Hi all.
I have TImageEnDBView attached to database;
How can i post changes to database after some corrections
via ImageEnView.Proc.DoPreviews ...
But I will not do dataset.edit before ImageEnView.Proc.DoPreviews
and post after ...

Maybe there is some way to get some actual raw data from ImageEnView, without any information about file format, for saving to my blob field?

Hi

The usual way to do it would be:

// Color adjust...
procedure TMainForm.Button7Click(Sender: TObject);
begin     
  Table1.Edit;
  if ImageEnDBView1.Proc.DoPreviews(ppeColorAdjust) then
    Table1.Post
  else
    Table1.Cancel;
end;


But if you do not want to wrap in an Edit/Post then either:
- Manually save the new bitmap (ImageEnDBView1.IEBitmap)
- Review the particular changes made using ImageEnDBView1.Proc.IPDialogParams:
