Loading 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. This topic provides an example of loading a multi-bitmap file.

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:\\resource\\apps\\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();
