Well, sort of.
As you may have guessed, I'm a relative Batik novice.
What puzzles me is that the transform returned by
getViewingTransform() in the main thread is significantly different
than that returned by the same method in the update thread.
Is the viewing transform returned in the main thread actually valid?
If so, how does it relate to the transform in the update thread? How
does the transform returned by getViewingTransform() relate to the
transform returned by the AbstractGraphicsNode getTransform() method,
if at all? How about the transform returned by getGlobalTransform()?
And why the heck are there so darned many transforms? :-)
Is this documented somewhere? Is there an O'Reilly book? :-)
Perhaps I'm going about this all the wrong way.
In case this makes any difference, what I'm attempting to do is to
overlay an image of a rat or mouse brain slice with some pre-existing
SVG graphics from a standard brain atlas to allow a user to establish
correspondences between the acquired image with that standardized
atlas and perform the appropriate warping of the image. The warping I
know how to do -- it's figuring out how to initially scale the image
that's bugging me.
