constructor Create; override;
__fastcall virtual TMetafile();
Instantiates a metafile object.
Call Create to instantiate a metafile at runtime.
To create a metafile image from scratch, draw the image in a metafile canvas. When the metafile canvas is destroyed, it transfers the image into the metafile object provided to the metafile canvas constructor. After the image is drawn on the canvas and the canvas is destroyed, the image is 'playable' in the metafile object.
