Assign a back image by code

Post by johnnix » Thu Jul 21, 2016 7:25 am

Hello,

I am facing a strange issue with back image and TeeCreateMetafile so first I would like to ask if my code for assigning a back image is correct:

Code: Select all

  aBit := TPngImage.Create;
  try
    aBit.LoadFromResourceName(HInstance, 'PngImage_2');
    MyChart.BackImage.Assign(aBit);
  finally
    aBit.Free;
  end;
Do I need to call anything else? FYI the chart displays correctly on the screen but when the TeeCreateMetafile is called it looks like the plot is drawn twice!
