Detailed Description

A CachedBitmap is created by the renderer in a format of its choosing.

CachedBitmaps are generally left alone by libcore, but the BitmapData API provides a way of manipulating bitmaps. For this reason an image() function is required, which must return a GnashImage for manipulation.

Constructor & Destructor Documentation

gnash::CachedBitmap::CachedBitmap ( ) [inline]

virtual gnash::CachedBitmap::~CachedBitmap ( ) [inline, virtual]

Member Function Documentation

virtual void gnash::CachedBitmap::dispose ( ) [pure virtual]

Free the memory associated with this CachedBitmap.

This allows ActionScript a little bit of control over memory.

Implemented in gnash::agg_bitmap_info.

virtual bool gnash::CachedBitmap::disposed ( ) const [pure virtual]

Whether the CachedBitmap has been disposed.

A disposed CachedBitmap has no data and should not be rendered.

Implemented in gnash::agg_bitmap_info.

virtual GnashImage& gnash::CachedBitmap::image ( ) [pure virtual]

Return a GnashImage for manipulation.

The changes to the data must be cached before the next rendering.

Implemented in gnash::agg_bitmap_info.
