I've been reading the StreamingRenderer trying to understand how the
layer's drawing process works.
When the StreamingRenderer draws the layer[1] it uses the
Graphics2D.drawImage method. Wouldn't be better to use the
Graphics2D.drawRenderedImage to apply the transformation (and get better

I think what diego needs is something different from what the
StreamingRenderer is supposed to do. This is why I am asking details
about what he needs to do.
If he has some specific needs I can drop some ideas that would help
him to get very high perfomances even with
Ciao Diego,
yeah, it's me again :-).
I am wondering about your goals
Could you describe exaclty what you are trying to do in terms of
sources of data and suported features? I could try and give some
directions as well as sharing some code that I have that would be
really handy for you. It
Hi all:
I'll try to describe my project:
- I'm developing a Swing application that will show a really BIG map
(150k x 100k px).
- I need to navigate through the image and the navigation speed is
critical.
- Even though the user must be allowed to zoom in an out
Hi,
I am trying to figure out how to get the minimum and maximum feature id
from a layer(feature collection/source) without loading all
features?
Is there any way to get this information?

Not that I can think of; the feature id concept is supposed to be a
I am trying to write geotiff with four corners and center known as well as
the projection. I would also like to add GCPs for the five points known

geotiffs written by GDAL just fine, but cannot seem to find any
documentation

Well,
If I get things right, you have a raster background, which you want to
visit at fixedresolutionlevels. You also want to overlay features on
top of this.
Well, I would suggest a simple thing. Use the streaming renderer to
render the features and then overlay this on top of the background

Not really. The module is abandoned, no one is taking care of it.
On 2.3.x it may be still working, on 2.4.x and trunk it
does not even compile and it's out of

Read the test cases; they are like documentation but actually running
code ;-)
Seriously the user guide is a collection of working examples as they are
placed onto this user-list; when well meaning individuals like yourself
post example code after figuring it out.

I wrote the EXACT same boundary information via geotools geotiffwriter and
via gdal_translate. Then did a gdalinfo on both versions of the file. The
information output by the gdal version of the file is accurate. The
information output by the geotools version of the file is wrong.
I did verify

FANTASTIC.. Just one more problem.. I don't know how to write the metadata

ge.setCoordinateReferenceSystem(crs);

Yes, I've been wandering this myself, I can't get the cursor to work properly
either.
