Enabling renderers to paint polygon fills and SVGs as vectors + paint marks
with arbitrary sizes
------------------------------------------------------------------------------------------------
Key: GEOT-2906
URL: http://jira.codehaus.org/browse/GEOT-2906
Project: GeoTools
Issue Type: New Feature
Components: core render
Affects Versions: 2.6.0
Reporter: Milton Jonathan
Assignee: Andrea Aime
Attachments: batik-export.vector+hatch.pdf,
geotools-tecgraf.2.6.x.vector_rendering+marks_with_arbitrary_sizes.patch
A patch is provided that covers some limitations found in the current renderers
(Shapefile and Streaming) as of 2.6.0. It follows discussions from thread
http://www.mail-archive.com/[email protected]/msg18546.html
The limitations and corrections are the following:
1. Currently, some elements are always rendered as raster images: polygon fills
are drawn as an AWT raster-based TexturePaint, and SVG ExternalGraphics are
converted to images in SLDStyleFactory. In this way, rendering GeoTools maps on
Graphics other than the screen (e.g., Batik's SVGGraphics and Graphics for
printing) gives outputs of limited quality. In order to solve this, a rendering
hint can now be provided to enable "vector rendering", so that polygon fills
are painted directly to the target Graphics and SVGs are not converted to
images. This is evidently slower, so if the hint is not provided, everything
still works as usual.
2. Marks are currently always assumed to be square (usually 1x1). This patch
also adds the capability of rendering marks with shapes of arbitrary sizes. As
such, shapes with rectangular dimensions of any size are now supported. A
separate patch will be provided that makes use of this capability to add new
shapes (such as hatches with arbitrary angles)
I am also attaching a PDF file that gives an idea of what we can do now with
these features (and the quality of the output). It contains hatches with
different angle values (green one is 45 degrees, black ones are 110) and SVG
files rendered as vectors.
