How would I display vector objects in imageenMview?
right now, when I add a box to a layer, it does not show up in my layers?
Hope I am making sense.

| Hold on. I may have found a demo that may help me. Will update the thread if not. |

Nope, the demo was not with vectors. Any help coding. This is what I am using but it does not show vectors.
LayerView.CenterSelected;
// update ImageEnMView1 with the contents of ImageEnView1
LayerView.Clear;
for i := 0 to ImageEnVect.LayersCount - 1 do
begin
idx := LayerView.AppendImage;
LayerView.SetIEBitmap(idx, ImageEnVect.layers[i].Bitmap);
if i = 0 then
LayerView.ImageTopText[0].Caption := 'Background'
else
LayerView.ImageTopText[i].Caption :=
string(ImageEnVect.layers[ImageEnVect.LayersCurrent].Name);
end;
LayerView.SelectedImage := ImageEnVect.LayersCurrent;
LayerView.Update; |

| Thank you. I will work on that at the same time. Appreciate it. |

1. Do your layers contain a bitmap or are they transparent?
2. Do you want the objects created so they can be moved off a layer (can be moved anywhere) or do you want the objects to be contained within or anchored to the layer?
3. Which background image do you want to appear in the thumbnail... the background (layer 0) or the selected layer (1..xx)?

The layers by default are transparent but the user can load a bitmap. Either way.
Yes, the boxes needs to be moveable and resizable. But it is best for them to be anchored to the layer. Will have to check. I need to be able to move the background image while the boxes do not move. They both should be on the same layer.
The thumbnail should show the current background layer. I have the ability to load images into each layers, so they should show in the thumbnails.
All that could make it complicated I guess.
Thanks.

The background layer can not be moved. If the objects are anchored to the layer, when you move the layer the objects stay in the same location in the layer, but if the layer is moved the objects also move along with the layer. If the objects are anchored to a layer they cannot be moved off the layer.
If you need to be able to move the "background image" it will have to be added to a layer and resized to fit layer 0. Layer 0 or the background could be made transparent, so then you could move the background image.
With respect to the layer images and the thumbnail, it could get messy drawing all the layers as a thumbnail but it is possible.

| if I load an image and layer 0 is not locked, I can move the image around. I will have to look at my code as I know that I can move a bitmap on layer zero with the boxes staying at the same place independently of the image all in the same layer. I use the boxes to create a template to fit the loaded image. |

Thanks Bill. Let me look at the code and see if I can make it work with XE and 5.2.2
Appreciate the help really.

Thanks Bill. I can really only look at the code. Even modifying it to work under 5.2.2 and XE gives me errors.
Anyway, I may have found a way by looking at your code. It's still not 100 % working but it is getting there. Look below
procedure TMainform.Refreshlayerviewer;
var
i, idx: Integer;
begin
// ShowMessage('refresh layer viewer:');
LayerView.CenterSelected;
LayerView.Clear;
for i := 0 to ImageEnVect.LayersCount - 1 do
begin
ImageEnVectPreview.LayersClear;
ImageEnVectPreview.RemoveAllObjects;
ImageEnVectPreview.Assign(ImageEnVect.layers[i].Bitmap);
if i = ImageEnVect.LayersCurrent then
ImageEnVect.DrawObjectsToBitmap(ImageEnVectPreview.IEBitmap, True, True);
ImageEnVectPreview.Update;
ImageEnVectPreview.LayersMergeAll;
idx := LayerView.AppendImage;
LayerView.SetIEBitmap(idx, ImageEnVectPreview.IEBitmap);
if i = 0 then
LayerView.ImageTopText[0].Caption := 'Background'
else
LayerView.ImageTopText[i].Caption :=
string(ImageEnVect.layers[ImageEnVect.LayersCurrent].Name);
end;
LayerView.SelectedImage := ImageEnVect.LayersCurrent;
LayerView.Update;
end; |

| the only thing that prevents the code to work fully is that I need to detect if a layer has objects anchor to it and then only copy the objects from this layer and not all the objects. the drawobjectstobitmap copies every objects regardless on which layers they are anchored to. |

that is easy enough... just draw one object at a time for all objects in a layer:
procedure DrawOneObjectToBitmap(hobj: integer; target: TIEBitmap; Antialias: boolean = true; AdaptBitmapPixelFormat: boolean = true);
Something like this (Untested):
for i:= 0 to ImageEnVect1.LayerCount-1 do
begin
for j := ImageEnVect1.ObjectsCount - 1 downto 0 do
begin
ihobj := ImageEnVect1.GetObjFromIndex(j);
// if hobj is on current layer then copy the object
iobjLayer := ImageEnVect1.ObjLayer[ihobj];
if iobjLayer = i then
ImageEnVect1.DrawOneObjectToBitmap(ihobj, ImageEnMView1.IEBitmap, True);
end;
end;

Awesome. I was not aware of this command. There are so many I am sure I do not know.
Let me play to see if I do not anchor the object to the layer, where would the object show?
Not sure if I want it to show on layer zero I guess.
Best, |

If you do not anchor a object to a layer, objects are just painted over all layers... so no matter which layer is selected you can select any object...
