CIJLBitmap
v1.22 An MFC class to support loading DIB's and
Jpegs (Obsolete)
Welcome to CIJLBitmap, An
MFC class based in part on CBitmap and CPalette which provides support for loading Device
Independent Bitmaps (DIBS) and jpegs from disk. Support
is provided for Loading BMP's from file and resource, loading Jpeg files
and saving to BMP's on file.
Features
- Code is UNICODE enabled and
build configurations are provided.
- All code compiles cleanly at
level 4.
- Small footprint, total size
amounts to just c. 300 lines of code.
The enclosed zip file contains the
CIJLBitmap source code and a simple SDI MFC app which implements a simple DIB /
Jpeg viewer. For further details on how to use the
class have a look at the doc and view cpp files and the included
documentation.

Updates
V1.0 (3 April 2000)
V1.1 (10 April 2000)
- Now includes full support for palettes.
V1.2 (30 July 2000)
- Now supports loading of .gif and .ico. This is accomplished via the IPicture COM interface. Please note that to release code which uses the GIF format, you will need to obtain a license from Unisys.
- I have also removed the dependence on the Intel Jpeg Library as the IPicture interface supports loading Jpegs.
This means that the sample app is now just 23 K in size and only depends on
the normal Win32 DLLs (including OLE) as well as the MFC runtimes.
V1.21 (31 July 2000)
- Class is now derived from
CBitmap as before, Dropped support for ICO format as it was producing a
separate code path.
V1.22 (1 August 2001)
- Now includes support for saving back to a bmp file.
23 December 2005
- Please note that this code is now obsolete because ATL / MFC as of Visual
Studio .NET 2002 provides a "CImage" class which implements a superset of
the functionality of CIJLBitmap. You should update your code to use this
standard class instead of my CIJLBitmap class.
