Hi,
I am working with apache
batik1.1.1.
In my program, There are
Steps:
1. parse the
svg file to the SvgSaxDocument,
2. build
SvgSaxDocument to the tree of GraphicsNode
3. transcoder the
tree of GraphicsNode to JPEGImage and send to user.
4. find out the
GraphicsNode selected by user on the tree generated in Step2.
5. modify these selected
GraphicsNode and redo the Step 3.
my questions is:
1. How to modify a
GraphicsNode to show ideally that it had been selected?
2. If I can easyly
change the fill color of a GraphicsNode?
3. Now, I had
maken a Filter Object by copying and modifying the code of some
FilterBridges.
That
filter can modify the fill color like SpecularLight Filter.
Then I call the setFilter() mothed, if there are not a filter ever, all is
right.
But
if there are a filter ever, all get bad. Example, if there are a feOffset
Filter to shift image ever,
after
I set my filter, the image can not be shift.
I am sorry, the upper questions must be
very mess.
I eager the whole perfect blue print
and any help from you.
Thanks,
ZD Ma.
