Introduction

This sample is an MFC application using the document/view architecture that can load, display and print graphics files such as GIF, JPEG, BMP (bitmap), ICO (icon), WMF (metafile) and EMF (Win32-enhanced metafile). It shows

• how to use the OleLoadPicturePath() function and the IPicture interface to load and display those graphics files.

(Look into the ImgViewerDoc.cpp, ImgViewerView.cpp and MainFrm.cpp files.)
• how to support more than one file extension per MFC document type.

(Look into the MulExtDocTmp.cpp, MulExtDocTmp.h and ImgViewer.cpp files.)

(Note that LOADPIC.EXE does not handle palettes. As a result, it won't display a 256-color image correctly in 256-color mode. Also, it uses the OleLoadPicture() function instead of the OleLoadPicturePath() function.)
