programatically testing if there was assigned an image to a TImage on a form

Question

There's a TImage component on a form in my program.

In some situation, the program must test:

If "there is an image assigned to the picture property of the TImage component" then .............

How can I do this?

Thanks in advance.

You don't say, but I'll assume you're talking about Delphi.

You can check whether there's a bitmap in the TImage control by testing:

if Image.Picture.Bitmap.Width > 0 then
  // do whatever
