I save a file with:

ThisImageFile := MyPath + 'MyImage.png';
ImageEnView1.IO.SaveToFile(ThisImageFile);
CopyFile(ThisImageFile, TargetFile);


As you can see from this code, CopyFile needs the source file to exist.

So how can I ensure that right after "ImageEnView1.IO.SaveToFile" the file already exists?

Does "ImageEnView1.IO.SaveToFile" return only after the file already exists?

Or is there a mechanism to wait after "ImageEnView1.IO.SaveToFile" until the file exists?

Hi Peter

Please see:

https://www.imageen.com/help/TImageEnIO.SaveToFile.html

By default, SaveToFile is blocking. Also, in case of save error an exception is raised. So in your code above, "ThisImageFile" should always exist.

e.g.

ThisImageFile := MyPath + 'MyImage.png';
try
  ImageEnView1.IO.SaveToFile(ThisImageFile);
  CopyFile(ThisImageFile, TargetFile);
except
  ShowMessage('Could not save ' + ThisImageFile );
end;
