Changes a Windows device independent bitmap (DIB) to a LEAD bitmap. The new LEAD bitmap is stored in the specified LBitmapBase object's internal LEAD bitmap handle. This function results in only one copy of the bitmap, and it invalidates the DIB handle.

static L_INT LChange::ChangeFromDIB(pLBitmap, uStructSize, hDIB)

Parameters

LBitmapBase * pLBitmap
