I have an image that renders well in ie (w/ adobe plug-in), and looks completely different with batik. Does anyone know what the problem is?
Hi Edward,
The problem is the use of patternContentUnits="objectBoundingBox". take the example from the specification:
<pattern x="10" y="10" width="20" height="20"> <rect x="5" y="5" width="10" height="10"/> </pattern>
In this case the rectangle's top left corner is 5 pixels over/down from the pattern tile's origin (this uses the default userSpaceOnUse for patternContentUnits).
But when you say "objectBoundingBox" this says that the coordinate
system (within the pattern tile) is established using the objects
bounding box. So in this case 0,0 is mapped to the coordinates of
the object's upper left corner, _not_ to the tile's upper left corner.
In your case the objects upper left corner is not 0,0 so the pattern contents appear 'shifted' in Batik. Adobe appears to ignore this
translation and only apply the scaling portion of the transform.
The 'fix' for this is to use viewBox="0 0 1 1" preserveAspectRatio="none" which says map the coordinate space
0,0 -> 1,1 to what ever space x,y w,h define. Which appears to be
what you want.
