Hello,
I'm using OGR and MapServer to retreive and draw data from Oracle
Spatial. I'm using the styleitem auto tag in my mapfile, so that OGR
figures out the style automaticly.
Jelmer,
The existing Oracle OCI driver does not return style information for
features from Oracle, so generally speaking styleitem auto in MapServer
will not do anything useful against Oracle.
My test data is a number of polylines. I can change the color of the
line by setting PEN(c:#00ff00), but changing the line width doesn't seem
to work. When I try PEN(c:#00FF00,w:10px), nothing happens. I tried this
with px, pt, cm, big numbers, low numbers, nothing works.
Am I doing something wrong, here?
I'm not sure how you are trying to associate styles with features, so it
is hard to comment.
Also, I couldn't find anything in the documentation about multiple
styles per object. In MapInfo it's possible to have a 2px red line with
a black border, or a red dashed line with a blue background, for
example. Is that also possible in the OGR style?
Style tools can be concatenated with a semicolon seperator.
My suggestion would be that you do mapserver styling using mapserver
class/style primatives rather than trying to use OGR styling and styleitem
auto. Styleitem auto is most useful with formats like dgn, and mapinfo that
have extensive styling information intrinsic in the source data.
Best regards,
