well i am trying the easiest way :-)
I have defined a document type and in the constructor i specify two layer
StaticSchemeDocument::StaticSchemeDocument(void):
a2dCanvasDocument()
{
m_documentTypeName = _T("StaticSchemeDocument");
//create two layers one for the background image
// Clone the current layer setup
a2dLayers* docLayers = doc->GetLayerSetup()->Clone( bool deep = true );
// Create a new layer with an index above the predefined layers
a2dLayerInfo* layer = new a2dLayerInfo(wxLAYER_USER_FIRST,
wxT("BackgroundLayer"));
// Set layer available
layer->Set_Available(true);
//Set layer unselectable
layer->Set_Selectable (false);
// Add layer to to the a2dLayers
docLayers->Append(layer);
doc->SetLayerSetup(docLayers);
}
But know I am wondering how to choose in which layer i add object when i
make a Appen(cavnasObject) ?
When i was speaking about zoom, i meant that I wanted my background image
behave live canvas object when i zoom (scaling on the screen according to
zoom value)
