Hi Fernand,
OK i now how to use the provider but : I have a Dialog with a
ImageControlModel in it. How can i "show "(after loading with the
Provider) the graphic in the Dialog or in the "mageControlModel ???
You shouldn't need to care for this. As soon as the dialog is executed,
it will automatically create an ImageControl, which internally refers to
the ImageControlModel, and displays the graphic as indicated by the model.
OK no I get this to work with a Xgraphic object as the property from the
ImageControlModel but only when the Xgraphic object is obtained from a
"proper URL"
so i use 2 functions one for proper URL's and one I have to use the
"stream" when the Image is embeddend in a Writerdoc
function getGraphFromUrl(sFileUrl as String) as Object
oProvider = createUnoService("com.sun.star.graphic.GraphicProvider")
Dim oPropsIN(0)as new com.sun.star.beans.PropertyValue
oPropsIN(0).Name = "URL"
oPropsIN(0).Value = sFileUrl
getGraphFromUrl = oProvider.queryGraphic(oPropsIN())
end function
'-------------------------------------------------------------------
function getGraphFromStream(oInputStream as Object) as Object
oProvider = createUnoService("com.sun.star.graphic.GraphicProvider")
Dim oPropsIN(0)as new com.sun.star.beans.PropertyValue
oPropsIN(0).Name = "InputStream"
oPropsIN(0).Value = oInputStream
getGraphFromStream = oProvider.queryGraphic(oPropsIN())
end function
'-------------------------------------------------------------------
The Xgrahpic object "getGraphFromUrl " optained from the first Function
works as a property for the ImageControlModel
The Xgrahpic object "getGraphFromStream" optained from the Second
Function gives no "Image" in the ImageControlModel
In both cases i found (with Xray) the object in the ImageControlModel
but see no reason why the first shows up and the second do not shows up
?????
Thanks for any hint
If this doesn't work, it's a bug I'd say.
Ciao
Frank
