Detailed Description

The DynamicShape class represents a mutable shape.

It is provides mutating functions for the SWF::ShapeRecord class that are used in the Flash drawing API. DynamicShape objects are not refcounted, so must be stack-allocated or wrapped in smart pointers.

Member Function Documentation

size_t gnash::DynamicShape::add_line_style ( const LineStyle & stl )

Add a line style, possibly reusing an existing one if existent.

Returns:: the 1-based offset of the line style, either added or found. This offset is the one required to properly reference it in gnash::path instances.

References gnash::SWF::ShapeRecord::addLineStyle(), and gnash::SWF::ShapeRecord::lineStyles().

Referenced by lineStyle().

void gnash::DynamicShape::add_path ( const Path & pth )

Add a path, updating _currpath and recomputing bounds.

TODO: make private? Only current user is BitmapMovieDefinition. It needs this function unless we provide a mean to add a Bitmap-Filled path

size_t gnash::DynamicShape::addFillStyle ( const FillStyle & stl )
