I have a custom panel that draws lines and rectangles on its canvas. How can I draw the same things on the canvas of a Windows Metafile canvas so I can save the panel display as a wmf file? Thanks a lot.

If you are on Windows fpvectorial seems to be able to write wmf:

FpVectprial is included with Lazarus. See there for a start:

For other OS you would need to do wmf writing code yourself, iirc it is a rather simple format having drawing items (e.g. Line) and coordinates for doing so.

Things get a bit more complicated for EMF or EMF+:
