Ciao Simone,
no problem, it's open source :-) it's me who has to apologize for
bothering you with "me to stupid to fix classpath issues" :-).
Maybe I should describe my path to the pyramidbuilder before describing
my usage. I am putting together a demo client with
gt-widgets-swing-pending-2.5-M2. Just display some points, styled
according to some attributes.. quite basic stuff. To make it look nice I
integrated a background image, but... area covered by the points was too
big to have one file.
As I had 5 images, different detail level, I decided (after reading the
user guide) that the ImagePyramidReader is my friend. Searching the list
and the docs I stumbled on PyramidBuilder. After I fixed my classpath
problems and the null pointer in the PyramidLayerBuilder I generated 5
pyramids (starting PyramidBuilder with: -s raster.tif -t "500,500" -f 2
-n 4 -w ), one for each detail level, and then manually merged the 5 to
a reasonable pyramid, mostly by simply copying the "0" directory of the
less detailed pyramids to the "2", "8",...
What I got was 5 directories, each with the tiles, a shapefile and and a
properties file.
Played around a bit, adjusted the scale levels in the main
pyramid.properties (to make use of all generated layers, with the
default only 0,2 and 4 was used, 8 and 16 were not touched), and e voila
it was up and running with three lines in a slightly modified version of
DemoAll.java from gt-widgets-swing-pending-2.5-M2.
URL pyramidURL=
AplsGisTestClient.class.getResource("pyramid/pyramid.properties");
ImagePyramidReader pyramidReader = new ImagePyramidReader(new
File(pyramidURL.toURI()));
context.addLayer(pyramidReader, RANDOM_STYLE_FACTORY.createRasterStyle());
Performance of the client is good, I'd expected the whole thing to be
much slower, but it's very responsive when zooming and panning.
Thanks,
Tom
