How can I write the information about the measurement info (the same appeareance) into the image, in the mouseup-event?

Posted - Feb 28 2023 : 16:06:39 That looks correct. The left 5.03 is not anti-aliased because LayersFastDrawing is enabled, and the right 5.03 is the sizing hint.
Are you looking for the text to be above the line?
Posted - Feb 28 2023 : 13:20:03 I see this, if I move the mouse:

Strictly speaking it is better to use OnLayerNotify to know the get the end of layer creation:
procedure TForm1.ImageEnView1LayerNotifyEx(Sender: TObject; layer: Integer;
event: TIELayerEvent);
begin
if event = ielCreated then
ImageEnView1.LayersMerge();
end;
But I cannot see any issues either way. Can you post some screenshots of what you are seeing?
But as an result I get a black rectangle at the left side (or top), with the meausrement-info in it and connected with a line. But the measurement is not right, it seems that the size of the rectangle.with (or hight, depends on the direction the mouse is moved) is substracted.
Do I something wrong here?

If you are wanting the same effect as the measure interactions (e.g. miMeasureLength), but have the layer persist after positioning, then use a layer creation interaction, such as mlClickCreateLineLayers (and in the OnNewLayer event enable RulerMode).
Then to "burn" it into the image you can use LayersMerge();
Posted - Feb 21 2023 : 17:35:27 Yes, thank you, but my question is, how to paint the rulerinfo persistent to the image (not as layer, that escapes, when the measurement ends).
