class PASCALIMPLEMENTATION TMetafileCanvas : public TCanvas
TMetafileCanvas allows applications to create metafile images from scratch.
Use TMetafileCanvas as a surface on which to draw a metafile image. When the canvas is destroyed, it transfers the image into the metafile object provided to the canvas constructor. After the image is drawn on the canvas and the canvas is destroyed, the image is 'playable' in the metafile object.
