Hey,
I think theres a bug in getLegendGraphic - the image comes out padded
with whitespace.
If I request a LegendGraphic that's 150 pixels wide, I only get 100
pixels of image, padded by 25 pixels of whitespace either side of the
image. The same goes for the height - only about 2/3 of the image is
used. The problem escalates the larger the image is.
This poses a problem at least for me because when displaying
LegendGraphics on a screen I want to be able to control how much
whitespace is around the image, using html or css attributes on, say, a
table. Right now its taking up 50 valuable pixels of my display 
Could one of you please let me know if I should file this as a bug, or
is it supposed to be like that?
Thanks,
Miles

Gabriel wrote that code, perhaps he has some insight in to it.
Gabriel? Any thoughts?

hhmmm.. yeah, though I don't have the code at hand, I'm pretty sure we're
padding by a percentage of the image dimensions.
The spec says nothing about if thats a correct behavior, its completely up to
implementors. You'll find a similar issue if you expect the returned image
being exactly of the size specified by the width and height parameters: if
your sld has more than one rule, the returned image will be scaled up on the
Y axis to return a stack of representative graphics, one for each rule.
Back to the padding issue, I'm quite realizing that what we're currently doing
is wrong. It makes more sense to let the graphic fill the whole image and let
the client take care of layout, so yeah, please add it as a jira task, so it
gets not lost in the archives. I hope to have a run over a bunch of my
pending tasks starting next week.
Gabriel.
