Re: Displaying elements with gradients in on-the-fly build SVGDocument

Hit Thomas,

I use batik 1.7 official release. Because time is of essence for me now 
I found a workaround (not pretty I admit) - after creating document, I 
save it as a temporary file on disc, and load it to canvas. That 
resolves the problem.

I was a bit surprised but I didn't see any stacktrace and didn't get any 
error message while opening this document. However, before aplying the 
above mentioned workaround I observed one more interesting thing. When I 
ommited this gradient styles in <defs> node, batik showed an error 
message stating that styles used in nodes cannot be found. After adding 
the styles the error didn't occur, but still (as I mentioned before) 
nodes with gradients were not drawn.

Best regards,
Maciek

This works fine until I have some gradients defined in <defs> node. In this case no exception is thrown but the elements using gradients are not drawn at all.
