Member Function Documentation

Palette const * LV::Morph::get_palette ( )

Returns the colour palette used.

Note: Only 8-bit morphs will have colour palettes.

Returns: Colour palette, or nullptr if there is none

Definition at line 140 of file lv_morph.cpp.

Referenced by run().

VisPluginData * LV::Morph::get_plugin ( )

Returns the plugin object.

Returns: Plugin object

Definition at line 72 of file lv_morph.cpp.

VisVideoDepth LV::Morph::get_supported_depths ( )

Returns the set of colour depths natively supported.

Returns: Set of supported depths

Definition at line 115 of file lv_morph.cpp.

bool LV::Morph::is_done ( )

Determines if morph has completed.

Returns: true if completed, false otherwise

Definition at line 146 of file lv_morph.cpp.

MorphPtr LV::Morph::load ( std::string const & name )

static

Creates a new Morph wit a plugin of a given name.

See Also: realize()

Parameters

name	Name of plugin to load

Returns: New morph, or nullptr if plugin failed to load

Definition at line 77 of file lv_morph.cpp.

bool LV::Morph::realize ( )

Realizes a morph.

This also calls the plugin init() method.

Returns: true on success, false otherwise

Definition at line 110 of file lv_morph.cpp.

bool LV::Morph::run	(	Audio const &	audio,
		VideoPtr const &	src1,
		VideoPtr const &	src2
	)

Runs the morph.

Note: The rendering will be performed on the Video set with set_video().

Parameters

audio	Audio data
src1	First source Video
src2	Second source Video

Returns: true on success, false otherwise

Definition at line 156 of file lv_morph.cpp.

void LV::Morph::set_progress ( float progress )

Sets the progress of a morph.

Parameters

progress Progress of morph (must be in [0.0, 1.0])

Definition at line 135 of file lv_morph.cpp.

void LV::Morph::set_time ( Time const & time )

Sets the morph duration.

Parameters

time Duration

Definition at line 130 of file lv_morph.cpp.

void LV::Morph::set_video ( VideoPtr const & video )

Sets the video target for rendering.

Parameters

video Video target
