When querying a XGraphic from a URL, the size of the Graphic is always
the original size coming from the URL, the FilterData seems to been ignored.
The result from my function "getGraphFromUrl" returns always the orginal
graphic size and not the demanded 500x1000 pixels
When Storing to a URL the Graphic takes the size asked by the Filterdata
the result of my sub "storeGraphicToURL" gives a graphic 500x1000 pixels
Can someone confirm this behaviour or I am doing something wrong.
of course the work around is simple, query first, store to a temp
location and query again ....
Thanks for any hint

function getGraphFromUrl(sFileUrl as String) as Object
oProvider = createUnoService("com.sun.star.graphic.GraphicProvider")
'creating filter data
Dim aFilterData (1) as new com.sun.star.beans.PropertyValue
'properties valid for all filters
aFilterData(0).Name = "PixelWidth" '
aFilterData(0).Value = 500 'pixels
aFilterData(1).Name = "PixelHeight"
aFilterData(1).Value = 1000
Dim oPropsIN(1)as new com.sun.star.beans.PropertyValue
oPropsIN(0).Name = "URL"
oPropsIN(0).Value = sFileUrl
oPropsIN(1).Name = "FilterData"
oPropsIN(1).Value = aFilterData()
getGraphFromUrl = oProvider.queryGraphic(oPropsIN())
end function
sub storeGraphicToURL(xgraphic,exportURL)
gProvider = createUnoService("com.sun.star.graphic.GraphicProvider")
Dim bArgs(2) as new com.sun.star.beans.PropertyValue
'creating filter data
Dim aFilterData (1) as new com.sun.star.beans.PropertyValue
'properties valid for all filters
aFilterData(0).Name = "PixelWidth" '
aFilterData(0).Value = 500
aFilterData(1).Name = "PixelHeight"
aFilterData(1).Value = 1000
bArgs(0).Name = "URL"
bArgs(0).Value = exportURL
bArgs(1).Name = "MimeType"
bArgs(1).Value = "image/jpeg" 'geen "jpg" wel "jpeg"
bArgs(2).Name = "FilterData"
bArgs(2).Value = aFilterdata
gProvider.storeGraphic(xgraphic,bArgs())
end sub
