible error in UserManual]

[Diego Fdez. <di...@go...>]

Hi all:
=20
 I was trying to fix an example[1] but I'm lost in the dark. The example
says:

 Geometry screenGeometry =3D geometry.transform( screenCRS, transform );

 But I don't know how to get a Geometry, so I go to the Geometry section
in the user manual[2] but:

 GeometryBuilder builder =3D new
GeometryBuilder(DefaultGeographicCRS.WGS84);

 it doesn't work because org.geotools.geometry.GeometryBuilder package
(I'm using 2.3) doesn't exist.
 And even if I get this working: how can I create the screenCRS?

 I've look at the source code of
RendererUtilities.worldToScreenTransform but it's not applicable to make
a simple example.

 Please. I need help in A LOT of simple things. I will send then back to
the list as _working_ code snippets so the user manual gets updated and
other people can learn from my faults.

	Thanks!

 P.S: IMHO the user manual has many "underexplained" examples. It's very
hard to a newcomer to learn how to use GeoTools in deep. I know many of
you life from supporting GeoTools by contract, but I also think that
having a good documentation would make that a lot of people use the
library and this will end in many more company programmers using
GeoTools, programmers from companies that will pay you for support. :)
