Detailed Description

template<class Access, class Bitmap, Access *(Bitmap::*)() Acquire>
class vcl::ScopedBitmapAccess< Access, Bitmap, Acquire >

This template handles BitmapAccess the RAII way.

Please don't use directly, but through the ready-made typedefs ScopedReadAccess and ScopedWriteAccess in classes Bitmap and AlphaMask.

Use as follows: Bitmap aBitmap; Bitmap::ScopedReadAccess pReadAccess( aBitmap ); pReadAccess->SetPixel()...

Bitmap aBitmap2; BitmapScopedWriteAccess pWriteAccess( bCond ? aBitmap2.AcquireWriteAccess() : 0, aBitmap2 ); if ( pWriteAccess )...

Attention: \n for practical reasons, ScopedBitmapAccess stores a

reference to the provided bitmap, thus, make sure that the bitmap specified at construction time lives at least as long as the ScopedBitmapAccess.
