I create a textlayer using:

function LayersAdd(Text: String; FontSize : Integer; FontColor : TColor; FontName : string; FontStyle : TFontStyles = []; PosX: Integer = -1; PosY: Integer = -1): integer; overload;

Later on this layer may be moved or resized manually. Thus I identify the layer with a unique layer name (ULN):

for i := 0 to ImageEnView1.LayersCount - 1 do
    ln := CompareStr(ImageEnView1.Layers[i].Name, ULN);
  if ln = 0 then
    begin
      idx := ImageEnView1.LayersNameToIndex(ULN, False);
      ImageEnView1.LayersCurrent := idx;
    end;


and set the mouse interact layer options:

ImageEnView1.LayerOptions := ImageEnView1.LayerOptions + [ loAllowMultiSelect, loAutoSelectMask ];
ImageEnView1.MouseInteractLayers := [ mlMoveLayers, mlResizeLayers ];

As result, the layer is selected correctly with the eight yellow circles but is neither moveable nor sizeable. The only operation which is allowed is the creation of new layers inside the layer area.

May you give me a hint what I'm missing?

Hi Nigel,

the error should've been caused by wrong MouseInteractLayers parameters. I solved it by resetting the parameters using ImageEnView1.MouseInteractLayers := [] as shown in the Layers demo.

Thank you,
Al

Hi Nigel,

behaviour doesn't change using ImageEnView1.LayersDeselectAll();

I just tried "Rotate Layers Demo" which works fine but it is limited in calling the parameters, same thing my code does. I'll try to simplify my code and continue to dig to find the cause.

PS: "Rotate Layers Demo" contains an error. Both procedures, Move and Rotate, use the same parameters [ mlMoveLayers, mlResizeLayers ]. You should modify the ones in the Rotate procedures in [ mlMoveLayers, mlRotateLayers ].

Hi Al

I cannot reproduce that. Ensure you call ImageEnView1.LayersDeselectAll(); before setting LayersCurrent to clear the existing selection.

Are you able to reproduce in our Layer editing demos?
