Re: [udig-devel] Single Band Raster Styling
|
Morning Emily,
I made it only in testing today, sorry, I am still abroad.
First off, this style editor rocks! Very nice work, thanks!
General: maybe the colortable combo should be alphabetically sorted, I
had hard time to find the table. And since most of the colobrewer
names are cryptic, it would be good to have a way to search better.
Anyways:
1) coloramp: works perfect
2) Intervals: works perfect
3) Unique values. I tried to do what a dummy would do and used a DTM
to create a colortable. It tried to calculate the unique value, stated
that only 256 could be allowed, threw:
java.lang.IllegalArgumentException: Comparison method violates its
general contract!

and after that it went in out of memory.

Hmmm, not sure about that. I tried 2 things:
1) add nodata to a ramp, and it works as expected
2) flag a whole interval as nodata and in the legend it is duplicated
(see attached image). While I thing I understand the reason it is
strange for the user (also an additional dash is added to the first)
3) if I add in the "Compute breaks.." a novalue, then nothing seems to
happen. I would imagine that a transparent rule for the novalue would
be added to the list. That would help to always know what I set as
novalue.
I add a couple of thoughts learned from using style:
- it would be nice to have an "export with one click" as in the vector
styles. What it does, is, that iif the layer is a file, it creates the
right named sld in the same folder. The export button is too slow for
such a "fast" thing
- it would be great to have something that "format" the number. Dtm
values will always be broken in double values with 8 numbers behind
decimal, so they will appear in the legend
Anyways, just thoughts, your work is great, I could play around with
it the whole day!
