Hi Koldo,

As a matter of fact , I added a 'AddDrawing' method to my report generator package:

void ReportGenerator::replaceDrawing(const StringType& label, const Upp::Drawing& inputDrw, Upp::Size destSize )
{
	Upp::String s;
	if (!inputDrw.IsNullInstance() )
	{
		if (destSize.cy != 0)
		{
			if ( inputDrw.GetSize().cx*100/inputDrw.GetSize().cy > destSize.cx*100/destSize.cy )
			{
				s << AsQTF(CreateDrawingObject(inputDrw, destSize.cx,0));
			}
			else
			{
				s << AsQTF(CreateDrawingObject(inputDrw, 0, destSize.cy));
			}
		}
		else
		{
			s << AsQTF(CreateDrawingObject(inputDrw));
		}
	}
	else
	{
		replaceImage(label, ReportGeneratorImg::EMPTY_IMG(), destSize);
	}
	replaceVar(label,s);
};

The code is inspired from another Upp package from Sergei I think.
I preferred to use the a DrawingObject object instead of passing by an intermediate Image like in you're example: this keeps the pdf files as light as possible.

This works very well with the PieChart ctrl (see the sample report I joined ) but with the Scatter ctrl, it doesn't work: I see the graph but the points are to small to appear and the fonts are almost unreadable Sad

I know something is done when CtrlLayoutxxx() methods are called but I don't understand the philosophy of the 'xxxZxxx()' methods which are used to counter the problem I have and since the PieChart and Scatter don't behave the same ... I'm stuck for the moment

BTW: the report joined is completely generated from SQL data including images and charts.
