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.

Member Function Documentation
§ dispose()
|
pure virtual |
Free the memory associated with this CachedBitmap.
This allows ActionScript a little bit of control over memory.
Implemented in gnash::renderer::openvg::OpenVGBitmap, and gnash::agg_bitmap_info.
§ disposed()
|
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, and gnash::renderer::openvg::OpenVGBitmap.
Referenced by gnash::renderer::openvg::StyleHandler::operator()().
§ image()
|
pure virtual |
Return a GnashImage for manipulation.
The changes to the data must be cached before the next rendering.
Implemented in gnash::renderer::openvg::OpenVGBitmap, and gnash::agg_bitmap_info.
Referenced by gnash::renderer::openvg::OpenVGBitmap::applyPatternBitmap(), gnash::renderer::openvg::OpenVGBitmap::OpenVGBitmap(), gnash::registerBitmapDataNative(), and test_renderer().
