| Yes, you can. It will use TBitmap to store the image loaded with LoadFromFile. |

Yes, I received it.
The problem is that the image is too big and it cannot be converted to TBitmap (and RGB). |

| Is there solution to combine annotations with background for this image? |

A TCanvas object (required by drawing primitives) is necessary, and unfortunately this is available only in TBitmap, that is not available for a RGB 18724x13244 image.
Anyway next minor release will allow drawing into BW images, without RGB conversion, as experimental feature. |

| TBitmap is still necessary (due the TCanvas), so legacy bitmap cannot be maintained. Anyway pixel format is maintained to Black/White allowing to process big bitmaps. |

No, it is done automatically. For example, you will be able to do:
imageenvect1.LegacyBitmap:=false;
imageenvect1.IO.LoadFromFile('652-100-000.TIF');
imageenvect1.AddNewObject(iekline, rect(10,10,100,100), clBlack); // just an example
imageenvect1.CopyObjectsToBack(true, true, false); // last parameter avoid to change from BW to RGB
imageenvect1.RemoveAllObjects();
Note last parameter of CopyObjectsToBack (available from next release) avoid CopyObjectsToBack to convert from BW to RGB.
Note also that you will be able to use only colors like clBlack or clWhite for objects, of course. |

New bug with
ImageEnView1->CopyObjectsToBack(true, true, false)
after this command all image object are stretched
With
ImageEnView1->CopyObjectsToBack(true, true, true) - all is OK |

Sorry, I cannot replicate. Tried:
ImageEnVect1.AddNewObject(iekBox, Rect(10, 10, 100, 100), clRed);
ImageEnVect1.CopyObjectsToBack(true, true, false);
ImageEnVect1.RemoveAllObjects();
Of course it assumes you have an RGB (24 bit) bitmap, otherwise it is no-sense to set last parameter to False.

No. Background is black-and-white
Reason to use
CopyObjectsToBack(true, true, FALSE);
is to prevent image converting to 24 bit at combining |

my test
=======
file.tif is there
www.graphicregion.com/file.tif
//---------------------------------------------------------------------------
void __fastcall TForm1::ButtonOpenFileClick(TObject *Sender)
{
ImageEnVect1->IO->LoadFromFile("file.tif");
ImageEnVect1->IO->Params->ImagingAnnot->CopyToTImageEnVect(ImageEnVect1);
}
//---------------------------------------------------------------------------
void __fastcall TForm1::ButtonCopyToBackClick(TObject *Sender)
{
ImageEnVect1->CopyObjectsToBack(true, true, false);
ImageEnVect1->RemoveAllObjects();
}
//--------------------------------------------------------------------------- |
