Canvas is TImage. No any loop. Thanks. RSK. If no loop, then I assume you see flicker when you resize the window. I understand that Delphi 7 has a flicker problem with TImage but I do not know the solution as I still use Delphi 5. You can try to set doublebuffered := true to the parent control of the TImage. best regards Back to top Ma Xiaoguang Guest Posted: Mon Aug 02, 2004 1:05 am    Post subject: Re: FillRect Hi, I have the same problem with Delphi 6. A friend which was in this forum has told me a method to handle the problem -- just to set the Stretch property of the TImage to True! Does it work with Delphi 7? I don't know, because I don't have it. Try the method. Good luck. Best regards. Xiaoguang "RSK" <Tecdiscuss (AT) Yahoo (DOT) com> wrote Quote: Hi, It's small (50*50 px). Canvas is TImage.
