loading styles.xml into document

I realize the styles are all stored as a zip context of the document *.odp upon extracting it, the styles.xml and a couple of other necessary .xmls are there to facilitate the ooo engine to load such data upon opening of odp document.

I was wonder if it is possible to load a styles.xml manually into a open document thus forcing that document to adopt the styles adopted on the styles.xml instead of those of its own styles.xml at runtime?

I understand from the previous threads that if i add my custom styles.xml to replace that in the .odp, it would delete the rest of the files. Also it would not be dynamic if i create a new zip with my customize styles.xml afterwhich renaming to .odp, it will only be updated on the next load of this document. Is there a way i could call thur the API or via .uno:cmd to load a custom styles.xml forcing the document to adopt my style at runtime?

Thanks

did you check if XStyleLoader ( http://api.openoffice.org/docs/common/ref/com/sun/star/style/XStyleLoader.html ) is supported by .odp docs ?

hmmm it's able to load from xml? cos from the API don't looks like it really can do so.
I will check and post back.

I got a nullpointer exception... No idea why..
I tried obtaining the graphic style from odp document and event styles.xml which is extracted from a odp but still get the nullpointer.

I also tried parsing the background properties of the Default style but get nullpointer too. Wonder if its wrong concept?

com.sun.star.style.XStyleFamiliesSupplier xSFS = (com.sun.star.style.XStyleFamiliesSupplier) UnoRuntime.queryInterface(
com.sun.star.style.XStyleFamiliesSupplier.class, XModel);

com.sun.star.container.XNameAccess xFamilies = xSFS.getStyleFamilies();

// the element should now contain at least two Styles. The first is
// "graphics" and the other one is the name of the Master page
// (Default or masterpagename)
String[] Families = xFamilies.getElementNames();

//try to change all the style for graphics
Object aFamilyObj = xFamilies.getByName(Families[0]);

//obtain the style through queryinterface
com.sun.star.style.XStyle xStyle = (com.sun.star.style.XStyle) UnoRuntime.queryInterface(com.sun.star.style.XStyle.class, aFamilyObj);

//get style loader
XStyleLoader xStyleLoader = (XStyleLoader)UnoRuntime.queryInterface(XStyleLoader.class,xStyle);

xStyleLoader.loadStylesFromURL("file:///E:/myslide.odp", new PropertyValue[0]);

you are right, I checked with xray: My proposal does not work. Writer supports the loading of styles, but impress doesnt...

Hi,

things turned out to be much more complicated that I thought initially ... the following is not yet the solution, but a point to start. The code expects that you have a user defined style "ms777" in your source document (antialias.odp), which you want to copy to the actual .odp:
