I am puzzled. When i draw a line by clicking, using ActiveImageEnView().MouseInteractLayers :=
[mlEditLayerPoints, mlClickCreateLineLayers];

i only get the end point. Nothing is drawn. not sure if i have to setup a brush.
See attached.

Hi

It's possible the line/border is not set (width = 0 or Color = clNone).

Try settings some layer defaults:

https://www.imageen.com/help/TImageEnView.LayerDefaults.html

e.g.
ImageEnView1.LayerDefaults.Values[ IELP_BorderColor ] := '$008000FF';
ImageEnView1.LayerDefaults.Values[ IELP_BorderWidth ] := '3';

same behavior. that's not it..it has to be something i am doing. let me work on it..the weird thing is that adding point to create a polyline work fine.

still cannot find the problem. if i have shapes at the start or end, they show but the line does not. Is there a way to find out the line color ? I assume i have a statement somewhere that makes the line invisible.

i even added
ImageEnView1.LayerDefaults.Values[ IELP_LineColor ] := 'clRed';
ImageEnView1.LayerDefaults.Values[ IELP_LineWidth ] := '6';
