Hi all,
in connection with discussions in bug 108065, I looked at the export of
transparency in charts.
https://bugs.documentfoundation.org/show_bug.cgi?id=108065
[FILESAVE DOCX] Gradient property of the data series not preserved when
saved as DOCX
The problem has several reasons
a) void DrawingML::WriteGradientFill(awt::Gradient rGradient,
const uno::Reference<beans::XPropertySet>& rXPropSet)
expects a property "FillTransparenceGradient" but in charts only
"FillTransparenceGradientName" is available.
b) void ChartExport::exportFill( const Reference< XPropertySet >& xPropSet )
does not consider transparency gradient in case of solid fill.
c) import of a chart considers transparency only on data point filling.
What I have done so far is in https://gerrit.libreoffice.org/#/c/81165/1
My questions:
To get a gradient form "FillTransparenceGradientName", I have found
"com.sun.star.drawing.TransparencyGradientTable". To use it, I need a
model. That is available in class ChartExport, but not in the base class
DrawingML. Is there a way to get the gradient itself from its name in
DrawingML::WriteGradientFill()?
My idea for the export works for charts in Calc and Writer. But any
(e.g. a default shape without any gradient or transparency) export from
odp to pptx crashes. So I'm doing something fundamental wrong. But what?
Kind regards
Regina
