示例1: DrawTextOnLayer

{
int LayerIndex = MainDataModule->ImageList1->Destination->Items[Index]->Layers->Count - 1;
if(LayerIndex >= 0) {
TLayer * Layer = MainDataModule->ImageList1->Destination->Items[Index]->Layers->Items[LayerIndex];
String SourceName = Layer->Name;
TSize Size;
TCustomBitmapItem * Item;
// Create a new source image if earlier its was not
if(!MainDataModule->ImageList1->BitmapItemByName(SourceName, Item, Size)) {
