Is it possible to rotate the metafile image without converting it to the bitmap?

Question

I need to rotate the TMetafile image, at least by 90 degrees step. It is easy to rotate it by drawing my metafile on a bitmap canvas and then rotating the bitmap, but I would prefer to keep it in vector image format. Is this possible at all? If yes, then how can I do that?

Answer 1

Create a second metafile. Use SetWorldTransform to create the rotation transform. Draw the first metafile onto the second and let the transform do the rest.
