◆ CalculateCache()

virtual bool iimg::CReflectedBitmapBase::CalculateCache ( const ChangeSet & changeSet )

protectedvirtual

Calculate cache.

It will be called, if cache was not valid and EnsureCacheValid() is called. Default implementation does nothing and is provided to ensure that base class for all derived classes implement this method.

Reimplemented from istd::TCachedUpdateManagerWrap< iimg::CGeneralBitmap >.

◆ ConvertFromQImage()

virtual bool iimg::CReflectedBitmapBase::ConvertFromQImage ( const QImage & image )

protectedpure virtual

◆ ConvertToQImage()

virtual bool iimg::CReflectedBitmapBase::ConvertToQImage ( QImage & result ) const

protectedpure virtual

◆ CopyImageFrom()

virtual bool iimg::CReflectedBitmapBase::CopyImageFrom ( const QImage & image )

virtual

Copies the image data from a QImage object.

Parameters

image QImage object.

Returns: true if it succeeds, false if it fails.

Implements iimg::IQImageProvider.

◆ GetQImage()

virtual const QImage & iimg::CReflectedBitmapBase::GetQImage ( ) const

virtual

Gets a QImage object.

Implements iimg::IQImageProvider.
