Graphics.FillRectangle vs Graphics.FillPath speed

[Mark Ingram]

Hi, I would like to know which is the faster method to call,
FillRectangle or FillPath.

I have a path which is essentially a square, except for rounded corners,
so I can end up with 2 almost identical lines of code for the fill, but
want to know which is "more correct".

LinearGradientBrush backColorBrush = new
LinearGradientBrush(this.ClientRectangle, backColor, backColor2,
linearGradientMode);
e.Graphics.FillPath(backColorBrush, path);
-or-
e.Graphics.FillRectangle(backColorBrush, this.ClientRectangle);

Any help or opinion greatly received,

Thanks

Mark,

They both produce the same effect, it's just that calling FillPath will
require more work on your part (since you have to construct the path).

I wouldn't be surprized if FillRectangle called FillPath (at the windows
API layer, not the .NET API layer), doing exactly what you would be doing by
creating the path.

I don't think that any one is "more correct", it's just a matter of how
much extra work you want to do for the same result.

Hope this helps.

Thanks for the quick reply, the amount of effort required in each is the
same, I have access to both the client rectangle and the graphics path.
Will probably stick with FillPath then.

Thanks,
