we already have support for reading GeoReferencedRaster.parseGDALMetaData(URI
uri) (seems format agnostic too). but that is depending on GDAL installed,
while the implementaion in TiffUtils.calculateStats() seems be plain java
utilizing some apache commons imaging code but is limited to TIFF files.
note the following comment in GeoRefRaster
/**
* initialize the img and try to parse geo infos via (in this order)
* worldfile, gdal or geotiff
*/
protected void readRasterfile() throws ReferencedImageException {
tl;dr i am good with keeping the addtional metadata reading within TiffUtils
generally. still you my want to consider a caching approach there as well if
the info is accessed more than once and expected not to change over the course
of the runtime.

I will make those changes. Statistics are calculated in order to reuse on
raster analysis (sextante). It is also saved into a special .aux.xml sidecar
file.
At this moment there is no need to implement GeoReferencedRaster with Statistic
read as it is uìused only by Sextante.

hey Peppe,
nice try, but no dice. the reason i created an explicit TiffUtilsV2 was
to make sure it contains no reference to RasterImageIO or TiffTags
anymore. the idea is to wrap GeoReferencedRaster functionality to reuse.
GeoReferencedRaster includes all functionality for retrieving an
Envelope or dimensions needed.
If you are lacking functionality in GeoReferencedRaster we may add it
accordingly.
i cut some code parts below and commented them which should be replaced
by using GeoReferencedRaster routines. ..ede
