Description narcís calvet 2013-11-20 10:38:48 EST 
Exporting a chart with a transparent GridBand to an image or printing it via the chart editor ignores transparency:
uses Series, TeeTools, TeeStore, TeeBmpOptions;

procedure TForm1.FormCreate(Sender: TObject);
var GridBand1: TGridBandTool;
 Bitmap: TBitmap;
begin
 Chart1.AddSeries(TLineSeries.Create(Self)).FillSampleValues;

 GridBand1:=TGridBandTool.Create(Self);
 GridBand1.Axis:=Chart1.Axes.Bottom;
 GridBand1.Band1.Color:=clBlue;
 GridBand1.Band2.Color:=clRed;
 GridBand1.Band1.Transparency:=50;
 GridBand1.Band2.Transparency:=50;

 //Bitmap with transparency
 Bitmap:=Chart1.TeeCreateBitmap;
 Bitmap.SaveToFile('C:\temp\GridBandTest1.bmp');

 //Bitmap without transparency
 TeeSaveToBitmap(Chart1, 'C:\temp\GridBandTest2.bmp', Chart1.ChartBounds);
end; [created:2011-04-04T15:45:14.000+01:00 reported by:narcis@steema.com reported in version:2010.02.20202 (TeeChart VCL)]
