Great to hear you got it working.
You can just use the MapContext instead of creating a separate list of
FeatureSources if you want...
//Select the shapefile to work...
FeatureSource f =
mMapContext
I'm just calling polygonSymbolizer.setFill(styleBuilder.createFill(new
ColorRampFunction(colorList))). I have one featuretypestyle with one rule.

You don't need to worry about adding a LineString etc. Instead you

So, you are telling me that you get that error right away during a

This is rather strange, we might probably want to chat a bit on IRC

Ciao jan,
i have tested the file you sent me with geotools 2.6.x and it worked fine.
Can you give some details about the system you are playing with? Java
versions, sisop, etc..?
Also it might be worth to try 2.6.4, which has just been release.

Hi Jan,
the TIFF 6.0 specification states that "*The entries in an IFD must be
sorted in ascending order by Tag*": (See Section 2, page 15 at [1])
As suggested by Simone, I think that the ImageI/O is not happy to handle

Jean Marie,
if you don't have to parse the wkt for some internal reasons, you can use the
EPSG db provided by GT.
You can then do:
boolean forceLonFirst = true;
crsDest = CRS.decode("EPSG:4326", forceLonFirst);
When you parse a wkt, I think it takes what you exactly specify. You could

Hi Jan, Thanks again.
I´m trying to examine a Landsat7 multispectral image, with 7 bands in a single
TIF file, and some metadata in it´s header.
I just want to access to pixels of each band and manipulate them to make some
corrections, and leave the TIF with the same metadata.

Hello
surely an easy problem but I don't find the way to solve it

i do some tranformation from one coordinate sytem to another

Ciao Jan,
this does not look like a problem related to having or not some
dependencies in your path.
It looks like imageio is not able to correctly read this tiff.
-1- Can you try a gdalinfo on it and paste the result?
-2- Can you send over some sample data?
Simone.
