[Biojava-l] how to do multi-lined feature display

[Patrick McConnell]

Using the imagemap infrastructure works really well.  Thanks!  It tooks
some time figuring out how to hook together all of the renderers, but I
attribute that to my lack of experience with BioJava.

I noticed that the ImapRenderer takes a URLFactory for mapping URLs to
hotspots.  URLs are somewhat too restrictive here because URL's do not
allow for relative links, internal links (via #), or javascript.  I think a
String is more suitable.  That being said, you can get around this simply
by constructing the URL when you print your image map out instead of during
image rendering.

I am having some problems spacing features out vertically with a
MultiLineRender.  My MultiLineRenderer draws directly to the
HeaderlessContext, and all of the feature blocks are bumping against each
other vertically.  How do I add some padding?

Thanks again!

-Patrick

Sorry about the delay replying - one host I use here has been silently
dropping a lot of my outgoing mail. This is reply is regarding
imagemaps...

There is some imagemap infrastructure in the same package as the
SequenceRenderers which might be some use; see the ImageMap interface,
its ClientSide and ServerSide implementations, the HotSpot class
(which encapsulates coordinates, a URL and an optional user Object)
and the ImageMapRenderer interface.

ImageMapRenderer is a decorator for FeatureRenderer which provides a
method for creating suitable coord Strings. The current impls are a
bit sucky because I haven't had time to factor out the common parts of
the image-drawing and HotSpot-creating code. Right now there are
imagemap renderers for RectangularBeads and Ziggys, but it's a bit of
a pain creating new renderers.
