How to use method L_FreeBitmap

Hello,

Lets say I need to get the Width of a specific bitmap within a bitmap list.
I use my own method GetWidthFromBitmap for this .
In this method I get a specific bitmap into MyBitmap (of type BITMAPHANDLE) by the method L_GetBitmapListItem.
My question - do I need to call at the end of my method (GetWidthFromBitmap):
L_FreeBitmapMyBitmap);
?

Here is my method:

function TNewImagingManipulator.GetWidthFromBitmap(): Integer;
var
MyBitmap: BITMAPHANDLE;
ImagesListHandle: HBITMAPLIST;
begin
L_GetBitmapListItem(ImagesListHandle, 0, @MyBitmap, sizeof(BITMAPHANDLE));

Result := MyBitmap.Width;

L_FreeBitmap(@MyBitmap);
end;


Plesae explain.

Thanks a lot in advance.

I have to mention that
ImagesListHandle: HBITMAPLIST;
is a parameter for the method, meaning I dont want to free ImagesListHandle.

By freeing Bitmaphandle, you are already freeing the bitmap in the Bitmaplisthandle as well.
You must not call L_FreeBitmap for the list item you retrieved using L_GetBitmapListItem.
You only need to free the entire list after you're done with it.
