How to load a bitmap from a file

Bitmaps can be stored in multi-bitmap (.mbm) files, which can be built from .bmp files as part of the abld process. Loading them has four stages:

1. Put the name of the bitmap file into a buffer.

2. Create a bitmap (CFbsBitmap).

3. Load the bitmap using CFbsBitmap::Load().

4. If an error is returned, leave and ensure the bitmap is cleaned up

// set the name of the multi-bitmap file containing the bitmaps
_LIT(KMBMFileName,"z:\\system\\apps\\GraphicsShell\\grbmap2.mbm");

// load the bitmap from an .mbm file
CFbsBitmap* bitmap = new (ELeave) CFbsBitmap();
CleanupStack::PushL(bitmap);
User::LeaveIfError(bitmap->Load(KMBMFileName,
  EMbmGrbmap2Smiley));
// EMbmGrbmap2Smiley is the ID of a bitmap in the .mbm file

...
// clean up
CleanupStack::PopAndDestroy();
