Thanks Tom,
after switching to a 3D display with a 2D renderer your solution with
the transformation matrix does it.

Thanks, I will look into the Javadoc issue. I've been trying to keep
the javadoc jar file in sync with the releases but I must have a
mistake in my "build" procedure.
Regarding the box size, here is the code snippet from the subs.py that
does this -- you'll have to cast it into Java, though...unless you're
using Jython!
def setBoxSize(self, percent=.70, clip=1, showBox=1, snap=0):
"""
Set the size of the VisAD 'box' for the <display> as a percentage
(fraction). The default is .70 (70%). If <clip> is true, the
display will be clipped at the border of the box; otherwise, data
displays may spill over. If <showBox> is true, the wire-frame will
be shown; otherwise, it will be turned off. If <snap> is true, the
box will be reoriented to an upright position.
"""
pc=self.getProjectionControl()
if (not snap) or (self.pcMatrix == None):
self.pcMatrix=pc.getMatrix()
if len(self.pcMatrix) > 10:
self.pcMatrix[0]=percent
self.pcMatrix[5]=percent
self.pcMatrix[10]=percent
else:
self.pcMatrix[0]=percent/.64
self.pcMatrix[3]=-percent/.64
pc.setMatrix(self.pcMatrix)
dr = self.getDisplayRenderer();
if __ok3d:
try:
if isinstance(dr, DisplayRendererJ3D):

Hi,
if a similar message from me is always on the list then it is a
mistake, but as I can't see it, I will ask this question a second time.
For my current project I have to compose pictures from different
plots to generate a video from them. The off screen rendering works
fine. The only problem is that the images from the off screen
displays have a large empty border around the plots. So the question
is, how can I reduce this border programmatically?

PS: I suggest to repackage the Javadoc jar file. I have noticed the
email from tom that there is a new build of VisAD. The size of the
docs jar file is far to high. It contains the documentation twice
under a folder called docs. One time as the documentation itself
ordered into different sub folders and the second time as a jar file
of these folders.
