Arcgrid reader only working with sample data
--------------------------------------------

                 Key: GEOT-1249
                 URL: http://jira.codehaus.org/browse/GEOT-1249
             Project: GeoTools
          Issue Type: Bug
          Components: gc arcgrid
    Affects Versions: 2.4.M1, 2.4.M0, 2.3.1
         Environment: Windows XP
            Reporter: despres damien
            Assignee: Simone Giannecchini
            Priority: Critical


ArcgridReader line 521 :
final Category values = new Category("values", demColors, new NumberRange(1, 
255), new NumberRange(0, 8849));

this values are correct for the example dataset but completely arbitrary for 
other datasets. I don't know how to correct it but i think it's not correct to 
apply such a style in the reader. 
I have a dataset with values from 0.0 to 9.0. if i use arcgrid reader, my 
values becomes 0.0 or 1.0 (because scaled from 0 to 8849.....)

It's like applying an arbitrary SLD directly in the reader.
