The following C++ code places an enhanced metafile onto the clipboard, which can then be pasted into powerpoint, wordpad, paint, LO impress, etc. The LO internal drawing functions seem to skip some of the metafile records or misinterpret them resulting in image corruption, the other aforementioned applications handle it correctly.
