win32 display jpg file

[Ilariu Raducan]

Thank you all for your quick replays.

I check the last outline and I can share my findings with you

in document  OnOpenDocument add:
	im = Image.open(filename)
         self.dib = ImageWin.Dib(im.mode,im.size)
         self.dib.paste(im)
	#make in redraw
	#self.frame.InvalidateRect()
	#or
	#self.UpdateAllViews()
in View
     def OnDraw(self,dc):
         self.dib.expose(dc.GetHandleAttrib())

Regards,
Lale
