delphi - How to put an image in the Activex Control Button -

i not sure how going make procedure put image in button, seems no tbitbtn or tspeedbutton in activex control wizard, when button stretch image stretched.

the project .dpr

library buttonxcontrol1;  uses   comserv,   buttonxcontrol1_tlb in 'buttonxcontrol1_tlb.pas',   buttonimpl1 in 'buttonimpl1.pas' {buttonx: coclass},   about1 in 'about1.pas' {buttonxabout};  {$e ocx}  exports   dllgetclassobject,   dllcanunloadnow,   dllregisterserver,   dllunregisterserver;  {$r *.tlb}  {$r *.res}  begin end.
