TIEDBMultiBitmap.ReleaseBitmap

Declaration

procedure ReleaseBitmap(idx: Integer; SaveChanges: Boolean);

Description

Releases the bitmap created with GetBitmap or GetTIEBitmap method.

If saveChanges then your modifications will be written to the database (TDataset.Edit/Post will be called).

Note: If Mode = dmRecordFrames, this method does NOT update the database. You will need to call UpdateDatabaseImage

Parameter	Description
idx	The image index to release
saveChanges	If true (default), changes to the bitmap will be written to the database

Example

// Prompt the user to apply effects to a database image
var
  bmp: TIEBitmap;
  proc: TImageEnProc;
  bChanged: Boolean;
begin
  if ImageEnMView1.SelectedImage < 0 then
    exit;

  bmp := fDBMBitmap.GetTIEBitmap( ImageEnMView1.SelectedImage );
  proc := TImageEnProc.CreateFromBitmap( bmp );
  proc.PreviewsParams := proc.PreviewsParams + [ prppDefaultLockPreview ];
  bChanged := proc.DoPreviews();
  fDBMBitmap.ReleaseBitmap( ImageEnMView1.SelectedImage, bChanged );
  FreeAndNil( proc );
end;
