You'll have to be a bit more specific, what doesn't work? Can you give us a bit more code? It all depends of the context, the prototype in itself is not wrong but if the ancestor has a Resize property you might need to overload this one to as the GrayScale procedure.<br />
<br />
Do you have an compiler error? Do you have a run-time error? Is it just the procedure that does do what it is suppose to do?

<div class="content wysiwyg-content">
This line works:<br />
Procedure GrayScale(Value: TImage); overload;<br />
<br />
Can anyone tell me why this don't work?<br />
Procedure Resize(Value: TImage; Width: Integer; Height: Integer);<br />
<br />
Are there missing something?<br />
<br />
&quot;It is for a component&quot;
