Programmatically alter the default colour of .svg image? [message #543854]

Hey everyone,

Right now I use quite a few custom figures, which are read from .svg files by the ScalableImageFigure class.

What i'm trying to do now is programmatically manipulate the colour that shows up. That is, override the default .svg colour with one of my own.

For some reason, using the setBackgroundColor() method does not result in a change,
(though other methods of the same scope like setMaintainAspectRatio(), setVisible() all work).

I'm not quite certain why, and if any tips would help that would be great!!

Thanks!
PL

I've made some small progress!

modifying the paintFigure(Graphics graphics) method allows me to overwrite the foreground colour by using setRenderInfo for the image

basically before the listener call in paintfigure, i do this

rndInfo.setValues(rndInfo.getWidth(), rndInfo.getHeight(), rndInfo.shouldMaintainAspectRatio(), rndInfo.shouldAntiAlias(), new RGB(255, 255, 0), new RGB(255, 255, 0));
                setRenderedImage(getRenderedImage().getNewRenderedImage(rndInfo));

This changes the outline colour/fill colour!
But SADLY, background colour remains elusive, even though I am in fact offering a background colour RGB.. would anyone have any thoughts as to how to change the background colour as well?

Does SVG actually have a background colour, or is it transparent? If you
change the background colour and export to BMP, does the background
colour persist?
