changing resolution problem -- rectangles not getting affected

[Amit Srivastava]

  
I am using TiffTranscoder to convert svg to tiff .
The tiff files created are having resolution 0f 94 X 94 by default.
If I increase the resolution by
t.addTranscodingHint(TIFFTranscoder.KEY_PIXEL_UNIT_TO_MILLIMETER, new Float(0.15));

the text lines are increasing in length in the resulting tiff files but the 
<rectangle> elements are not getting affected (even if text and rectangle are in same 
<g>).
So, text is crossing over the rectangles.

Any idea why as there are many rectangles and editing will take lot of efforts.

thanks.
