Overview

Using CFBsBitmap in an own (non-UI) process

Description

CFbsBitmap gives KErrCouldNotConnect errors in, for example, an own server implementation.

Solution

CFbsBitmap requires connection to the font and bitmap server, which must be done manually in own processes, for example, server implementations.
One solution is to connect to RWsSession, which connects to the font and bitmap server. Usually server implementations do not and cannot use the UI directly, so RWsSession is not desired.
A connection to the font and bitmap server can be made with RFbsSession::Connect(), and when shutting down, a call to RFbsSession::Disconnect() should be made.
