JPEG compressing without DLLs

Question

I want to convert raw RGB image data (I could add BMP header if necessary) to JPEG on Windows. Is it possible to do so without DLLs? I tried statically compiling IJG jpeglib, but I have VC++ 9, and it only works for VC++ 10

Use GDI+ to save the image to a file. For example, see http://msdn.microsoft.com/en-us/library/ms535407(VS.85).aspx for how to save to a file. Specify the JPEG encoder. To load the image into the Image class, you can use the Bitmap class (inherits from Image). Several methods are available: http://msdn.microsoft.com/en-us/library/ms536286(VS.85).aspx.

GDI+ comes with Windows XP and newer and can be redistributed for older Windows versions. So you probably won't need to bundle anything newer.
