Jesse Ramos created GEOT-3979:
---------------------------------
Summary: Opacity ignored for Glyph.point/line methods
Key: GEOT-3979
URL: https://jira.codehaus.org/browse/GEOT-3979
Project: GeoTools
Issue Type: Bug
Components: main, render
Affects Versions: 2.7.1
Reporter: Jesse Ramos
Assignee: Jody Garnett
Priority: Minor
Attachments: Glyph.java, SLD.java
Hi,
I'm creating PointSymbolizer, LineSymbolizer, and PolygonSymbolizer's with the
opacity set for each as follows:
{code}
StyleFactory styleFactory = CommonFactoryFinder.getStyleFactory(null);
FilterFactory filterFactory =
CommonFactoryFinder.getFilterFactory(null);
Mark mark = styleFactory.createMark(filterFactory.literal(shapeWktName),
null,
styleFactory.createFill(filterFactory.literal(color),
filterFactory.literal(opacity)),
filterFactory.literal(size), // size
filterFactory.literal(0)); // rotation
Graphic graphic = styleFactory.createGraphic(null,
new Mark[] {mark},
null,
filterFactory.literal(opacity), // opacity
filterFactory.literal(size), // size
null); // rotation
return styleFactory.createPointSymbolizer(graphic, null);
{code}
{code}
StyleFactory styleFactory = CommonFactoryFinder.getStyleFactory(null);
FilterFactory filterFactory =
CommonFactoryFinder.getFilterFactory(null);
return
styleFactory.createLineSymbolizer(styleFactory.createStroke(filterFactory.literal(color),
filterFactory.literal(size), filterFactory.literal(opacity)), null);
{code}
{code}
StyleFactory styleFactory = CommonFactoryFinder.getStyleFactory(null);
FilterFactory filterFactory =
CommonFactoryFinder.getFilterFactory(null);
return
styleFactory.createPolygonSymbolizer(styleFactory.createStroke(filterFactory.literal(outerColor),
filterFactory.literal(outerSize)),
styleFactory.createFill(filterFactory.literal(innerColor),
filterFactory.literal(opacity)),
null);
{code}
When adding Styles to a MapContext that have Rules that use these symbolizers
the resulting image is what I expect. The opacity values are used correctly
when generating the images.
However, when creating a legend I am using
Glyph.point(Rule)/line(Rule)/Polygon(Rule) to generate the legend image icons.
For the Polygon image the legend image opacity matches the Rule that is passed
in. For point and line, however, the opacity does not change with respect to
the Rule.
I've attached a couple of files with minor code changes that fix the issue for
me in case they help. Not sure if they are 100% correct or not but at least
point out where I think the problems lie.
