Description henry.ernst@snafu.de 2020-04-04 13:08:38 EDT

Dear Teechart-Team,

i use Delphi 10.2.3, Teechart Pro 2019.27.190530 VCL and Windows 10.0.18363.

The users of my software can copy a Chart to Clipboard.
To do this with "Chart1.CopyToClipboardMetafile(true);".

But on Devices with Textscaling more than 100% (i.e. Surfacebook 2 with 200%) there is an issue.
After pasting the graphic in Word or Powerpoint there is an frame for the hole graphic. But the content of the chart take only a part (i.e. quarter) from the frame.

You ca reproduce the problem with the attached sample.
Is ther any workaround or bugfix for this problem?

Thanks and regards Henry

Hello Henry,

We can offer you alternative code to achieve the CopyToClipboard.

Excerpt taken from this forum thread:
https://www.steema.com/support/viewtopic.php?f=3&t=15936#p70743


Code:
procedure TForm1.Button1Click(Sender: TObject);
var tmpRect: TRect;
    tmpWidth, tmpHeight: Integer;
begin
  tmpRect:=Chart1.GetRectangle;
  tmpWidth:=tmpRect.Right-tmpRect.Left;
  tmpHeight:=tmpRect.Bottom-tmpRect.Top;
  tmpRect.Right:=tmpRect.Right+tmpWidth;
  tmpRect.Bottom:=tmpRect.Bottom+tmpHeight;
  Chart1.CopyToClipboardBitmap(tmpRect);
end;

Regards,
Marc

You may want to "Enable High-DPI" in your project options, concretely under "Application".
In Rio and Sydney, more options where added and the preferred way to go is by using "Per Monitor v2" "DPI Awareness" under "Application/Manifest".

Setting this option, the given project seems to work fine without any extra code.
