Partial Refresh
Hello all,
I still experience some refresh "bugs" in my application.
I have a (quite big) SVG, that I am trying to update in my application.
The modification consists in setting all colored stuff in the SVG to black fill and stroke.
So (part of) what we are doing for now is :
for (int j = 0; j < eltPattern.getChildNodes().getLength(); j++) {
Node temp = eltPattern.getChildNodes().item(j);
if(temp instanceof Element){
String strokeAttribute = ((Element)temp).getAttribute(SVGConstants.SVG_STROKE_ATTRIBUTE);
if(strokeAttribute.equals(refColor)){
((Element)temp).setAttribute(SVGConstants.SVG_STROKE_ATTRIBUTE, colorsPattern.get(i));
}
String fillAttribute = ((Element)temp).getAttribute(SVGConstants.SVG_FILL_ATTRIBUTE);
if(fillAttribute.equals(refColor)){
((Element)temp).setAttribute(SVGConstants.SVG_FILL_ATTRIBUTE, colorsPattern.get(i));
}
}
}
We added a refresh at the end :
svgPanel.getSvgCanvas().setRenderingTransform(svgPanel.getSvgCanvas().getRenderingTransform());
The modification is not correctly displayed in our canvas, but when I look at the exported SVG, via Squiggle, the result is OK.
Do someone know where my problem can come from
(I am using batik 1.8pre and I just added xmlgraphic 1.4, just in case...)
I Joined pictures of what is see too....
This is going to run my brain out :'(

Just so you know why this works. It works because changes to
the viewbox cause the entire graphics tree to be rebuilt (due to
the fact that any element using percentages might change).
You could get the same effect by removing the root SVG element
from the Document and adding it back, this is essentially what we do
under the hood. I suggest this because we don't always rebuild the
graphics tree and at some point in the future we might handle changes
to the viewbox in a more elegant way (of course we might handle changes
to patterns more elegantly by then as well...).

Just to tell that I managed to solve my problem.
Setting an initial viewbox to the SVG seemed to be our solution.
Thanks all for your help !

Hi Thomas, and thanks for your confirmation.
I found a bug in the list, that should explain that : https://issues.apache.org/bugzilla/show_bug.cgi?id=23443
I know that it is possible to see the correct result by setting attributes to node using the pattern but I still have some display problem.
I'll now be looking at the viewbox of our SVG... modifying this attribute in a test cases allowed me to display what I wanted...
Maybe I'll manage to do what I need one day ^^

This is the problem. Batik doesn't do a good job of tracking
complex dependencies like patterns. The only solution is to twiddle
all of the pattern references (set them to nothing then back to the
pattern).

This is the problem. Batik doesn't do a good job of tracking
complex dependencies like patterns. The only solution is to twiddle
all of the pattern references (set them to nothing then back to the
pattern).

This is the problem. Batik doesn't do a good job of tracking
complex dependencies like patterns. The only solution is to twiddle
all of the pattern references (set them to nothing then back to the
pattern).

Hi All,
As I can't give you the whole application, I created a sample of what I want to do.
I simply create a pattern and use it in the fill attribute of a <rect>...
The application consists in changing the pattern color when pressing space.
The SVG is also displayed in the console for information...
Do someone on the mailing list have this application working correctly ?
Nota : I have a color modification when zooming with the CTRL key and the mouse after having pressed space.

RE: Partial Refresh
Posted by Julien Beghin <mi...@hotmail.com>.
Hi Dao, and thanks for reading about my problems.
I tried to change this by setting setAttribute("xlink:actuate","none") and setAttribute("xlink:actuate","onRequest") but nothing more happens...
Couldn't this come from the fact that the pattern is identifed by its url for other elements of the SVG ?
I mean maybe the pattern is changed when I modify its attributes, but what about the elements using it ? Are they supposed to be refreshed by Batik ?
I thought we were respecting all Batik prescription when setting the canvas as Dynamic and using the runnable queue... but I must have missed a thing ...

perhaps it is because you specified xlink:actuate="onLoad" in the pattern attributes...

All our graphic operations are done in updatemanager :

Basically we are getting org.w3c.dom.Element and we use setAttribute to modify SVG contents...
It seems OK for most of our application.
Also, our SVG contains patterns like this :

</pattern>
</defs>
When this pattern is updated the result is not displayed ( if I do "getSvgCanvas().setSVGDocument(svgDoc);" result is OK, but that is not a good way to work... )
Node referencing the pattern with fill="url(#Autres_fluides_04db74e9...)" are not OK in the canvas...
Is there a specific way to implement the modification ?

This means that either your canvas is not set to 'dynamic' or
that you are not making your modifications in the UpdateManager's
runnable queue. I'm betting on the latter.

If you need to do this then you are modifying the document
incorrectly. Batik will update the canvas automatically if you
follow the rules.

Hi Thomas,

I am using a SVGCanavas Class, extending "JSVGCanvas" that contains the following -> setDocumentState(JSVGCanvas.ALWAYS_DYNAMIC);

This means that either your canvas is not set to 'dynamic' or
that you are not making your modifications in the UpdateManager's
runnable queue. I'm betting on the latter.

If you need to do this then you are modifying the document
incorrectly. Batik will update the canvas automatically if you
follow the rules.
