the bounding shape of the image, used for select indicators

draw

public void draw(Traversal t)

Draws the image, called by the traverse method of FGlyph.

Overrides:

draw in class FGlyph

Parameters:

t - keeps the state of the traversal

loadImage

protected void loadImage(java.lang.String urlString)

Loads the image and sets the bounding box - shape_.
