If a suitable importer is not found the ComponentInstance // is set to NULL. err = GetGraphicsImporterForFile( &theFSSpec, // specifies the file to be drawn &importer ); // pointer to the returned GraphicsImporterComponent // get the native size of the image associated with the importer err = GraphicsImportGetNaturalBounds( importer, // importer instance &bounds ); // returned bounds OffsetRect( &bounds, 10, 45 ); window = NewCWindow( NULL, &bounds, "/pDraw Image", true, documentProc, (WindowPtr)-1, true, 0); // set the graphics port for drawing err = GraphicsImportSetGWorld( importer, // importer instance GetWindowPort( window ), // destination graphics port or GWorld NULL ); // destination GDevice, set to NULL uses GWorlds device // draw the image err = GraphicsImportDraw( importer ); // close the importer instance CloseComponent( importer );}
