Need some help working with JPEGs...

[CoffeeAddict19]

Basically what I'm trying to do is add the functionality to let the user select a JPEG background image for my game, as eye candy. MFC has functions for handling bitmaps but nothing for JPEGs or other image formats. I'd like to load a JPEG and convert it to a bitmap so that I can blit it as necessary. What is the best way to do this? I'd rather do it without tacking on a huge library to my program, if possible.

Look at the GDI+ library. If you are aiming only at Windows XP, it ships with the DLL.

If you use GDI+ it's pretty simple...

// Assuming GDI+ is initialized...

Gdiplus::Bitmap SrcBitmap(L"C:\\Images\\MyJPEG.jpg", FALSE);
HBITMAP hBitmap;
SrcBitmap.GetHBITMAP(Gdiplus::Color(0xFF,0xFF,0xFF), &hBitmap);
